Iron Age origins of European Alpine dairy farming

Chemical analysis of organic residues from pottery reveals lipids

Dairy produce from the high Alps is today of enormous economic and cultural importance to the region. The recent history of dairy farming is well-documented, but there is very little in the way of archaeological evidence to attest to its origins. Transhumance (seasonal migration of livestock between pastures) leaves few traces, and the problem is compounded by acidic soils that lead to the deterioration of faunal remains. Continue reading

No Neanderthal-derived Y-chromosomes in modern population

Evidence found of genetic incompatibility

An open access study published in The American Journal of Human Genetics has found no evidence of Neanderthal introgression into modern male Y-chromosome despite it being elsewhere in the modern genome. The study is the first in which a Neanderthal Y-chromosome has been sequenced as all the Neanderthal individuals previously sequenced to 0.1x coverage were women. Women do not have a Y-chromosome, so men inherit their Y-chromosomal DNA exclusively from their fathers. The researchers sequenced the Y-chromosome from a male Neanderthal from the El Sidrón cave site in northern Spain, dating to 49,000 years ago. Continue reading
