Evolution By Natural Selection
Richard Owen an anatomist found that one of skulls Darwin brought back belonged to a Toxodon, a hippopotamus-sized relative of the South American capybara. Ornithologist John Gould announced that the Galapagos birds were differently adapted ground finches.

Darwin introduced transmutation and researched into the causes of extinction and accepted life as a branching tree. -
The Origin of Species
Darwin completed his book "On the Origin of Species by Means of Natural Selection" and was sold to trade on November 22, 1859. His book upset people, but he also gained supporters. Darwin perfected artificial selection experimenting with seeds in seawater by proving they can survive ocean crossings to start the process of speciation on islands. He also kept pigeon chicks to see if they were more like the ancestral rock dove than their own parents.
