Eight Independent Lines of Evidence for Evolution

For Introduction to Evolution

We will be reading The Tangled Bank by Carl Zimmer this semester as we are introduced to evolution.  Chapter 1 of that book brings up the incredible case of whale evolution.  This video does too, so it’s a great complement to your upcoming reading assignment.  Moreover, this video highlights eight lines of evidence supporting the conclusion that whales evolved from land mammals.  The eight lines are:

  • Comparative anatomy
  • Embryology & development
  • Fossil record
  • DNA comparisons
  • Species distribution
  • Evolution observed
  • Predictive power of evolution
  • Nested hierarchies of traits
