Document Summary
Lyell uniformitarianism observable processes occurring at a constant rate have always been in progress (explains formation of geologic features over great time periods) Founder for the idea of natural selection: wallace had the same idea at the same time but let darwin take most of the credit. Observation populations have a great capacity to grow, but are ultimately limited by resource availability. Inference competition between individuals in a population for resources. Observation individuals vary within populations in heritable traits related to competitive success (ultimately survival) Inference some individuals more likely to survive and reproduce than others. Observation individual may also vary within populations in heritable traits related to reproductive competitive success. Inference some individuals more likely to reproduce than others. When you put the observations together, you get the idea of adaptive evolution or descent with modification: a population"s characteristics change over time, as advantageous traits become more common.
