Inferring evolutionary dynamics of mutation rates through the lens of mutation spectrum variation

There are many possible failure points in the transmission of genetic information that can produce heritable germline mutations. Once a mutation has been passed from parents to offspring for several generations, it can be difficult or impossible to identify its root cause; however, sometimes the nature of the ancestral and derived DNA sequences can provide mechanistic clues about a genetic change that happened hundreds or thousands of generations ago. Here, we review evidence that the sequence context 'spectrum' of germline mutagenesis has been evolving surprisingly rapidly over the history of humans and other species. We go on to discuss possible causal factors that might underlie rapid mutation spectrum evolution.

Paleopathology and children in the Andes: Local/situated biologies and future directions

In the decades since Verano (1997) published his foundational piece on Andean paleopathology, scholars have recognized the importance of the bioarchaeology of childhood. Yet, scholarship on ancient childhood in the Andes deemphasizes paleopathology. Nonadult paleopathological data are often employed in large-scale, biocultural studies focused on environmental or political adaptations; however, they can also elucidate children's individual lived experiences and roles in society. To generate culturally-meaningful paleopathological data, we must take a contextualized approach to our analyses and interpretations. Disparate use of chronological age in published datasets makes synthesis across studies problematic, and ethnohistorical and ethnographic data on Andean children demonstrate that developmental age categories, rather than chronological age ranges, are most appropriate. Further, paleopathological data can best inform our investigations when they are combined with related datasets such as those on sex, diet, activity, and mobility. With that in mind, we use the theoretical framework of "local biologies" (and the related "situated biologies"), where biology is viewed as heavily contingent on culturally-specific beliefs and practices and local physical, sociocultural, and political environments (Lock, 1993, 2001; Niewöhner and Lock, 2018). Local biologies approaches can enrich social bioarchaeology and paleopathology to by specifically situating children and their experiences within the ancient Andean world.

The Intersections of Identity and Politics in Archaeology

▪ Abstract  This paper traces the conjunction of two interrelated epistemic phenomena that have begun to shape the discipline since the early 1990s. The first entails theorizing social identity in past societies: specifically, how social lives are inscribed by the experiences of gender, ethnicity, sexuality, and so on. The other constitutes the rise of a politicized and ethical archaeology that now recognizes its active role in contemporary culture and is enunciated through the discourses of nationalism, sociopolitics, postcolonialism, diaspora, and globalism. Both trends have been tacitly shaped by anthropological and social theory, but they are fundamentally driven by the powerful voices of once marginalized groups and their newfound place in the circles of academic legitimacy. I argue that our disciplinary reticence to embrace the politics of identity, both in our investigations of the past and our imbrications in the present, has much to do with archaeology's lack of reflexivity, both personal and disciplinary, concurrent with its antitheoretical tendencies. The residual force of the latter should not be underestimated, specifically in regard to field practices and the tenacity of academic boundaries.
