Well I believe it does have something to do with evolution, my good man, we have prospered because evolutionary pressures endowed us with a superior intellect. We use it, we dominate. 99.9 % of all species which have ever existed are extinct (I have not yet read your link, I may find time in the by-and-by). We were not around for those events, so apparently, this IS the way nature works. Your anthropocentric bias is showing. In closing, I am somewhat familiar with the concept of evolution, however, always anxious to learn if you would be so kind...
