I’m not quite sure what to make of this. The article is kind of interesting. A new species of Bos has been discovered in Buia, Eritrea dating to about one million years ago. Apparently the dig also yielded human remains. . The article goes on to say:
Although there is no evidence that early humans were actually herding early cattle 2.5 million years ago, the early humans and early cattle certainly shared the same landscape and beef was definitely on the menu all along, say researchers.
The article then goes on to talk about the relationship with African and Eurasian species of cattle and the similarity of the new species to those found circa 5,000 years ago on Saudi Arabian petroglyphs. The paper the article is based on is located here for those who have access. Hopefully, it goes into more details on the human/cattle interactions.
