Could our earliest ancestor walk upright 7 million years ago?
A tiny bump on a newly analyzed thigh bone from Sahelanthropus tchadensis may show this ancient ape walked upright — a trait long used to define what makes a human ancestor. But scientists have debated this species for decades. While its skull hinted at upright posture, others argued it was still tree-dwelling. This fossil adds fuel to the ongoing debate over when bipedal walking — and being "human" — truly began.🔍
