DNA study suggests ‘climate event’ contributed to collapse of empires

The keeping of livestock began in the Ancient Near East and underpinned the emergence of complex economies and then cities. Subsequently, it is there that the world's first empires rose and fell. Now, ...

Ancient genomics pinpoint origin and rapid turnover of cattle in the Fertile Crescent

Bronze Age people transported bulls from the Indus Valley region to breed cattle across West Asia and East Africa, starting about 4,000 years ago to combat increasing aridity, scientists reported on Thursday.Bronze Age people transported bulls from the Indus Valley region to breed cattle across West Asia and East Africa, starting about 4,000 years ago to combat increasing aridity, scientists reported on

Indus Valley bulls sired West Asia stock | Deccan Herald

Cattle were domesticated ∼10,000 years ago, but analysis of modern breeds has not elucidated their origins. Verdugo et al. performed genome-wide analysis of 67 ancient Near Eastern Bos taurus DNA samples. Several populations of ancient aurochs were progenitors of domestic cows. These genetic lineages mixed ∼4000 years ago in a region around the Indus Valley. Interestingly, mitochondrial analysis indicated that genetic material likely derived from arid-adapted Bos indicus (zebu) bulls was introduced by introgression. Science , this issue p. [173][1] Genome-wide analysis of 67 ancient Near Eastern cattle, Bos taurus, remains reveals regional variation that has since been obscured by admixture in modern populations. Comparisons of genomes of early domestic cattle to their aurochs progenitors identify diverse origins with separate introgressions of wild stock. A later region-wide Bronze Age shift indicates rapid and widespread introgression of zebu, Bos indicus, from the Indus Valley. This process was likely stimulated at the onset of the current geological age, ~4.2 thousand years ago, by a widespread multicentury drought. In contrast to genome-wide admixture, mitochondrial DNA stasis supports that this introgression was male-driven, suggesting that selection of arid-adapted zebu bulls enhanced herd survival. This human-mediated migration of zebu-derived genetics has continued through millennia, altering tropical herding on each continent. [1]: /lookup/doi/10.1126/science.aav1002
