Cattle’s Call of the Wild: Domestication may hold complex genetic tale
A new investigation of DNA that was obtained from modern cattle and from fossils of their ancient, wild ancestors challenges the idea that herding and farming groups in the Near East domesticated cattle about 11,000 years ago.

Fossils of a 4.1-million-year-old human ancestor in Ethiopia bolster the controversial idea that early members of our evolutionary family arose one species at a time rather than branching out into numerous species.
