Fun Fact: Atavism

Fun facts about evolution

While life has been evolving for eons, old traits can reappear after being absent when one species evolved into another. This is called an atavism, and it’s commonly nicknamed “an evolutionary throw-back”. For example in extremely rare cases biologists have discovered hind legs in whales, hind fins in dolphins, extra toes on horses, and teeth in chickens. An example found in humans are vestigial tails, and large teeth.
