Is Darwinian Evolution Fact Or Theory But does this undermine Charles Darwin’s theory of evolution by natural selection. Darwin would have loved it. In fact to cover the possibility that acquired characters might be inherited, he. Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.Different characteristics tend to exist within any given population as a result of mutation, genetic recombination
