That’s what we’ve been talking about the last few days. We’ve talked about theories and evidence that supports or refutes those theories. There have been lots of theories of evolution but we’ve focused on two…

1. Jean-Baptiste Lamarck

   • Acquired Characteristics
   • Whatever traits or habits that you picked up over your life, you passed on to your children.
   • Believed that if you really “needed” something or some habit to survive you could acquire it.

1. Charles Darwin

   • Descent with Modification – Present living beings are modified decendents of older organisms and species.
   • Modification by Natural Selection – Environment limits the growth of populations. Some Organisms have traits that make them better able to survive in their environment

Evidence suggests that Drawin’s theory, which he illustrated in his book “On the Origin of Species”, is accurate. Can you think of any instances of organisms that look like other species but have some type of special advantages to help them survive in their environment?
