1 EVIDENCE FOR EVOLUTION An Overview
2 13.4 The study of fossils provides strong evidence for evolution The fossil record shows that organisms have evolved in a historical sequence The oldest known fossils are prokaryote cells The oldest eukaryotic fossils are a billion years younger Multicellular fossils are even more recent Video: Grand Canyon Copyright 2009 Pearson Education, Inc.

13 13.4 The study of fossils provides strong evidence for evolution Many fossils link early extinct species with species living today A series of fossils documents the evolution of whales from a group of land mammals Copyright 2009 Pearson Education, Inc.

17 13.5 A mass of other evidence reinforces the evolutionary view of life Biogeography, the geographic distribution of species, suggested to Darwin that organisms evolve from common ancestors Darwin noted that animals on islands resemble species on nearby mainland more closely than they resemble animals on similar islands close to other continents Copyright 2009 Pearson Education, Inc.
18 13.5 A mass of other evidence reinforces the evolutionary view of life Comparative anatomy is the comparison of body structures in different species Homology is the similarity in characteristics that result from common ancestry Vertebrate forelimbs Copyright 2009 Pearson Education, Inc.

21 13.5 A mass of other evidence reinforces the evolutionary view of life Which of the following are homologous structures? A. Oak leaf and oak root B. Oak leaf and lichen C. Oak leaf and maple leaf D. There are no homologous plant structures Copyright 2009 Pearson Education, Inc.
22 13.5 A mass of other evidence reinforces the evolutionary view of life Comparative embryology is the comparison of early stages of development among different organisms Many vertebrates have common embryonic structures, revealing homologies When you were an embryo, you had a tail and pharyngeal pouches (just like an embryonic fish) Copyright 2009 Pearson Education, Inc.
23 Pharyngeal pouches Post-anal tail Chick embryo Human embryo
24 13.5 A mass of other evidence reinforces the evolutionary view of life Some homologous structures are vestigial organs For example, the pelvic and hind-leg bones of some modern whales Copyright 2009 Pearson Education, Inc.
25 Pakicetus (terrestrial) Rhodocetus (predominantly aquatic) Pelvis and hind limb Dorudon (fully aquatic) Pelvis and hind limb Balaena (recent whale ancestor)
26 13.5 A mass of other evidence reinforces the evolutionary view of life Molecular biology: Comparisons of DNA and amino acid sequences between different organisms reveal evolutionary relationships All living things share a common DNA code for the proteins found in living cells We share genes with bacteria, yeast, and fruit flies Copyright 2009 Pearson Education, Inc.
