Document Summary
Caught malaria and had a revelation: darwin"s origin, all organisms evolved from a common ancestor. This was descent with modification: mechanism was natural selection, reception, descent with modification from a common ancestor was widely accepted soon after publication, natural selection was universally rejected for 50-60 years. Seemed to reject religious belief: thought earth wasn"t old enough for natural selection to create diversity today, no understanding of inheritance. Fossil record - any trace of an organism that lived in the past. Irish elk - found fossil, and realized it was an extinct species. People say a useless wing would not be preserved by natural selection in evolution: they serve other purposes. Wing assisted incline running: homology, analogous structures are structures that are similar but do not have a common ancestor and arise independently, homology, structural homology: structure is homologous: shares some common ancestor, definition.
