Hereditary regression

Atavism
Evolutionary degeneration

Nature

Hereditary reappearance of features, usually physical, absent from parents and recent ancestors. Such features may be characteristic of more distant ancestors, or they may constitute a return to characteristics not typical of the species or race at all, but found in allied species or races having a common evolutionary ancestry (as in the case of strongly pronounced canine teeth in humans).

Claim

Hereditary regression is a critical issue that demands urgent attention. It threatens the very fabric of our genetic legacy, potentially leading to the resurgence of harmful traits and diseases. As we advance in genetics and medicine, we must prioritize understanding and addressing hereditary regression to safeguard future generations. Ignoring this problem could result in irreversible consequences for humanity, undermining decades of progress in health and well-being. We cannot afford to be complacent; action is imperative!

Counter-claim

Atavism does not necessarily represent a deterioration. It may be the re-emergence of valuable genetic characteristics of less-specialized progenitors. Many phenomena have been labelled atavisms which admit of other interpretations such as the consequences of arrested development due to malnutrition, a qualitative variation in some vestigial organ, or the predictable consequences of hybridization.
