Steak Dinners Go Back 2.5 Million Years
A new fossil skull of a bull confirms that beef has been "what's
for dinner" since the dawn of humans.

THE GIST:


* A new early bull species shows that cattle and humans evolved
side-by-side.
* The fossil skull is a missing link between modern cattle and
their African ancestors.
* Early humans didn't herd cattle, but they most definitely hunted
them and ate them.


The discovery of a new "missing link" species of bull dating to a
million years ago in Eritrea pushes back the beef steak dinner to the
very dawn of humans and cattle.


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 telltale fossil is a skull with enormous horns that belongs to the
cattle genus Bos. It has been reassembled from over a hundred shards
found at a dig that also contains early human remains, said
paleontologist Bienvenido Martinez-Navarro of the Universitat Rovira i
Virgili in Tarragona, Spain. Martinez is the lead author of a paper
reporting the discovery in the February issue of the journal
Quaternary International.


"This means that the humans have been eating Bos since the beginnings
of the genus Homo," said Martinez, referring to the genus to which
humans belong.

Abstract


The origin of the genus Bos is a debated issue. It has traditionally
been linked with that of the genera Leptobos and Bison, two Eurasian
forms. The oldest record of Bos, B. primigenius, in Eurasia is at
Venosa-Notarchirico, Italy (not, vert, similar0.5 to 0.6 Ma). However,
the oldest published evidence of modern Bos is a skull fragment from
Asbole, Lower Awash Valley, Ethiopia (not, vert, similar0.6 to 0.8
Ma). This paper describes a new species, Bos buiaensis, from Buia,
Eritrea (1.0 Ma). B. buiaensis shows a combination of primitive
characters of the African Late Pliocene and Early Pleistocene form
Pelorovis sensu stricto and derived characters of B. primigenius. This
new finding demonstrates that Bos has been part of the human
ecological landscape since the beginning of the genus Homo in the
African Late Pliocene.

This is definitely intriguing. I like the "Gist" section of this post, summing up the info. Thanks for posting this!
