What does atavism mean?

What is atavism and example?
In social sciences, atavism is the tendency of reversion. For example, people in the modern era reverting to the ways of thinking and acting of a former time. The word atavism is derived from the Latin atavus—a great-great-great-grandfather or, more generally, an ancestor.
What is atavistic in criminology?
Atavistic form is a historical approach used to explain criminal behaviour, which is based on the biological factors. This explanation was proposed by Lombroso in the 1870s and suggests that some people are born with a criminal personality (e.g. it is innate) that is a throwback to a previous more primitive ancestor.

Where did the term atavistic regression come from?
Meares coined his term from the English atavism, which is derived from the Latin atavus, meaning a great-grandfather’s grandfather and, thus, more generally, an ancestor. As used by Meares, for example, his 1960 work A System of Medical Hypnosis, the term “atavistic regression” is used to denote the tendency to revert to ancestral type:
What is atavism?
The term atavism is usually used to express the recurrence or reappearance of certain ‘primitive’ traits, physical or psychical, which presumably match those of an ancestral form.
Does atavism disappear in later development in animals?
These features normally disappear in later development, but it may not happen if the animal has an atavism. In biology, an atavism is a modification of a biological structure whereby an ancestral genetic trait reappears after having been lost through evolutionary change in previous generations.
How are Haeckel’s recapitulation theory and atavism related?
The same notions of atavisms were used by social Darwinists, who claimed that inferior races displayed atavistic traits, and represented more primitive traits than other races. Both atavism’s and Ernst Haeckel ‘s recapitulation theory are related to evolutionary progress, as development towards a greater complexity and a superior ability.
