Document Summary
A change in the frequency of the alleles of a population. Mutation which creates a new allele that is favored. Descent with modification: a darwinian view of life. The first convincing case of evolution was published by charles darwin in 1859. The most popular hypothesis for the origin of species was creationism. May be strictly biblical or may involve continual creation. The evidence of some of the organisms which have existed on earth is preserved as fossils. For bacteria => a day or two could be plenty. The differences between fossils and living species are great. A succession of organisms is seen in the fossil record. However, these results were not used to support evolution. A french anatomist (cuvier) founded the science of paleontology, the study of fossils in the late 1700"s and early 1800"s. Cuvier explained the layers of different species were caused by separate catastrophic events.
