'''Atavisms''' are traits of ancient ancestors that were [[reproductive success|reproductively successful]] in the ancient ancestor's past environment, showing up in modern day offspring. These ancient ancestral traits may or may not be advantageous to have in modern times. In order for a trait to be considered an atavism the child's parents can't have the trait and neither can recent ancestors. The most well known form of atavism is being born one race but having the traits of another due to ancient ancestors being a different race than the current offspring's. | '''Atavisms''' are traits of ancient ancestors that were [[reproductive success|reproductively successful]] in the ancient ancestor's past environment, showing up in modern day offspring.
