Leaping Ancestors!

A 52-million-year-old ankle fossil suggests that some of the earliest primates were adept leapers. The #NSF-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, when it was previously thought that the earliest primates crept along small twigs slowly.
