Generally speaking, evolution is any process of growth, change or development. The evolutionary timeline outlines the major steps of evolution on Earth. An explanation as to how this evolution occurs is referred to as a theory of evolution, and while transmutation was accepted by a sizeable number of scientists before 1859, it was the publication of Charles Darwin's The Origin of Species which provided the first cogent mechanism by which evolutionary change could occur: his mechanism of Natural selection. It is worth noting that the mechanism (natural selection) is logically independent of the observation that evolution does indeed occur. Biological evolution results in populations of organisms which are more adapted to their current environment than previous populations. Since, in the long run, environments always change, if successive generations did not develop adaptations which allowed them to survive and reproduce, species would simply die out. Evolution therefore allows life, as expressed in a given genetic line, to persist over greater spans of time.
