An adolescent female Tyrannosaurus rex died 68 million years ago, but its bones still contain intact soft tissue, including the oldest preserved proteins ever found, scientists say.

And a comparison of the protein's chemical structure to a slew of other species showed an evolutionary link between T. rex and chickens, bolstering the idea that birds evolved from dinosaurs.

Savannah chimpanzees, which can make weapons to hunt other primates for meat, can also seek refuge in caves, much like our earliest human ancestors.
