  • 1 person is a creationist.

  • @nemirn they call that "chalk" & "board". chalkboard.

  • Thanks for posting this. 101 evolutionary biology overview. Most of the subject matter was covered in grade school, middle school, and high school. So, no one is lost when he gives this overview. 

  • Lastly, information came from a grade school web site for 8 year olds, here: historyforkids(DOT)org/science­forkids/geology/eras/cambrian.­htm

  • Part Four: About 375 million years ago, some of the fish developed legs and began to walk on land. These amphibians were the first animals with spinal cords to leave the water. Near the end of the Devonian period (360 million years ago), some larger and more complicated plants evolved on land too. The end.

  • Part Three: The first fish formed. At the end of the Silurian period, about 416 million years ago, a bunch of smaller environmental problems killed off a lot of plants and animals again and started the Devonian period.
