Schraf:First, what you completely miss is that evolution is not completely random. Natural selection, by definition, is notrandom.
ksc:Whether natural selection is or isn’t is debateable. What you have forgotten is that the mutations that you claim are naturally selected are
RANDOM
Schraf:Those organisms which have heritable characteristics which enable it to succeed in reproducing itself within particular environmental conditions will therefore spread it's genetic material more rapidly through a population that those.
ksc:Genetic differances will spread, but not differances produced by your mutations. For starters the changes would be so small that the environmental conditions would not even recognize them. In fact the time needed between a noticable morphological differance produced by mutations would be extremely long. So long that the environmental conditions would have probablty moved on long ago.
Schraf:which reproduce less-successfuly.
The environmental selection is non-random. Mutations are, however.
BTW, you are wrong anbout most mutations being detrimental. Most mutations are neutral as regards to fitness. Please provide full references to the professional literature that says otherwise.
ksc:I think you can find it in just about any book on evolution that talks honestly about the subject.
Schraf:If most mutations are detrimental, then why haven't all or most species spiraled into extinction??
ksc:Because evolution doesn’t happen
