Abstract
The environmental crises defining the Anthropocene demand ubiquitous mitigation efforts, met with collective support. Yet, disengagement and disbelief surrounding planetary health threats are pervasive, especially in the USA. This scepticism may be influenced by inadequate education addressing the scope and urgency of the planetary health crisis. We analysed current K-12 science standards related to planetary health throughout the USA, assessing their quality and potential predictors of variation. While planetary health education varies widely across the USA with respect to the presence and depth of terms, most science standards neglected to convey these concepts with a sense of urgency. Furthermore, state/territory dominant political party and primary gross domestic product (GDP) contributor were each predictive of the quality of planetary health education. We propose that a nation-wide science standard could fully address the urgency of the planetary health crisis and prevent political bias from influencing the breadth and depth of concepts covered.

Racial misconceptions of the theory of evolution predict opposition to the theory and science in general among a sample of Zimbabwean university students. Heliyon 2023; 9:e16783. [PMID: 37313158 PMCID: PMC10258415 DOI: 10.1016/j.heliyon.2023.e16783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 05/18/2023] [Accepted: 05/26/2023] [Indexed: 06/15/2023] Open
Abstract
The theory of evolution has often been misconceived and often associated with racist undertones and insinuations towards Black Africans, who are assumed to be less evolved and thus closer to "apes" genetically than other, presumably more advanced racial groups. In this research was thus tested the hypothesis that misconceptions surrounding Charles Darwin's Theory of Evolution, particularly racial ones, would predict a lack of acceptance of the theory in particular, and the entirety of the science enterprise in general among a sample of Black Zimbabweans. We also tested the impact of spirituality on both acceptance of evolution and science. The hypotheses received support from the findings and they are discussed in line with pedagogy surrounding evolution and science. The findings of the most central importance were that racial misconceptions, general misconceptions and spirituality predicted both acceptance of evolution and science. In turn, the effects of all these exogenous variables on acceptance of science were mediated by lack of acceptance of evolution.

Abstract
UNLABELLED Climate change science is complex and perceived to be controversial in nature by some stakeholders. Yet from the perspective of educators and policy makers, climate change science is an important topic to be taught in secondary science education. The presence of controversy can influence teachers' instructional decisions and cause confusion about the science of climate change. This study examines the complex nature between science teacher beliefs and the impact on their instructional practices of climate change-centered curriculum. Findings from the study suggest teachers have strong beliefs about the causes and implications of climate change. However, due to the controversial nature of the topic, the current US political climate, and fear of resistance from stakeholders, teachers did not espouse these beliefs within their instruction of the curriculum and instead remained "neutral" when teaching about climate change.

Abstract
Background Even though evolution is the overarching principle that connects all areas of biology, a significant proportion of pre-service teachers do not intend to teach evolution, minimize the teaching of evolution, or teach alternative ideas in biology classes. To prevent adverse teaching practices and promote effective pre-service teacher education, we aimed to identify and analyze variables that foster or hinder their behavioral intentions to teach evolution. Method We adopted a behavioral psychology research perspective and developed a research model based on the theory of planned behavior to examine behavioral intentions for teaching evolution in biology classrooms. We extended the model with additional variables that have been delineated by teacher education research as essential determinants for the behavioral intention to teach evolution. We proposed several hypotheses suggesting that the attitude toward teaching evolution, subjective norms, perceived behavioral control, personal religious faith, perceived usefulness, and knowledge about evolution determine a person’s behavioral intention. We conducted a quantitative cross-sectional study in teacher education to test the hypotheses and surveyed N = 339 pre-service biology teachers using an online questionnaire. We analyzed the data using a two-stage structural equation model. Results We were able to confirm all proposed hypotheses. The most important results revealed that pre-service teachers’ knowledge about and perceived usefulness of evolution are only moderately pronounced. Moreover, the subjective norm is a predictor not only of behavioral intention but also of the attitude toward teaching evolution. The variable of perceived behavior control partly moderates the relationship between knowledge about evolution and behavioral intention. Additionally, perceived usefulness is an important and marginally stronger predictor of a person’s attitude than personal religious faith. Conclusion The extended model of the theory of planned behavior has highlighted the need for educational programs to increase knowledge about and the perceived usefulness of evolution even stronger. The findings delineated the effects of essential determinants on behavioral intentions and provided information about the necessary levers of teacher education.

Abstract
Background Although progress has been made in evolution education, many educators face significant barriers in their efforts to teach evolution specifically, and science in general. The purpose of this study was to identify faculty-perceived barriers to teaching evolution, specifically in religiously affiliated institutions or institutions with a highly religious student body, as well as resources faculty feel would help promote discourse around faith, evolution and science. To do this, we held a workshop with teams consisting of a science professor, a theologian and a pastor (of the predominant on-campus faith tradition) from 17 different institutions of higher education with highly religious student bodies for the purpose of helping them to create a curriculum to address perceived conflicts between science and faith. During the workshop, participants created posters identifying barriers they face and resources they perceive as helpful. These posters were analyzed for prevalent themes and framed within an ecological model of behavior. Results These teams identified prevalent barriers at each level of the ecological model. Intrapersonal factors included a fear of rocking the boat and a fear of student conflict. Interpersonal factors included perceived student lack of knowledge, student ideology, and student apathy. Institutional factors included work politics, a lack of relevant discourse surrounding the conflict, and mixed messaging to students. Community factors included social norms associated with various student demographics. And public policy factors included local and state government attempts to limit the teaching of evolution. Additionally, participants identified resources that they felt would facilitate overcoming conflict including colleagues as change agents, various assets, and tools to negate conflict. Conclusions We determined that many of the concerns are addressable, and many resources are attainable. We urge the community to work toward these solutions. Additionally, we compare our findings to what the literature has shown and discuss the implications of faculty perceptions as compared to the published literature.

Abstract
OBJECTIVE To assess the potential for a new channel for effective vaccine health communication in the United States: the nation's health education teachers. METHODS Content analysis of current curricular standards governing health education in the fifty states and the District of Columbia, and a 2019 nationally representative survey of middle and high school health education teachers in the United States. RESULTS Only 12 states require any discussion of vaccines or immunization, and none provide detailed guidance to teachers on critical knowledge that might help young adults make wise immunization decisions. Only 42% of teachers discuss benefits of vaccination and immunization in their classes. In contrast to the teaching of evolution and climate change, only a small minority (2.4%) are classified as vaccine skeptics. CONCLUSIONS Public school health education classes are an under-utilized health communication channel with the unrealized potential to convey medically accurate information to millions of young Americans. Low levels of vaccine skepticism among teachers suggest that this channel can be effectively utilized to improve vaccination uptake and thereby improve collective health outcomes.

Abstract
Anthropogenic climate change threatens the structure and function of ecosystems throughout the globe, but many people are still skeptical of its existence. Traditional "knowledge deficit model" thinking has suggested that providing the public with more facts about climate change will assuage skepticism. However, presenting evidence contrary to prior beliefs can have the opposite effect and result in a strengthening of previously held beliefs, a phenomenon known as biased assimilation or a backfire effect. Given this, strategies for effectively communicating about socioscientific issues that are politically controversial need to be thoroughly investigated. We randomly assigned 184 undergraduates from an environmental science class to one of three experimental conditions in which we exposed them to short videos that employed different messaging strategies: (a) an engaging science lecture, (b) consensus messaging, and (c) elite cues. We measured changes in student perceptions of climate change across five constructs (content knowledge, acceptance of scientific consensus, perceived risk, support for action, and climate identity) before and after viewing videos. Consensus messaging outperformed the other two conditions in increasing student acceptance of the scientific consensus, perceived risk of climate change, and climate identity, suggesting this may be an effective strategy for communicating the gravity of anthropogenic climate change. Elite cues outperformed the engaging science lecture condition in increasing student support for action on climate, with politically conservative students driving this relationship, suggesting that the messenger is more important than the message if changing opinions about the necessity of action on climate change is the desired outcome. Relative to the other conditions, the engaging science lecture did not support change in students' perceptions on climate, but appealing to student respect for authority produced positive results. Notably, we observed no decline in students' acceptance of climate science, indicating that none of the conditions induced a backfire effect.

Are scientists biased against Christians? Exploring real and perceived bias against Christians in academic biology. PLoS One 2020; 15:e0226826.

Abstract
Christians are one of the most underrepresented groups in science, and one potential explanation is that scientists have a bias against Christian students, which could discourage and actively prevent Christian students from becoming scientists. Although there is a general perception in society that there is bias against Christians in science, we do not know whether science students, who frequently interact with scientists, perceive this bias. Further, no researchers have attempted to experimentally document the existence of bias against Christians in science. To address these gaps in the literature, we designed three studies. In the first study, we found that college science students report a perceived bias against Christians in science and that evangelical Christians perceive greater bias than Catholic and non-Christian students. Then in two studies, biology professors evaluated Ph.D. program applicants and we examined whether the professors rated a student less favorably when the student revealed a Christian religious identity. We found no statistically significant differences in how biology professors rated a student who was President of the Christian Association compared to a student who was President of the Atheist Association or a student who was President of the Activities Association. However, in Study 3, biology professors did rate a Christian student who went on a mission trip with Campus Crusade for Christ as less hireable, less competent, and less likeable than a student who did not reveal a Christian identity. Taken together, these studies indicate that perceived bias against Christians in science may contribute to underrepresentation of Christians but actual bias against Christians in science may be restricted to a specific type of Christianity that scientists call fundamentalist and/or evangelical.

Abstract
Evolution is both a fact and a theory. Evolution is widely observable in laboratory and natural populations as they change over time. The fact that we need annual flu vaccines is one example of observable evolution. At the same time, evolutionary theory explains more than observations, as the succession on the fossil record. Hence, evolution is also the scientific theory that embodies biology, including all organisms and their characteristics. In this paper, we emphasize why evolution is the most important theory in biology. Evolution explains every biological detail, similar to how history explains many aspects of a current political situation. Only evolution explains the patterns observed in the fossil record. Examples include the succession in the fossil record; we cannot find the easily fossilized mammals before 300 million years ago; after the extinction of the dinosaurs, the fossil record indicates that mammals and birds radiated throughout the planet. Additionally, the fact that we are able to construct fairly consistent phylogenetic trees using distinct genetic markers in the genome is only explained by evolutionary theory. Finally, we show that the processes that drive evolution, both on short and long time scales, are observable facts.

Scientific aptitude better explains poor responses to teaching of evolution than psychological conflicts. Nat Ecol Evol 2018; 2:388-394.

Abstract
It is considered a myth that non-acceptance of scientific consensus on emotive topics is owing to difficulties processing scientific information and is, instead, owing to belief-associated psychological conflicts, the strongest non-acceptors being highly educated. It has been unclear whether these results from adults explain variation in response to school-level teaching. We studied a cohort of UK secondary school students (aged 14-16) and assessed their acceptance and understanding of evolution. In addition, to address their aptitude for science we assessed their understanding of genetics and their teacher-derived assessment of science aptitude. As both models predict, students with low initial evolution acceptance scores showed lower increases in the understanding of evolution. Contrary to conventional wisdom, this effect is better explained by lack of aptitude: before teaching, students with low acceptance had lower understanding of both evolution and of genetics; the low-acceptance students sat disproportionately in the foundation (rather than higher) science classes; low-acceptance students showed lower increments in the understanding of genetics; and student gain in the understanding of evolution correlated positively with gain in the understanding of genetics. We find no evidence either for a role for psychological conflict in determining response to teaching or that strong rejectors are more commonly of a higher ability. From qualitative data we hypothesize that religious students can avoid psychological conflict by adopting a compatibilist attitude. We conclude that there are students recalcitrant to the teaching of science (as currently taught) and that these students are more likely to not accept the scientific consensus. Optimizing methods to teach recalcitrant students is an important avenue for research.

Abstract
Charles Darwin is largely unknown and poorly understood as a historical figure. Similarly the fundamental principles of evolution are often misstated, misunderstood, or entirely rejected by large numbers of Americans. Simply trying to communicate more facts about Darwin, or facts supporting the principles of evaluation, is inadequate; neither students nor members of the public will care or retain the information. On the contrary, building facts into a one-on-one conversational narrative creates a memorable opportunity to learn. Here we create a digital media, self-guided question and answer 'synthetic interview' with Charles Darwin. Questions are derived from a survey of nearly 1,000 people. Answers spoken by an actor portraying Darwin are derived from Darwin's own writings. Questions on modern topics are answered by scientists, theologians, and lawyers. First produced as a museum exhibit and then later reproduced as an app (iOS/Android), the Darwin Synthetic Interview has been evaluated with more than 3,000 surveyed users, of which 69% indicated that they learned and more than 75% would recommend the experience. Students who interacted with the synthetic interview in a classroom setting found answers were unexpected and clarifying. Using a format of personal narrative, the Darwin Synthetic Interview creates a new way to engage students and the public in a process of self-directed discovery of a topic that is often considered difficult to teach.

Abstract
Students' religious beliefs and religious cultures have been shown to be the main factors predicting whether they will accept evolution, yet college biology instructors teaching evolution at public institutions often have religious beliefs and cultures that are different from their religious students. This difference in religious beliefs and cultures may be a barrier to effective evolution education. To explore when evolution instructors have similar religious cultures and beliefs as their students, we interviewed 32 evolution instructors at Christian universities nationwide about their practices and experiences teaching evolution. Christian university instructors emphasized teaching for acceptance of evolution while holding an inclusive teaching philosophy that they perceived led to a safe environment for students. Additionally, almost all instructors reported using practices that have been shown to increase student acceptance of evolution and reduce student conflict between evolution and religion. Further, we found that these instructors perceived that their own religious backgrounds have guided their decisions to teach evolution to their students in a culturally competent way. We discuss how these data, combined with past research literature on public college instructors, indicate that cultural competence could be a useful new framework for promoting effective evolution education in higher education institutions.

Abstract
What is the best way to teach evolution? As microevolution may be configured as a branch of genetics, it being a short conceptual leap from understanding the concepts of mutation and alleles (i.e., genetics) to allele frequency change (i.e., evolution), we hypothesised that learning genetics prior to evolution might improve student understanding of evolution. In the UK, genetics and evolution are typically taught to 14- to 16-y-old secondary school students as separate topics with few links, in no particular order and sometimes with a large time span between. Here, then, we report the results of a large trial into teaching order of evolution and genetics. We modified extant questionnaires to ascertain students’ understanding of evolution and genetics along with acceptance of evolution. Students were assessed prior to teaching, immediately post teaching and again after several months. Teachers were not instructed what to teach, just to teach in a given order. Regardless of order, teaching increased understanding and acceptance, with robust signs of longer-term retention. Importantly, teaching genetics before teaching evolution has a significant (p < 0.001) impact on improving evolution understanding by 7% in questionnaire scores beyond the increase seen for those taught in the inverse order. For lower ability students, an improvement in evolution understanding was seen only if genetics was taught first. Teaching genetics first additionally had positive effects on genetics understanding, by increasing knowledge. These results suggest a simple, minimally disruptive, zero-cost intervention to improve evolution understanding: teach genetics first. This same alteration does not, however, result in a significantly increased acceptance of evolution, which reflects a weak correlation between knowledge and acceptance of evolution. Qualitative focus group data highlights the role of authority figures in determination of acceptance. What is the best way to teach evolution? We hypothesised that if students know the fundamental concepts of genetics, then this might help them understand evolution better. To evaluate this, we performed a large trial in which pupils in United Kingdom secondary schools were either taught genetics and then evolution or evolution and then genetics. We found that the students being taught genetics first had a 5%–10% improvement in their understanding of evolution, above that shown in the group taught evolution first. The change was seen in both higher- and foundation-ability classes. Indeed, in the foundation classes the genetics-first approach was the only approach that enabled an increase in evolution understanding. Teaching genetics first comes at no cost to genetics understanding (and may even improve it). However, the genetics-first approach was no different from the evolution-first approach in helping the acceptance of evolution. Qualitative follow-up studies indicated a major role for authority figures in determining acceptance, potentially explaining the weak correlation between understanding and acceptance. These results suggest a simple, minimally disruptive, zero-cost intervention to improve evolution understanding: teach genetics first.

Abstract
Incomprehension and denial of the theory of evolution among high school students has been observed to also occur when teachers are not equipped to deliver a compelling case also for human evolution based on fossil evidence. This paper assesses the outcomes of a novel inquiry-based paleoanthropology lab teaching human evolution to high-school students. The inquiry-based Be a Paleoanthropologist for a Day lab placed a dozen hominin skulls into the hands of high-school students. Upon measuring three variables of human evolution, students explain what they have observed and discuss findings. In the 2013/14 school year, 11 biology classes in 7 schools in the Greater New Orleans area participated in this lab. The interviewed teacher cohort unanimously agreed that the lab featuring hominin skull replicas and stimulating student inquiry was a pedagogically excellent method of delivering the subject of human evolution. First, the lab's learning path of transforming facts to data, information to knowledge, and knowledge to acceptance empowered students to themselves execute part of the science that underpins our understanding of deep time hominin evolution. Second, although challenging, the hands-on format of the lab was accessible to high-school students, most of whom were readily able to engage the lab's scientific process. Third, the lab's exciting and compelling pedagogy unlocked higher order thinking skills, effectively activating the cognitive, psychomotor and affected learning domains as defined in Bloom's taxonomy. Lastly, the lab afforded students a formative experience with a high degree of retention and epistemic depth. Further study is warranted to gauge the degree of these effects.

Abstract
Scientific data has been transformed into music in order to raise awareness in the non-scientific community. While the general public is nowadays familiar with the genetic code, there is still a lack of knowledge regarding epigenetic regulation. By making use of the binary nature of the methylome, we here describe a method that transforms methylation patterns into music. The resulting musical pieces show decent complexity and allow the audible recognition between music and underlying methylation state. This approach might therefore facilitate the recognition of complex methylation patterns and increase awareness for epigenetic regulation in the general public.

Abstract
The present study examined changes in university students' attitudes toward and knowledge of evolution measured by the previously validated Evolutionary Attitudes and Literacy Survey (EALS) in response to curricular content. Specifically, student responses on the survey were compared across an evolutionary psychology course, an introductory biology course with significant evolutionary content, and a political science course with no evolutionary content. To this end, 868 students were assessed at a large Midwestern U.S. university prior to and following completion of one of the three courses. A multiple group repeated measures confirmatory factor analysis (CFA) was conducted to examine latent mean differences in self-reported Evolution Knowledge/Relevance, Creationist Reasoning, Evolutionary Misconceptions, and Exposure to Evolution. A significant and notable increase in Knowledge/Relevance, as well as decreases in Creationist Reasoning and Evolutionary Misconceptions, was observed for the evolutionary psychology course, whereas the biology course demonstrated no change in Knowledge/Relevance and a significant increase in Evolutionary Misconceptions. The implications of these findings for evolution education are discussed.

Abstract
One goal of postsecondary education is to assist students in developing expert-level understanding. Previous attempts to encourage expert-level understanding of phylogenetic analysis in college science classrooms have largely focused on isolated, or "one-shot," in-class activities. Using a deliberate practice instructional approach, we designed a set of five assignments for a 300-level plant systematics course that incrementally introduces the concepts and skills used in phylogenetic analysis. In our assignments, students learned the process of constructing phylogenetic trees through a series of increasingly difficult tasks; thus, skill development served as a framework for building content knowledge. We present results from 5 yr of final exam scores, pre- and postconcept assessments, and student surveys to assess the impact of our new pedagogical materials on student performance related to constructing and interpreting phylogenetic trees. Students improved in their ability to interpret relationships within trees and improved in several aspects related to between-tree comparisons and tree construction skills. Student feedback indicated that most students believed our approach prepared them to engage in tree construction and gave them confidence in their abilities. Overall, our data confirm that instructional approaches implementing deliberate practice address student misconceptions, improve student experiences, and foster deeper understanding of difficult scientific concepts.

Abstract
Eyes have evolved many times, and arthropods and vertebrates share transcription factors for early development. Moreover, the photochemistry of vision in all eyes employs an opsin and the isomerization of a retinoid from the 11-cis to the all-trans configuration. The opsins, however, have associated with several different G proteins, initiating hyperpolarizing and depolarizing conductance changes at the photoreceptor membrane. Beyond these obvious instances of homology, much of the evolutionary story is one of tinkering, producing a great variety of morphological forms and variation within functional themes. This outcome poses a central issue in the convergence of evolutionary and developmental biology: what are the heritable features in the later stages of development that give natural selection traction in altering phenotypic outcomes? This paper discusses some results of evolutionary tinkering where this question arises and, in some cases, where the reasons for particular outcomes and the role of adaptation may not be understood. Phenotypic features include: the exploitation of microvilli in rhabdomeric photoreceptors for detecting the plane of polarized light; different instances of retinoid in the visual pigment; examples of the many uses of accessory pigments in tuning the spectral sensitivity of photoreceptors; selection of opsins in tuning sensitivity in aquatic environments; employing either reflection or refraction in the optics of compound eyes; the multiple ways of constructing images in compound eyes; and the various ways of regenerating 11-cis retinals to maintain visual sensitivity. Evolution is an irreversible process, but tinkering may recover some lost functions, albeit by new mutational routes. There is both elegance and intellectual coherence to the natural processes that produce such variety and functional complexity. But marginalizing the teaching of evolution in public education is a continuing social and political problem that contributes to the reckless capacity of humans to alter the planet without trying to understand how nature works.

Abstract
Acceptance of evolution by educators of prospective teachers remains superficially studied despite their role in having mentored schoolteachers whose weak support of evolution is known. Here, we contrast the views of New England educators of prospective teachers (n=62; 87% Ph. D./doctorate holders in 32 specializations) with those of the general faculty (n=244; 93% Ph.D./doctorate holders in 40 disciplines), both members of 35 colleges and universities, and with college students (n=827; subsample of the 35 institutions) who were polled on: (1) the controversy evolution vs. creationism vs. intelligent design (ID), (2) their understanding of how science/evolution works, and (3) their religiosity. The educators held intermediate positions in respect to the general faculty and the students: 94% of the general faculty, 75% of the educators, and 63% of the students said they accepted evolution openly; and 82% of the general faculty, 71% of the educators, and 58% of the students thought that evolution is definitely true. Only 3% of the general faculty in comparison to 19% of the educators and 24% of the students thought that evolution and creationism are in harmony. Although 93% of the general faculty, educators, and students knew that evolution relies on common ancestry, 26% of the general faculty, 45% of the educators, and 35% of the students did not know that humans are apes. Remarkably, 15% of the general faculty, 32% of the educators, and 35% of the students believed, incorrectly, that the origin of the human mind cannot be explained by evolution; and 30% of the general faculty, 59% of the educators, and 75% of the students were Lamarckian (=believed in inheritance of acquired traits). For science education: 96% of the general faculty, 86% of the educators, and 71% of the students supported the exclusive teaching of evolution, while 4% of the general faculty, 14% of the educators, and 29% of the students favored equal time to evolution, creationism and ID; note that 92% of the general faculty, 82% of the educators, and 50% of the students perceived ID as either not scientific and proposed to counter evolution based on false claims or as religious doctrine consistent with creationism. The general faculty was the most knowledgeable about science/evolution and the least religious (science index, SI=2.49; evolution index, EI= 2.49; and religiosity index, RI=0.49); the educators reached lower science/evolution but higher religiosity indexes than the general faculty (SI=1.96, EI=1.96, and RI=0.83); and the students were the least knowledgeable about science/ evolution and the most religious (SI=1.80, EI=1.60, and RI=0.89). Understanding of science and evolution were inversely correlated with level of religiosity, and understanding of evolution increased with increasing science literacy. Interestingly, ≈36% of the general faculty, educators and students considered religion to be very important in their lives, and 17% of the general faculty, 34% of the educators, and 28% of the students said they prayed daily. Assessing the perception of evolution by educators of prospective teachers vs. the general faculty and the students of New England, one of the historically most progressive regions in the U.S., is crucial for determining the magnitude of the impact of creationism and ID on attitudes toward science, reason, and education in science.

Abstract
While evolutionary theory follows from observable facts and logical inferences (Mayr, 1985), historically, the origin of novel inheritable variations was a major obstacle to acceptance of natural selection (Bowler, 1992; Bowler, 2005). While molecular mechanisms address this issue (Jablonka and Lamb, 2005), analysis of responses to the Biological Concept Inventory (BCI) (Klymkowsky et al., 2010), revealed that molecular biology majors rarely use molecular level ideas in their discourse, implying that they do not have an accessible framework within which to place evolutionary variation. We developed a "Socratic tutorial" focused on Muller's categorization of mutations' phenotypic effects (Muller, 1932). Using a novel vector-based method to analyzed students' essay responses, we found that a single interaction with this tutorial led to significant changes in thinking toward a clearer articulation of the effects of mutational change. We suggest that Muller's morphs provides an effective framework for facilitating student learning about mutational effects and evolutionary mechanisms.
