Our teacher, Dr. Walker, assigned us to briefly discuss what we have learned based on specific interviews (given and read) and chapter 18 (The Cambrian Explosion and Beyond)...
As Nathan said in his response, discussing evolution without thinking of the environment...is really just a waste of time. The only way evolution exists, functions, is because of the environment. That is one thing I hadn't considered before this project, the huge changes our earth has gone through and how it has affected varying species. I actually really enjoyed reading chapter 18 on the Cambrian Explosion. As a kid, like most, this type of stuff was really the most interesting part of science. Imagining old animals, extinctions, and drifting of land masses was amazing! The section on mechanisms for extinction was particularly interesting, and really explained the material fairly and well. As we all know most people do not accept evolution. I have read differing views, and I can see some validity in all areas, empirical or not...but when looking at the facts of the environments history (which we can physical examine!) and how that affects an ever changing present number of species, it seems almost incomprehensible to deny this compelling evidence.

Outstanding answers, guys! I especially liked your analogy and I am glad that you were able to take away some valuable information from your interview and readings (including Chapter 18). The next blog assignment will be discussed in class.
