For the Chicago record label Atavistic, see Atavistic Records.An atavism is a real or supposed evolutionary throwback, such as traits reappearing which had disappeared generations ago. Atavisms occur because genes for previously existing phenotypical features are often preserved in DNA, even though the genes are not expressed in some or most of the organisms possessing them.
