Why human evolution should be a basic science for medicine and psychology students.

Area of Science:

• Evolutionary biology
• Psychology
• Medicine

Background:

• Human body and mind function and dysfunction are complex.
• Understanding disease vulnerability requires considering evolutionary perspectives.
• Traditional medical and psychology curricula often lack evolutionary biology.

Purpose of the Study:

• To examine aspects of human evolution relevant to understanding human body and mind.
• To highlight the importance of ultimate causations (adaptive significance) alongside proximate causations.
• To advocate for the inclusion of evolutionary biology in medical and psychology education.

Main Methods:

• Review of teaching experiences in medicine and psychology programs.
• Discussion of key evolutionary concepts: proximate vs. ultimate causation, phylogenetic constraints, evolutionary trade-offs, and socio-sexual selection.
• Analysis of how evolutionary principles explain human vulnerabilities and behaviors.

Main Results:

• Human vulnerabilities to disease stem from phylogenetic constraints, evolutionary trade-offs, and environmental mismatches.
• Pair-bonding and parent-offspring relationships are shaped by socio-sexual selection and evolutionary compromises.
• Evolutionary insights improve understanding of both functional and dysfunctional psychobiological mechanisms.

Conclusions:

• A comprehensive understanding of human body and mind necessitates integrating evolutionary biology.
• Evolutionary biology provides a powerful framework for clinical practice and research.
• Medical and psychology curricula should incorporate human phylogeny and evolutionary biology.
