Darwin's theory of evolution by Natural Selection
That biological types or species do not have a fixed, static existence but exist in permanent states of change and flux
That all life, biological considered, takes the from of a struggle to exist- more exactly, to exist and produce the greatest number offspring
That this struggle for existence culls out those organisms less well adapted to any particular ecology and allow those better adapted to flourish
Process called Natural Selection
That the genetic variation ultimately producing increased survivability are random and not cause by God or by the organism's own striving for perfection
That natural selection, development and evolution requires enormously long periods of time, so long. in fact that the everyday experience of human beings provide them with no ability to interpret such histories
