Charles Darwin



Who was Charles Darwin?
Charles Darwin was................. born in Shrewsburry, Shropshire , England on 12 February 1809 at his family home,the mount. He was the fifth of six children of wealthy society doctor and financier Robert Darwin, and Susannah Darwin. He was the grandson of Erasmus Darwin on his father's side, and of Josiah Wedgwood on his mother's side. Also was an English Naturalist who established that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection.





What was the Theory of Natural Selection?
Natural selection is a natural law by which geneticallyheritable traits become more or less common in a population over successive generations. This selection in interaction with the production of variation, the possible genetic fixation process and possibly, in several cases, with little epigenetic process determine the evolution of the species.
