Document Summary

Into the 20th century, the fossil record is bias shells of clams it is incomplete since it is missing groups. Darwin gave postulates (generally the first 2 was accepted by the population right away) Natural selection what was it selecting and what were the changes. Over the years, there have been the identification of fossils that have never been seen. Fossils of invertebrates were said to be missing (series of organisms that were locked in shale) The concept of a transition fossil (missing link) there must be intermediates. Open grasslands increasing horse transitional forms in fossils; the different forms all have the same attributes such as being fast and developing the grinding structure in the teeth. Exposure of something underneath from the archaeopteryx found that there was a mixture of reptile and bird features (birds arose from a reptile ancestor). It showed the intermediate where the bird had a tail and boney jaw/teeth.
