colors-2-_custom-afc93498ec5df91f516ee25aa3141c750524cd16-s700-c85For class on Dec. , please do the following:

  • Read Biology 20.1, 20.3, 20.4 (20.2 optional) or EO Wilson’s Life on Earth chapter 3
  • Listen to this news story about color and be prepared to answer these questions in class: (a) what selective pressure(s) are mentioned in the news story? (b) what is the result of the pressures?
  • Also, 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.
