And not even bipedalism (that’s feet, right?)
From ScienceDaily:
What the last common ancestor between humans and African apes looked like has remained unclear. A new study now shows that important clues lie in the shoulder.
“Humans are unique in many ways. We have features that clearly link us with African apes, but we also have features that appear more primitive, leading to uncertainty about what our common ancestor looked like,” said Nathan Young, PhD, assistant professor at UC San Francisco School of Medicine and lead author of the study. “Our study suggests that the simplest explanation, that the ancestor looked a lot like a chimp or gorilla, is the right one, at least in the shoulder.”
Which should be an indictment of his whole field, but notice that no pop science medium treats it that way.
It appears, he said, that shoulder shape tracks changes in early human behavior such as reduced climbing and increased tool use.
So all we needed was a change in shoulder shape?
Who pays for this stuff anyhow?
Try. Buy. Own it. Live it.
