Abstract

Akey factor in evolution is reproduction, which is also a major concern in medicine. Evolutionists have proposed many theories and hypotheses to explain the low fertility rates of modern industrial societies, which are contrary to maximization of biological fitness. Given that childbirth is the most significant factor affecting reproductive fitness, it is likely that a variety of psychological modules related to childbirth behavior and intention evolved over time. Several evolutionary psychological modules have been proposed in relation to reproduction, including sexual desire, status-seeking, a need for nurturing, and the desire for children. Previously adaptive psychological modules may now be expressed maladaptively due to the discrepancy between the Environment of Evolutionary Adaptedness (EEA) and the environment of modern industrial society. Several evolutionary ecological factors influence childbirth intention in modern society, including individual personality factors, childhood life history experiences, and socioecological factors throughout reproductive life. By focusing on mental, social, and ecological factors, this review examines several hypothetical models relating to evolutionary psychological factors and childbirth decisions in modern industrial society, as well as a possible explanation for the low birth rate.

번식은 진화의 핵심 요인이면서, 동시에 의학의 중요한 관심사다. 특히 생물학적 적합도 최대화에 반하는 현대 산업 사회의 낮은 출산율에 대해 진화학자들이 다양한 이론과 가설을 제안했다. 출산은 번식 적합도에 미치는 가장 중요한 요인이기 때문에 출산 행동 및 의도와 관련된 다양한 심리적 모듈이 진화했을 것으로 추정된다. 성적 욕구, 사회적 지위 욕구, 양육 욕구, 출산 욕구(또는 아기 갈망)등이 번식과 관련된 진화 심리적 모듈로 제안되었다. 과거 진화적 적응 환경과 현대 산업 사회 환경의 불일치로 인해 과거에는 적응적이었던 심리적 모듈이 지금은 부적응적으로 발현될 수도 있다. 현대 사회에서 출산 의사에 영향을 미치는 진화생태학적 요인은 크게 개인의 성격적 요인, 유년기 생애사적 경험, 가임기 사회생태적 경험이 있다. 본 연구는 출산 의사 결정에 영향을 미치는 진화정신의학적 요인에 관한 가설과 모델을 고찰하고, 현대 산업 사회의 저출산 현상과 관련된 심리적 요인을 진화의학적 관점에서, 정신적, 사회적, 생태적 요인을 중심으로 개괄한다.
