- This video will go by quickly, but try to take note of what catches your attention in this extremely fast fly-through of history of life on earth.
Now that we’ve watched the video, let’s consider these questions:
- Drawing upon on our discussion of cells and DNA as well as your own thoughts on the nature of life, why do you think it took so long for eukaryotic life to arise after prokaryotic life arose?
- Why do you think there’s an explosion of diversity and complexity toward the end of this video?
As we head into the topic of evolution, please do the following for our next class:
- To get some perspective on (cosmic) evolution through a short oral history of the universe, listen to the “What Are The Origins Of The Universe?” TED Radio Hour segment. The rest of the episode has some fantastic perspectives on biological evolution as well.
- Also, watch the PBS Space Time video below
As usual, there may be a quiz.
