All living things have much in common, in their chemical composition, their germinal vesicles, their cellular structure and their laws of growth and reproduction. Therefore I should infer that probably all the organic beings which have ever lived on the earth have descended from some one primordial form.
Charles Darwin,
The Origin of Species, 1859
