Walking upright.
You can make a case for all of them, but for three of them indirectly.

You can look at the pelvic bones and femur orientation in the hips. You can also look at the way the skull sits on the vertebra.
Chimpanzees have a skull that sits more downward, because they walk on all fours most of the time. While humans have skulls that sit more horizontally on the vertebra, which allows us to see out on the horizon more easily. We can do that because we stand on two feet.
I hope that helps.
