Ancient DNA analyses bring to life the 11,000-year intertwined genomic history of sheep and humans

The rise of pastoralist peoples in the Eurasian steppes and their westward spread some 5,000 years ago may have been fueled by sheep herding and people exploiting their milk. As early as 8,000 years ago the team found evidence that farmers were deliberately selecting their flocks — for example, for the genes coding for coat color. Sheep have been intertwined with human livelihoods for over 11,000 years. As well as meat, their domestication led to humans being nourished by their protein-rich milk and clothed by warm, water-resistant fabrics made from their wool. Now, a team of geneticists has deciphered the prehistoric cultural trajectory of this species by analyzing 118 genomes recovered from archaeological bones dating across 12 millennia and stretching from Mongolia to Ireland. …read more
