  3. 3. <ul><li>Evidence for evolution: </li></ul><ul><ul><li>FOSSIL RECORD </li></ul></ul><ul><ul><li>HOMOLOGOUS STRUCTURES </li></ul></ul><ul><ul><li>SIMILAR EMBRYOS </li></ul></ul><ul><ul><li>SAME DNA/PROTEINS </li></ul></ul>
  4. 4. <ul><li>If the bone structure in an animal becomes more advanced throughout the years it supports evolution because of the gradual change taking place. </li></ul>
  5. 5. <ul><li>___________________________- </li></ul><ul><li>similar structures which indicate common ancestry </li></ul>HOMOLOGOUS STRUCTURES
  6. 6. <ul><li>Vertebrates are believed to have had common ancestry because there are marked similarities between the embryos of each class. </li></ul>
  7. 7. <ul><li>The same blood protein in a group of species provides evidence that the species descended from a common ancestor . </li></ul>Universal genetic code: SAME nitrogen bases code for SAME codons code for SAME amino acids code for SAME proteins

Beagle </li></ul><ul><ul><li>Explosed him to a variety of different ecosystems </li></ul></ul><ul><ul><li>His observations of these different ecosystems and the organisms that made up those systems led him to the conclusions found in this book. </li></ul></ul>
