Document Summary
Darwin didn"t discover natural selection, but artificial selection. Accumulation of organisms over time, where there are some benefit to the species. Idea of the survival of the fittest. Survive the best, and find a mate to pass on offspring. Charles darwin used natural selection to explain many of the features/adaptations of organisms. However, there were no examples of natural selection as it would take many generations with undetectable amounts of change. Charles lyell argued that large-scale geological change was produced by slow cumulative action. These slow processes are hard to detect over a short period of time, but they could nonetheless eventually produce major geological formations. Darwin expected that very small changes in the composition of populations would be wrought by natural selection in each generation. These changes could nevertheless produce animals and plants with very. Darwin had an enormous problem in arguing the importance of natural selection as he different morphologies and physiological functions didn"t detect natural selection.
