the story of evolution

the story of evolution is an amazing story. it is astounding that while the change that is constantly occuring is usually very slow, it sometimes is rapid and major. On Friday, I found the discussion of the atmosphere's evolution very interesting-it is amazing that there was a time when most of the organisms on earth were poisened by oxygen since our very existance depends on it. Examining the fossil record puts our position in perspective, we have no right to assume that we will be on top or even in existance forever. What is shocking to me is that the things we take for granted and view as constant are in actuality only semi-constant and that the very things we depend on are going to shift eventually. When considering the end of the human race I usually I think about it in terms of our destructive actions (to each other and the earth) and it is very eye-opening to think about the earth altering changes that have occured in the past as a result of some outside source. I think that it is important to look at evolution to put our existance into perspective and realize how fragile we are.
