The term "atavism" is used to describe the phenomenon of evolutionary regression or the reappearance of ancestral traits in an organism. It refers to the occurrence of characteristics in an individual that are not present in their immediate ancestors but were present in their distant ancestors. This phenomenon can be observed both in morphological traits, such as physical features, and in behavioral traits. Atavism is a result of genetic variations and can be seen in various species, including humans. It serves as a reminder of the complex and interconnected nature of evolutionary processes, highlighting the continuous influence of genetic information from previous generations.
