Genetic Feedback and Human Population Regulation



Human population growth has been identified as a primary cause of ecologically destructive phenomena and, if left unchecked, will threaten the survivability of the human species. It has been demonstrated that genetic feedback is the mechanism by which species achieve ecological balance. The present analysis shows the applicability of this mechanism to human population regulation. In this model, the traits of behavior and culture are explained as following a four step process, similar to, and nested within genetic evolution. As species extinction is part and parcel of evolution, and environmental circumstances are changing rapidly, the population regulatory change that would take place on the genetic level of integration would be human extinction. However, the change on the cultural level, requiring a revision of the social contingency from “food production must be increased to feed a growing population” to “food production increases cause population increases,” would lead to human sustainability.
