Document Summary

Evolution is always slow- evolution can be very fast based on selection or envt better, we are in a diff envt now. Topic: how and how fast natural selection works in sexual animals. Much info about how evolution by natural selection works and much of it is incorrect. Genetic design info - creating animals as individual vehicles- getting into habit of looking at natural selection from viewpoint of the gene. The gene is the unit of interest- not the group, not the species- unit of interest. Present vehicles are an (cid:498)improvement(cid:499) from past time in history newer versions are somehow better, we are more evolved not necessarily true. Ancestors were good competitively between other copies of information not that we are. Take into consideration the envt that our ancestors were in doesn"t mean they were. Another misconception is that we have (cid:498)bypassed(cid:499) natural selection- we exist because of.
