Document Summary

Darwin, fossils, and developmental biology: (chapter 20 page 441) Vestigial structures: useless body parts we observe today, must have functioned in ancestral organisms: georges cuvier: 17th-18th century: realized that the layers of fossils represented organisms that had lived at successive times in the past. Cuvier developed the theory of catasrophism ( explains that e/ layer of fossils marks the remains of organisms that has died in a local catastrophe such as a flood. This continues happening forming layers: jean baptist de lamarck: first comprehensive theory of biological evolution based on specific mechanisms. There are two mechanisms: principle of use and disuse body parts grow in proportion to how much they are used. - inheritance of acquired characteristics - changes that an animal will aquire during its life time are inherited by its lifetime. 20. 2 changes in earth: james hutton argued that slow continuous physical processes produced earth"s major geologic features. Gradualism(earth changes slowly) like cuvier"s catastophism: charles lyell: extended huttons idea.
