Leaping ancestors!

A 52-million-year-old ankle fossil suggests that some of the earliest primates were adept leapers. National Science Foundation-funded researchers at Duke University examined the ankle joint from a chipmunk-sized creature. The team was surprised to find that these first primates were masters of leaping. It was previously thought that the earliest primates crept along small twigs slowly.
