Abstract
An intense debate concerning the nature and mode of Neolithic transition in Europe has long received much attention. Recent publications of paleogenetic analyses focusing on ancient European farmers from Central Europe or the Iberian Peninsula have greatly contributed to this debate, providing arguments in favor of major migrations accompanying European Neolithization and highlighting noticeable genetic differentiation between farmers associated with two archaeologically defined migration routes: the Danube valley and the Mediterranean Sea. The aim of the present study was to fill a gap with the first paleogenetic data of Neolithic settlers from a region (France) where the two great currents came into both direct and indirect contact with each other. To this end, we analyzed the Gurgy 'Les Noisats' group, an Early/Middle Neolithic necropolis in the southern part of the Paris Basin. Interestingly, the archaeological record from this region highlighted a clear cultural influence from the Danubian cultural sphere but also notes exchanges with the Mediterranean cultural area. To unravel the processes implied in these cultural exchanges, we analyzed 102 individuals and obtained the largest Neolithic mitochondrial gene pool so far (39 HVS-I mitochondrial sequences and haplogroups for 55 individuals) from a single archaeological site from the Early/Middle Neolithic period. Pairwise FST values, haplogroup frequencies and shared informative haplotypes were calculated and compared with ancient and modern European and Near Eastern populations. These descriptive analyses provided patterns resulting from different evolutionary scenarios; however, the archaeological data available for the region suggest that the Gurgy group was formed through equivalent genetic contributions of farmer descendants from the Danubian and Mediterranean Neolithization waves. However, these results, that would constitute the most ancient genetic evidence of admixture between farmers from both Central and Mediterranean migration routes in the European Neolithization debate, are subject to confirmation through appropriate model-based approaches.

Major transitions in human evolution revisited: a tribute to ancient DNA. J Hum Evol 2014; 79:4-20.

Abstract
The origin and diversification of modern humans have been characterized by major evolutionary transitions and demographic changes. Patterns of genetic variation within modern populations can help with reconstructing this ∼200 thousand year-long population history. However, by combining this information with genomic data from ancient remains, one can now directly access our evolutionary past and reveal our population history in much greater detail. This review outlines the main recent achievements in ancient DNA research and illustrates how the field recently moved from the polymerase chain reaction (PCR) amplification of short mitochondrial fragments to whole-genome sequencing and thereby revisited our own history. Ancient DNA research has revealed the routes that our ancestors took when colonizing the planet, whom they admixed with, how they domesticated plant and animal species, how they genetically responded to changes in lifestyle, and also, which pathogens decimated their populations. These approaches promise to soon solve many pending controversies about our own origins that are indecipherable from modern patterns of genetic variation alone, and therefore provide an extremely powerful toolkit for a new generation of molecular anthropologists.

Abstract
Samples of 100 random healthy unrelated Iraqi male persons from the Arab ethnic group of Iraqi population were collected for mtDNA coding region sequencing by using the Sanger technique and to establish the degree of variation characteristic of a fragment. Portion of coding region encompassing positions 11,719-12,184 was amplified in accordance with the Anderson reference sequence. PCR products were purified by EZ-10 spin column then sequenced and detected by using the ABI 3130xL DNA Analyzer. This is to intend the detection of polymorphisms of mtDNA. Four new polymorphic positions 11,741, 11,756, 11,878, and 12,133 are described which may be suitable in the future to be the sources for human identification purpose in Iraq. The obtained data can be used to identify variable nucleotide positions characterized by frequent occurrence most promising for identification variants. The calculated value GD = 0.95 and RMP = 0.048 of the genetic diversity should be understood as high in the context of coding function of the analysed DNA fragment. The relatively high gene diversity and a relatively low random match probability were observed in this study.

Abstract
The processes that shaped modern European mitochondrial DNA (mtDNA) variation remain unclear. The initial peopling by Palaeolithic hunter-gatherers ~42,000 years ago and the immigration of Neolithic farmers into Europe ~8000 years ago appear to have played important roles but do not explain present-day mtDNA diversity. We generated mtDNA profiles of 364 individuals from prehistoric cultures in Central Europe to perform a chronological study, spanning the Early Neolithic to the Early Bronze Age (5500 to 1550 calibrated years before the common era). We used this transect through time to identify four marked shifts in genetic composition during the Neolithic period, revealing a key role for Late Neolithic cultures in shaping modern Central European genetic diversity.

Abstract
Understanding the peopling history of Europe is crucial to comprehend the origins of modern populations. Of course, the analysis of current genetic data offers several explanations about human migration patterns which occurred on this continent, but it fails to explain precisely the impact of each demographic event. In this context, direct access to the DNA of ancient specimens allows the overcoming of recent demographic phenomena, which probably highly modified the constitution of the current European gene pool. In recent years, several DNA studies have been successfully conducted from ancient human remains thanks to the improvement of molecular techniques. They have brought new fundamental information on the peopling of Europe and allowed us to refine our understanding of European prehistory. In this review, we will detail all the ancient DNA studies performed to date on ancient European DNA from the Middle Paleolithic to the beginning of the protohistoric period.

Abstract
Neolithic processes underlying the distribution of genetic diversity among European populations have been the subject of intense debate since the first genetic data became available. However, patterns observed in the current European gene pool are the outcome of Paleolithic and Neolithic processes, overlaid with four millennia of further developments. This observation encouraged paleogeneticists to contribute to the debate by directly comparing genetic variation from the ancient inhabitants of Europe to their contemporary counterparts. Pre-Neolithic and Neolithic paleogenetic data are becoming increasingly available for north and northwest European populations. Despite the numerous problems inherent in the paleogenetic approach, the accumulation of ancient DNA datasets offers new perspectives from which to interpret the interactions between hunter-gatherer and farming communities. In light of information emerging from diverse disciplines, including recent paleogenetic studies, the most plausible model explaining the movement of Neolithic pioneer groups in central Europe is that of leapfrog migration.

Abstract
The impact of the Neolithic dispersal on the western European populations is subject to continuing debate. To trace and date genetic lineages potentially brought during this transition and so understand the origin of the gene pool of current populations, we studied DNA extracted from human remains excavated in a Spanish funeral cave dating from the beginning of the fifth millennium B.C. Thanks to a "multimarkers" approach based on the analysis of mitochondrial and nuclear DNA (autosomes and Y-chromosome), we obtained information on the early Neolithic funeral practices and on the biogeographical origin of the inhumed individuals. No close kinship was detected. Maternal haplogroups found are consistent with pre-Neolithic settlement, whereas the Y-chromosomal analyses permitted confirmation of the existence in Spain approximately 7,000 y ago of two haplogroups previously associated with the Neolithic transition: G2a and E1b1b1a1b. These results are highly consistent with those previously found in Neolithic individuals from French Late Neolithic individuals, indicating a surprising temporal genetic homogeneity in these groups. The high frequency of G2a in Neolithic samples in western Europe could suggest, furthermore, that the role of men during Neolithic dispersal could be greater than currently estimated.

Abstract
The first farmers from Central Europe reveal a genetic affinity to modern-day populations from the Near East and Anatolia, which suggests a significant demographic input from this area during the early Neolithic. In Europe, the Neolithic transition (8,000–4,000 b.c.) from hunting and gathering to agricultural communities was one of the most important demographic events since the initial peopling of Europe by anatomically modern humans in the Upper Paleolithic (40,000 b.c.). However, the nature and speed of this transition is a matter of continuing scientific debate in archaeology, anthropology, and human population genetics. To date, inferences about the genetic make up of past populations have mostly been drawn from studies of modern-day Eurasian populations, but increasingly ancient DNA studies offer a direct view of the genetic past. We genetically characterized a population of the earliest farming culture in Central Europe, the Linear Pottery Culture (LBK; 5,500–4,900 calibrated b.c.) and used comprehensive phylogeographic and population genetic analyses to locate its origins within the broader Eurasian region, and to trace potential dispersal routes into Europe. We cloned and sequenced the mitochondrial hypervariable segment I and designed two powerful SNP multiplex PCR systems to generate new mitochondrial and Y-chromosomal data from 21 individuals from a complete LBK graveyard at Derenburg Meerenstieg II in Germany. These results considerably extend the available genetic dataset for the LBK (n = 42) and permit the first detailed genetic analysis of the earliest Neolithic culture in Central Europe (5,500–4,900 calibrated b.c.). We characterized the Neolithic mitochondrial DNA sequence diversity and geographical affinities of the early farmers using a large database of extant Western Eurasian populations (n = 23,394) and a wide range of population genetic analyses including shared haplotype analyses, principal component analyses, multidimensional scaling, geographic mapping of genetic distances, and Bayesian Serial Simcoal analyses. The results reveal that the LBK population shared an affinity with the modern-day Near East and Anatolia, supporting a major genetic input from this area during the advent of farming in Europe. However, the LBK population also showed unique genetic features including a clearly distinct distribution of mitochondrial haplogroup frequencies, confirming that major demographic events continued to take place in Europe after the early Neolithic. The transition from a hunter–gatherer existence to a sedentary farming-based lifestyle has had key consequences for human groups around the world and has profoundly shaped human societies. Originating in the Near East around 11,000 y ago, an agricultural lifestyle subsequently spread across Europe during the New Stone Age (Neolithic). Whether it was mediated by incoming farmers or driven by the transmission of innovative ideas and techniques remains a subject of continuing debate in archaeology, anthropology, and human population genetics. Ancient DNA from the earliest farmers can provide a direct view of the genetic diversity of these populations in the earliest Neolithic. Here, we compare Neolithic haplogroups and their diversity to a large database of extant European and Eurasian populations. We identified Neolithic haplotypes that left clear traces in modern populations, and the data suggest a route for the migrating farmers that extends from the Near East and Anatolia into Central Europe. When compared to indigenous hunter–gatherer populations, the unique and characteristic genetic signature of the early farmers suggests a significant demographic input from the Near East during the onset of farming in Europe.

Abstract
Using established criteria for work with fossil DNA we have analysed mitochondrial DNA from 92 individuals from 18 locations in Denmark ranging in time from the Mesolithic to the Medieval Age. Unequivocal assignment of mtDNA haplotypes was possible for 56 of the ancient individuals; however, the success rate varied substantially between sites; the highest rates were obtained with untouched, freshly excavated material, whereas heavy handling, archeological preservation and storage for many years influenced the ability to obtain authentic endogenic DNA. While the nucleotide diversity at two locations was similar to that among extant Danes, the diversity at four sites was considerably higher. This supports previous observations for ancient Britons. The overall occurrence of haplogroups did not deviate from extant Scandinavians, however, haplogroup I was significantly more frequent among the ancient Danes (average 13%) than among extant Danes and Scandinavians (∼2.5%) as well as among other ancient population samples reported. Haplogroup I could therefore have been an ancient Southern Scandinavian type “diluted” by later immigration events. Interestingly, the two Neolithic samples (4,200 YBP, Bell Beaker culture) that were typed were haplogroup U4 and U5a, respectively, and the single Bronze Age sample (3,300–3,500 YBP) was haplogroup U4. These two haplogroups have been associated with the Mesolithic populations of Central and Northern Europe. Therefore, at least for Southern Scandinavia, our findings do not support a possible replacement of a haplogroup U dominated hunter-gatherer population by a more haplogroup diverse Neolithic Culture.

Abstract
Background Given the relative abundance of modern human DNA and the inherent impossibility for incontestable proof of authenticity, results obtained on ancient human DNA have often been questioned. The widely accepted rules regarding ancient DNA work mainly affect laboratory procedures, however, pre-laboratory contamination occurring during excavation and archaeological-/anthropological handling of human remains as well as rapid degradation of authentic DNA after excavation are major obstacles. Methodology/Principal Findings We avoided some of these obstacles by analyzing DNA from ten Viking Age subjects that at the time of sampling were untouched by humans for 1,000 years. We removed teeth from the subjects prior to handling by archaeologists and anthropologists using protective equipment. An additional tooth was removed after standard archaeological and anthropological handling. All pre-PCR work was carried out in a “clean- laboratory” dedicated solely to ancient DNA work. Mitochondrial DNA was extracted and overlapping fragments spanning the HVR-1 region as well as diagnostic sites in the coding region were PCR amplified, cloned and sequenced. Consistent results were obtained with the “unhandled” teeth and there was no indication of contamination, while the latter was the case with half of the “handled” teeth. The results allowed the unequivocal assignment of a specific haplotype to each of the subjects, all haplotypes being compatible in their character states with a phylogenetic tree drawn from present day European populations. Several of the haplotypes are either infrequent or have not been observed in modern Scandinavians. The observation of haplogroup I in the present study (<2% in modern Scandinavians) supports our previous findings of a pronounced frequency of this haplogroup in Viking and Iron Age Danes. Conclusion The present work provides further evidence that retrieval of ancient human DNA is a possible task provided adequate precautions are taken and well-considered sampling is applied.

Abstract
One of the largest skeletal series of the Upper Palaeolithic period from Predmostí was destroyed during the Second World War, but the study of this material continues up to the present. The discovery of Matiegka's original photographic documentation on glass plates [Velemínská et al., 2004. The use of recently re-discovered glass plate photo-documentation of those human fossil finds from Predmostí u Prerova destroyed during World War II. J. Nat. Mus. Nat. Hist. Ser. 173, 129-132] gives an opportunity to perform a new and detailed craniometric analysis of five adult skulls in their lateral projection. The craniometric data were analysed using specialised Craniometrics software, and the analysis included morphological and dimensional comparisons with current Central European norms. The aim of the study was not only to monitor the skull shape as a whole, but predominantly, to evaluate the size and shape of various parts of the splanchnocranium. The Upper Palaeolithic skulls are significantly longer, and male skulls are also higher than the current norms. The crania of anatomically modern humans are characterised by two general structural features: mid-lower facial retraction and neurocranial globularity. The height of the face of the Palaeolithic skulls corresponds to that of the current Central European population. The face has a markedly longer mandibular body (3-4 SD), while female mandibular rami are shorter. The skulls are further characterised by a smaller gonial angle, the increased steepness of the mandibular ramus, and the greater angle of the chin. These changes in the size and shape associated with anterior rotation of the face produce a strong protrusion of both jaws, but the sagittal inter-maxillary relationships remain unchanged. The observed facial morphology is similar to the Czech Upper Palaeolithic skulls from Dolní Vestonice. This study confirms the main diachronic changes between skulls of Upper Palaeolithic and present-day human populations.

Mummification by natural influences results in so-called natural mummies, whereas mummification induced by active (human) intervention results in so-called artificial mummies, although many cultures practiced burial rites, which to some degree involved both natural and artificial mummification. Since they are so uniquely well-preserved, mummies may give many insights into mortuary practices and burial rites. Specifically, the presence of soft tissues may expand the scope of paleopathological studies. Many recent mummy studies focus on the development and application of nondestructive methods for examining mummies, including radiography, CT-scanning with advanced three-dimensional visualizations, and endoscopic techniques, as well as minimally-destructive chemical, physical, and biological methods for, e.g., stable isotopes, trace metals, and DNA. This article discusses mummification and gives a presentation of various key mummy finds and a brief history of mummy studies. A description of the extant key technologies of natural and medical science that are applied in mummy studies is given; along with a discussion of some of the major results in terms of paleopathology. It is also shown how mummy studies have contributed much to the knowledge of the cultural habits and everyday life of past populations. Finally the impact of mummy studies on analyses of mortuary practices and cultural history is discussed.

Abstract
The last of the Danish Viking Kings, Sven Estridsen, died in a.d. 1074 and is entombed in Roskilde Cathedral with other Danish kings and queens. Sven's mother, Estrid, is entombed in a pillar across the chancel. However, while there is no reasonable doubt about the identity of Sven, there have been doubts among historians whether the woman entombed was indeed Estrid. To shed light on this problem, we have extracted and analysed mitochondrial DNA (mtDNA) from pulp of teeth from each of the two royals. Four overlapping DNA-fragments covering about 400bp of hypervariable region 1 (HVR-1) of the D-loop were PCR amplified, cloned and a number of clones with each segment were sequenced. Also a segment containing the H/non-H specific nucleotide 7028 was sequenced. Consensus sequences were determined and D-loop results were replicated in an independent laboratory. This allowed the assignment of King Sven Estridsen to haplogroup H; Estrid's sequence differed from that of Sven at two positions in HVR-1, 16093T-->C and 16304T-->C, indicating that she belongs to subgroup H5a. Given the maternal inheritance of mtDNA, offspring will have the same mtDNA sequence as their mother with the exception of rare cases where the sequence has been altered by a germ line mutation. Therefore, the observation of two sequence differences makes it highly unlikely that the entombed woman was the mother of Sven. In addition, physical examination of the skeleton and the teeth strongly indicated that this woman was much younger (approximately 35 years) at the time of death than the 70 years history records tell. Although the entombed woman cannot be the Estrid, she may well be one of Sven's two daughters-in-law who were also called Estrid and who both became queens.

Abstract
The Basque population has been considered an outlier in a large number of genetic studies, due to its hypothesized antiquity and greater genetic isolation. The present paper deals with an analysis of the mtDNA variability of the historical population of Aldaieta (VI-VII c. AD; Basque Country) which, together with genetic data existing for other prehistoric populations of the Basque Country (4,500-5,000 YBP), permits an appraisal of the hypotheses proposed for the origin of the genetic differentiation of the Basque population. Given that this is an aDNA study, application has been made both of standard precautions, to avoid contamination, and of authentication criteria (analysis of duplicates, replication in an independent laboratory, quantification of target DNA, sequencing and cloning of PCR products). The variability of the mtDNA haplogroups of the historical population of Aldaieta falls within the range of the present-day populations of Europe's Atlantic fringe, whereas the prehistoric populations of the Basque Country display clear differentiation in relation to all others. Consequently, we suggest that between 5,000-1,500 YBP approximately, there may have been gene flow amongst the western European populations that homogenised mtDNA lineages.

Abstract
Ancient DNA (aDNA) sequences, especially those of human origin, are notoriously difficult to analyze due to molecular damage and exogenous DNA contamination. Relatively few systematic studies have focused on this problem. Here we investigate the extent and origin of human DNA contamination in the most frequently used sources for aDNA studies, that is, bones and teeth from museum collections. To distinguish contaminant DNA from authentic DNA we extracted DNA from dog (Canis familiaris) specimens. We monitored the presence of a 148-bp human-specific and a 152-bp dog-specific mitochondrial DNA (mtDNA) fragment in DNA extracts as well as in negative controls. The total number of human and dog template molecules were quantified using real-time polymerase chain reaction (PCR), and the sequences were characterized by amplicon cloning and sequencing. Although standard precautions to avoid contamination were taken, we found that all samples from the 29 dog specimens contained human DNA, often at levels exceeding the amount of authentic ancient dog DNA. The level of contaminating human DNA was also significantly higher in the dog extracts than in the negative controls, and an experimental setup indicated that this was not caused by the carrier effect. This suggests that the contaminating human DNA mainly originated from the dog bones rather than from laboratory procedures. When cloned, fragments within a contaminated PCR product generally displayed several different sequences, although one haplotype was often found in majority. This leads us to believe that recognized criteria for authenticating aDNA cannot separate contamination from ancient human DNA the way they are presently used.

Abstract
Besides its obvious intrinsic value, knowledge of population history, and of the demographic and evolutionary changes that accompany it, has proven fundamental to address applied research in human genetics. In this review we place current European genetic diversity in the context of the global human genome diversity and review the evidence supporting a recent African origin of the Europeans. We then discuss the results and the interpretation of genetic studies attempting to quantify the relative importance of various gene flow processes, both within Europe and from Asia into Europe, focusing especially on the initial, Paleolithic colonization of the continent, and on later, Paleolithic postglacial and Neolithic dispersals. Finally, we discuss how knowledge of the patterns of genetic diversity in Europe, and of their inferred generating processes, can be extremely useful in planning health care and in biomedical research.

Abstract
The origins of the Etruscans, a non-Indo-European population of preclassical Italy, are unclear. There is broad agreement that their culture developed locally, but the Etruscans' evolutionary and migrational relationships are largely unknown. In this study, we determined mitochondrial DNA sequences in multiple clones derived from bone samples of 80 Etruscans who lived between the 7th and the 3rd centuries b.c. In the first phase of the study, we eliminated all specimens for which any of nine tests for validation of ancient DNA data raised the suspicion that either degradation or contamination by modern DNA might have occurred. On the basis of data from the remaining 30 individuals, the Etruscans appeared as genetically variable as modern populations. No significant heterogeneity emerged among archaeological sites or time periods, suggesting that different Etruscan communities shared not only a culture but also a mitochondrial gene pool. Genetic distances and sequence comparisons show closer evolutionary relationships with the eastern Mediterranean shores for the Etruscans than for modern Italian populations. All mitochondrial lineages observed among the Etruscans appear typically European or West Asian, but only a few haplotypes were found to have an exact match in a modern mitochondrial database, raising new questions about the Etruscans' fate after their assimilation into the Roman state.

Abstract
During the late Pleistocene, early anatomically modern humans coexisted in Europe with the anatomically archaic Neandertals for some thousand years. Under the recent variants of the multiregional model of human evolution, modern and archaic forms were different but related populations within a single evolving species, and both have contributed to the gene pool of current humans. Conversely, the Out-of-Africa model considers the transition between Neandertals and anatomically modern humans as the result of a demographic replacement, and hence it predicts a genetic discontinuity between them. Following the most stringent current standards for validation of ancient DNA sequences, we typed the mtDNA hypervariable region I of two anatomically modern Homo sapiens sapiens individuals of the Cro-Magnon type dated at about 23 and 25 thousand years ago. Here we show that the mtDNAs of these individuals fall well within the range of variation of today's humans, but differ sharply from the available sequences of the chronologically closer Neandertals. This discontinuity is difficult to reconcile with the hypothesis that both Neandertals and early anatomically modern humans contributed to the current European gene pool.

Abstract
The spectrum of postmortem damage in mitochondrial DNA was analyzed in a large data set of cloned sequences from ancient human specimens. The most common forms of damage observed are two complementary groups of transitions, termed "type 1" (adenine-->guanine/thymine-->cytosine) and "type 2" (cytosine-->thymine/guanine-->adenine). Single-primer extension PCR and enzymatic digestion with uracil-N-glycosylase confirm that each of these groups of transitions result from a single event, the deamination of adenine to hypoxanthine, and cytosine to uracil, respectively. The predominant form of transition-manifested damage varies by sample, though a marked bias toward type 2 is observed with increasing amounts of damage. The two transition types can be used to identify the original strand, light (L) or heavy (H), on which the initial damage event occurred, and this can increase the number of detected jumping-PCR artifacts by up to 80%. No bias toward H-strand-specific damage events is noted within the hypervariable 1 region of human mitochondria, suggesting the rapid postmortem degradation of the secondary displacement (D-loop) H strand. The data also indicate that, as damage increases within a sample, fewer H strands retain the ability to act as templates for enzymatic amplification. Last, a significant correlation between archaeological site and sample-specific level of DNA damage was detected.

Abstract
The increasingly obvious medical relevance of human genetic variation is fueling the development of a rich interface between medical genetics and the study of human genetic history. A key feature of this interface is a step increase in the size and diversity of genetic data sets, permitting a range of new questions to be addressed concerning our evolutionary history. Similarly, methodologies first developed to study genetic history are being tailored to address medical challenges, including mapping genes that influence diseases and variable drug reactions. In this paper we do not attempt a comprehensive review of human genetic history. Rather we briefly outline some of the complications and challenges in the study of human genetic history, drawing particular attention to new opportunities created by the explosive growth in genetic information and technologies. First we discuss the complexity of human migration and demographic history, taking both a genetic and archaeological perspective. Then we show how these apparently academic issues are becoming increasingly important in medical genetics, focusing on association studies, the common disease/common variant hypothesis, the evaluation of variable drug response, and inferences about gene function from patterns of genetic variation. Finally we describe some of the inferential approaches available for interpreting human genetic variation, focusing both on current limitations and future developments.

Abstract
Historical sources indicate that the evangelist Luke was born in Syria, died in Greece, and then his body was transferred to Constantinople, and from there to Padua, Italy. To understand whether there is any biological evidence supporting a Syrian origin of the Padua body traditionally attributed to Luke, or a replacement in Greece or Turkey, the mtDNA was extracted from two teeth and its control region was cloned and typed. The sequence determined in multiple clones is an uncommon variant of a set of alleles that are common in the Mediterranean region. We also collected and typed modern samples from Syria and Greece. By comparison with these population samples, and with samples from Anatolia that were already available in the literature, we could reject the hypothesis that the body belonged to a Greek, rather than a Syrian, individual. However, the probability of an origin in the area of modern Turkey was only insignificantly lower than the probability of a Syrian origin. The genetic evidence is therefore compatible with the possibility that the body comes from Syria, but also with its replacement in Constantinople.
