What made humans ‘the fat primate’? Changes in DNA packaging curbed our body’s ability to turn ‘bad’ fat into ‘good’ fat 

How did humans get to be so much fatter than our closest primate relatives, despite sharing 99% of the same DNA? A new study suggests that part of the answer may have to do with an ancient molecular shift in how DNA is packaged inside fat cells, which curbed our body’s ability to turn ‘bad’ white fat into ‘good’ brown fat.

Researchers: Tools from 2.6 million years ago have been found 

Researcher: “By 2.6 million years ago, they were beginning to understand the relationship between the folk physics of where to strike something, and how hard to hit it, and what angles to select,” … Well, you have to start somewhere.

Paleontologist: Humans walked on two legs from the beginning | Uncommon Descent

Carol Ward: It seems to be a behavior that was present in some of the earliest members of our branch of the family tree. It represented what was really the initial major adaptive change from any apelike creature that came before us.
