WebbEvolution is a biological process. It is how living things change over time and how new species develop. The theory of evolution explains how evolution works, and how living and extinct things have come to be the way they are. The theory of evolution is a very important idea in biology.

Over time, inherited modified traits become dominant in the population, and a new species may emerge.

WebbEvolutionary theory predicts that peripheral populations in a species' range are likely to contain lower genetic diversity and higher genetic differentiation due to greater distance and smaller effective population size relative to more central populations (Eckert et al., 2008; Wulff, 1950 ).
