In biology, evolution is change in the inherited traits of a population of organisms through successive generations. Evolution has therefore been described as "descent with modification". Populations diverge from one another through a variety of mechanisms that lead to speciation. The most commonly understood mechanism occurs when populations become isolated into sub-populations that evolve independently and accumulate reproductive differences over time. These populations become species or speciate when they can no longer interbreed. Similarities among species suggest that all forms of life are descended from a common ancestor through a long series of these divergence events, stretching back in a tree of life that has grown over billions of years.
