The reason for my interest is obvious - as of now, even without giving mutations any exact time-interval to get fixed - the theory is already in trouble for requiring more time than is available for it's purported mechanism to play out. Now if every trait took millions of years to get fixed, I guess natural selection by random mutation will have to be shown the garbage bin of history.
Some other good stuff I found in the process: Peer-Reviewed Science: There Isn’t “Plenty of Time for Evolution” How Long Does It Take to Fix a Favorable Mutation, and Why Should We Care? How long does it take for a prominent trait to evolve out of a population? How long does it take for changes made by evolution to be visible?
Salaam. Last week some unrelated reading caused me to look up "has there been enough time for evolution by natural selection" and - with lost of other stuff - I landed on a University Chicago page which was either a paper or a news item about a paper titled something like: It takes millions of years for a favorable mutation to stick. It basically said that: once a mutation which is advantageous for a species' survival occurs (remember all this is blind and unguided) it doesn't immediately perpetuate throughout the population like a wild-fire. In fact, claimed the paper, it takes millions of years for that mutation to become a fixed trait of that species. This was obviously an interesting claim so I left the tab open as I went about my other work. However, when I returned to it in the evening, and refreshed the tab (dunno why I did that, maybe accidentally), the paper was gone - the page simply flashed: "Page not Found"! Since then I have looked high and low for it but without success. If anyone can find it, please let me know. Maybe sound your friends/families studying at unis if they can point me to it. jazakAllahu khayran was' salaam
