So the question was: Why has sexual reproduction proved so successful?
Muller's theory, proposed more than 50 years ago, attempted to describe a hidden cost to asexual reproduction that would allow sexual reproduction to come out e ...[text shortened]... nts is a fast moving field. I have not been up to date for the last 15 years, at least
Oh yes, I guessed that Muller's theory was invented for explaining why sexual reproduction has proved more successful over asexual reproduction despite its cost.
But, surely we should all know better now because we should know this theory to be clearly false! We now know that the correct explanation is, instead, that sexual reproduction gives better and faster ability to genetic adapt to a changing environment and this ability often more than compensates for the high cost of sexual reproduction.
This is why I cannot understand why it was even mentioned in the first link I gave! Didn't those evolutionary biologists that did that recent research keep up to date on these basic facts? Or did they simply fail to understand how natural selection actually works and thus how natural selection would inevitably stop any 'Muller's ratchet effect'!? -I can only wonder.
In fact, I am surprised that the wiki page on this failed to mention that the Muller's theory it widely regarded as wrong and then explain why!
The wiki page does mention Back Mutation.
Yes, I noticed that. I also noticed how it strangely just left it at that and just immediately moved on instead of taking that to the natural next step by stating the obvious fact that the existence of back mutations is one of the reasons why the theory may be wrong! In fact, it gave no explanation of why the theory is or at least could be wrong nor even mentioned any common criticism of it. I was not too impressed by that!
