Charles Darwin- The Premise

Darwin's Theory is the widely held notion that all life is related and has descended from a common ancestor, the birds and the bananas, the fishes and the flowers are all related. Darwin's general theory says the development of life from non-life and stresses naturalistic, "descent with modification". That is complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism's genetic code, the mutations are preserved because they aid survival.
