Fingerprints

July 3, 2020 by J.B.

Chimpanzee hands are remarkably similar to our own, from their ability to grasp and use tools to their unique fingerprints. While the exact function of a fingerprint’s various whirls, loops, and arches is still unclear, it’s thought that they might increase grip on some surfaces or improve tactile perception. Scientists have yet to specifically examine the grooming-with-a-chopstick origin theory. As far as I know, koalas are the only animals other than primates to have them – a cool example of convergent evolution.
