Darwin’s Voyage

  1. 1. Darwin’s Voyage (Set up for Cornell Notes)
  2. 2. Darwin’s Observations <ul><li>Charles Darwin was an English naturalist who developed the “Theory of Evolution by Natural Selection.” </li></ul><ul><li>Darwin went on the HMS Beagle around the world in the 1830’s and observed animals. </li></ul><ul><li>Species: group of similar organisms that can produce fertile offspring. </li></ul>
  3. 3. Similarities and Differences <ul><li>Darwin observed how many organisms are similar yet have important differences. </li></ul>
  4. 4. Adaptations <ul><li>An adaptation is a trait that helps an organism survive and reproduce. </li></ul>
  5. 5. Evolution <ul><li>Evolution is the gradual change in a species over time. </li></ul><ul><li>Scientific Theory: well tested idea that explains a wide range of observations. </li></ul><ul><li>People use selective breeding to obtain desired traits in crops and animals. </li></ul>
  6. 6. Natural Selection <ul><li>Natural selection is the process where individuals that are better adapted are more likely to survive and reproduce, than members of the same species. </li></ul><ul><li>Overproduction: making more offspring than can possibly survive. </li></ul>
  7. 7. <ul><li>Competition: competing for limited resources. </li></ul><ul><li>Variation: differences between members of the same species </li></ul><ul><li>Over a long period of time, natural selection can lead to a gradual accumulation of + traits and the disappearance of – traits. </li></ul>
  8. 9. The Role of Genes in Evolution <ul><li>Only traits controlled by genes can be affected by natural selection </li></ul>=
  9. 10. How do new Species form? <ul><li>Geographic isolation = individuals remain separated from the rest of their species long enough to develop new traits. </li></ul>
  10. 12. Continental Drift <ul><li>Continental drift is geographic isolation that occurred on a massive world-wide scale. </li></ul>
