WebOct 11, 2024 · Human epidemiological studies have repeatedly linked adverse intrauterine and early postnatal events with subsequent obesity and metabolic disease as well as higher risk of a number of common mental health conditions—a phenomenon termed “fetal programming” ( Barker, 1990) or developmental origins of disease ( Gluckman and … Phenotypic variation (due to underlying heritable genetic variation) is a fundamental prerequisite for evolution by natural selection. It is the living organism as a whole that contributes (or not) to the next generation, so natural selection affects the genetic structure of a population indirectly via the contribution of phenotypes. Without phenotypic variation, there would be no evolution by natural selection.
