Neandertals disappeared from the fossil record around 40,000 bp, after a demographic history of small and isolated groups with high but variable levels of inbreeding, and episodes of interbreeding with other Paleolithic hominins. It is reasonable to expect that high levels of endogamy could be expressed in the skeleton of at least some Neandertal groups.
By analyzing 1772 Y chromosomes from 25 predominantly small urban locations, we found that different parts of the British Isles have sharply different paternal histories; the degree of population replacement and genetic continuity shows systematic variation across the sampled areas.
We describe the first dental proteomic profiles of Iron Age individuals (c2000‐1000 years B.P), collected from the site of Long Long Rak rock shelter (LLR) in northwest Thailand.
In 2015, a widespread group of geneticists (Mathieson et al. 2015) reported the first ancient DNA investigation of the full genome from 26 Anatolian skeletons, concluding that these belonged to a population that was the source of Europe’s first farmers.
Current approaches to mixture deconvolution of complex biological samples at times do not have the capability to resolve component contributors in DNA evidence. Additional short tandem repeat (STR) loci were sought that may improve the forensic genetic analysis of mixtures.
The idea that autistic symptoms are produced by an ‘extreme male brain’ warrants further examination. The concept of the ‘extreme male brain’ derives from scores on the Autism Spectrum Questionnaire (AQ) i.e. it is defined behaviourally rather than anatomically.
Who were the first Americans, where did they come from and how did they spread? The story is as thrilling as an adventure story—in fact, it is one.
To assess the timing, places of origin and extent of admixture between these components, we performed an analysis of the Y-chromosome haplogroup Q, which is the only Pan-American haplogroup and accounts for virtually all Native American Y chromosomes in Mesoamerica and South America.
We presented allele frequencies of 27 X-chromosomal short tandem repeats obtained from 352 unrelated individuals in Egypt.
In the Western Siberian arctic, permafrost mummies have been found in 12th to 13th century graves located in the Zeleny Yar (Z-Y) burial ground (66°19’4.54″С; 67°21’13.54″В). In 2013–2016, we were fortunate to be able to excavate that cemetery..
