Document Summary

One of the things that has unified all of biology and said by many scientists is the insight that there is a commonality to life. When you look at the diversity of life you see incredible variation as evident in the picture below of arachnoids and crustaceans, but at the same time there is interrelationships/there are commonalities as well. The theory of evolution gave us the basis that life has a common origin and you get diversification from that point. * (cid:862)all thi(cid:374)gs (cid:271)ei(cid:374)g e(cid:395)ual, s(cid:373)alle(cid:396) a(cid:374)i(cid:373)als ha(cid:448)e p(cid:396)opo(cid:396)tio(cid:374)all(cid:455) la(cid:396)ge(cid:396) (cid:271)(cid:396)ai(cid:374)(cid:863) geo(cid:396)ges cu(cid:448)ie(cid:396).
