Of Eggplant, Ham, and Identity
In his much-anthologized “Tres cosas me tienen preso,” the Spanish poet Baltasar del Alcázar (1530–1606) compares a dish of ham, eggplant, and cheese to the beautiful Inés, and finds her wanting. While the poem can be read as a comic conflation of sex and food as dueling human appetites, here I suggest that the cultural connotations of ham (a quintessential Christian marker in Renaissance Spain), eggplant (a food strongly associated with the Musl…
Siberian genetic diversity reveals complex origins of the Samoyedic‐speaking populations
Objectives We examined autosomal genome‐wide SNPs and Y‐chromosome data from 15 Siberian and 12 reference populations to study the affinities of Siberian populations, and to address hypotheses about the origin of the Samoyed peoples. Methods Samples were genotyped for 567 096 autosomal SNPs and 147 Y‐chromosome polymorphic sites. For several analyses, we used 281 093 SNPs from the intersection of our data with publicly available ancient Siberian …
The Simons Genome Diversity Project
Here we report the Simons Genome Diversity Project data set: high quality genomes from 300 individuals from 142 diverse populations. These genomes include at least 5.8 million base pairs that are not present in the human reference genome. Our analysis reveals key features of the landscape of human genome variation, including that the rate of accumulation of mutations has accelerated by about 5% in non-Africans compared to Africans since divergenc…
Ancient human genomes suggest three ancestral populations for present-day Europeans
Great ape genetic diversity and population history
High-coverage sequencing of 79 (wild and captive) individuals representing all six non-human great ape species has identified over 88 million single nucleotide polymorphisms providing insight into ape genetic variation and evolutionary history and enabling comparison with human genetic diversity. In an effort to provide insights into great ape genetic variation, the authors sequence 79 wild- and captive-born individuals from across all six great …
No Evidence from Genome-wide Data of a Khazar Origin for the Ashkenazi Jews
The origin and history of the Ashkenazi Jewish population have long been of great interest, and advances in high-throughput genetic analysis have recently provided a new approach for investigating these topics. We and others have argued on the basis of genome-wide data that the Ashkenazi Jewish population derives its ancestry from a combination of sources tracing to both Europe and the Middle East. It has been claimed, however, through a reanalys…

Genetic evidence for archaic admixture in Africa
A long-debated question concerns the fate of archaic forms of the genus Homo : did they go extinct without interbreeding with anatomically modern humans, or are their genes present in contemporary populations? This question is typically focused on the genetic contribution of archaic forms outside of Africa. Here we use DNA sequence data gathered from 61 noncoding autosomal regions in a sample of three sub-Saharan African populations (Mandenka, Bi…
Increased Resolution of Y Chromosome Haplogroup T Defines Relationships among Populations of the Near East, Europe, and Africa
Increasing phylogenetic resolution of the Y chromosome haplo-group tree has led to finer temporal and spatial resolution for studies of human migration. Haplogroup T, initially known as K2 and defined by mutation M70, is found at variable frequencies across West Asia, Africa, and Europe. While several SNPs were recently discovered that extended the length of the branch leading to haplogroup T, only two SNPs are known to mark internal branches of …
New binary polymorphisms reshape and increase resolution of the human Y chromosomal haplogroup tree
Markers on the non-recombining portion of the human Y chromosome continue to have applications in many fields including evolutionary biology, forensics, medical genetics, and genealogical reconstruction. In 2002, the Y Chromosome Consortium published a single parsimony tree showing the relationships among 153 haplogroups based on 243 binary markers and devised a standardized nomenclature system to name lineages nested within this tree. Here we pr…
Distribution of Y chromosomes among native North Americans
In this study, 231 Y chromosomes from 12 populations were typed for four diagnostic single nucleotide polymorphisms (SNPs) to determine haplogroup membership and 43 Y chromosomes from three of these populations were typed for eight short tandem repeats (STRs) to determine haplotypes. These data were combined with previously published data, amounting to 724 Y chromosomes from 26 populations in North America, and analyzed to investigate the geograp…

European ACP1*C Allele Has Recessive Deleterious Effects on Early Life Viability
The acid phosphatase locus (ACP1) is a classical polymorphism that has been surveyed in hundreds of human populations worldwide. Among individuals of European ancestry, the ACP1*C allele occurs with an average frequency of approximately 0.05, whereas it is nearly absent in all other human populations. It has been hypothesized that this allele is maintained by overdominant selection among European populations. Here, we analyze ACP1 protein polymor…
An Indian trader in ancient Bali
DNA analysis of a tooth found with imported pottery in Bali offers a strong possibility of the presence of a trader of Indian extraction in the late first millennium BC
Andres Laguna y el humanismo medico
In the final sentence of Andrés Laguna y el humanismo médico, the author writes: "We are now able to affirm with the necessary rigor that Andrés Laguna ought to be placed among the great medical humanists of sixteenth-century Europe" (Andrés Laguna, p. 298). Whether either of these books succeeds in accomplishing this objective is questionable. Although exhaustively researched and rigorously structured, they suffer from an unfortunate lack of wit…
High Levels of Y-Chromosome Differentiation among Native Siberian Populations and the Genetic Signature of a Boreal Hunter-Gatherer Way of Life
We examined genetic variation on the nonrecombining portion of the Y chromosome (NRY) to investigate the paternal population structure of indigenous Siberian groups and to reconstruct the historical events leading to the peopling of Siberia. A set of 62 biallelic markers on the NRY were genotyped in 1432 males representing 18 Siberian populations, as well as nine populations from Central and East Asia and one from European Russia. A subset of the…
The Human Y Chromosome Haplogroup Tree
In this review we discuss the recent construction of a highly resolved tree of the nonrecombining portion of the Y chromosome (NRY), and the development of a cladistic nomenclatural system to name the resulting haplogroups. This phylogenetic gene tree comprises 18 major haplogroups that are defined by 48 binary polymorphisms. We also present results from a phylogeographic analysis of NRY haplogroups in a global sample of 2007 males, as well as fr…
Y chromosome markers and trans-Bering Strait dispersals
Five polymorphisms involving two paternally inherited loci were surveyed in 38 world populations (n = 1,631) to investigate the origins of Native Americans. One of the six Y chromosome combination haplotypes (1T) was found at relatively high frequencies (17.8-75.0%) in nine Native American populations (n = 206) representing the three major linguistic divisions in the New World. Overall, these data do not support the Greenberg et al. (1986) tripar…
