On human self-domestication, psychiatry, and eugenics

Area of Science:

• Evolutionary Biology
• Anthropology
• Bioethics

Background:

• The hypothesis of human self-domestication, comparing Homo sapiens to domesticated animals, has existed for over 150 years.
• Historically, this idea influenced psychiatry and Social Darwinism, leading to harmful eugenics practices like euthanasia and breeding programs.
• The debate on whether domestication influenced human anatomical changes since the Pleistocene is ongoing and depends on definitional criteria.

Purpose of the Study:

• To explore the historical and ethical implications of the human self-domestication hypothesis.
• To analyze the potential for misuse of scientific ideas in human biology, particularly the conflation of biological facts with moral imperatives.
• To propose objective terminology for human traits resembling domestication and consider modern genetic ethical challenges.

Main Methods:

• Historical analysis of philosophical and scientific discourse on human self-domestication.
• Examination of the link between the self-domestication concept and historical eugenics movements.
• Ethical analysis of modern genetic research and its potential societal impact.

Main Results:

• The human self-domestication hypothesis has been historically linked to pseudoscientific justifications for eugenics and discriminatory practices.
• Scientific ideas about human biology are susceptible to misuse, especially when moral conclusions are drawn from biological observations (naturalistic fallacy).
• Modern genetic advancements, particularly in psychiatric disorders, present new ethical dilemmas concerning genome alteration and unforeseen consequences.

Conclusions:

• The historical misuse of the human self-domestication concept serves as a cautionary tale regarding the interpretation of biological facts.
• Careful ethical consideration is crucial to prevent the repetition of past mistakes, especially in light of advancing genetic technologies.
• Human traits associated with domestication should be objectively described as adaptations, such as to sedentism, rather than through potentially misleading 'domestication-like' labels.
