Our own human nails evolved from claws. Many tree-climbing animals, like squirrels, have claws to clutch tree bark. Similarly, ancient primates that lived approximately 50 million years ago also had claws, new research has found. Teilhardina brandti, the oldest known primate, also had claws, called grooming claws.
Are human nails claws?
Nails separate primates from other mammals
Primates, including humans, have nails instead of claws as well as opposable thumbs. This gives humans more agile hands that allow us to grasp things better than other mammals.
Did ancient humans have claws?
But how, when and why we transitioned from claws to nails has been an evolutionary head-scratcher. Now, new fossil evidence shows that ancient primates – including one of the oldest known, Teilhardina brandti – had specialized grooming claws as well as nails.
