My Year of Darwin 10/25/2014: Darwin calls upon natural experiments

 Charles Darwin

"By considering the nature of the plants or animals which have struggled successfully with the indigines of any country, and have there become naturalised, we can gain some crude idea in what manner some of the natives would have had to be modified, in order to have gained an advantage over the other natives; and we may, I think, at least safely infer that diversification of structure, amounting to new generic differences, would have been profitable to them." Charles Darwin, Origin of Species 1st edition (on Kindle)

Origins is a masterpiece for the lines of evidence Darwin uses to back up his arguments. We have seen analogy (using artificial selection to show the ability of organisms to be shaped) and experimentation (experimentally sown patches with different densities and composition of plants).
