Darwin’s Arsenal of Evidence and Theories

In his last chapter Darwin had many different pieces of evidence to support his claim. He pointed out that fossils from similar times, had more in common than fossils from vastly different times. For example, the different dinosaurs found are more similar to each other than they are to the animals we currently see on earth. He also argued that domestication was clear evidence for evolution, saying, “it is certain that (man) can largely influence the character of a breed by selecting, in each successive generation, individual differences so slight as to be quite inappreciable to an uneducated eye.” (Darwin, pg 488) Darwin also found that there were things in nature that didn’t make sense if an intelligence had created all life, such as flightless birds with wings essentially the same as other birds, “moles, which are habitually blind and have their eyes covered with skin” (Darwin, pg 493), and that a bee sting causes the bee to die. These makes mores sense in the context that all organisms come from an incomprehensible number of small changes that get passed down if that creature is able to reproduce. He also found it odd that many bone structures are similar between animals, such as the human hand and birds wings.

I found his most convincing argument to be all the imperfectness in nature. He also pointed out that the cross between a Zebra and a horse has stripes, which points to some common ancestor and an intermediate species for each, one with stripes and one without. This makes sense to me because if some higher being made all animals, different species being able to breed and create an infertile animal with properties of both doesn’t make much sense. I didn’t find his argument about animals sharing similar bone structures convincing because, if someone did make all the animals there’d be no reason they wouldn’t have created them like that.
