So there's this new African fossil foot, right? Pretty much a normal thing to find in Africa, right?
And guess what — this new species may have spent more time in trees than on the ground!
It's 3.4 million years old, found in Ethiopia, and appears to put an end to the argument over whether there was only a single line of hominins.
That's not all, either: the newfound foot also had evolved a distinctive mode of locomotion, which is being called “equivocal.”
Meaning it clung to the trees and never adapted to terrestrial mobility outright.
This means that there was at least a bipedal line (stemming from Lucy) and a arboreal line that extended the Ardi line a million years past what we thought. A ground walker and a tree climber.
And if all of this is accurate, we know which one won out in the end.
