No, I am not dyslexic, and this is not a typo. Natural selection is totally dependent on sex. For in order to occur, natural selection needs two advanced (positively mutated) individuals to find one another and procreate. This topic has been discussed by many critics of evolution, and no satisfactory answer has been forwarded. If by some billions to one chance there occurred some form of genetic damage that resulted in a positive mutation (the impossibility of this is discussed elsewhere), then we arrive at another massive barrier to “advancement of the species”. For in all likelihood one of two things would occur. First, the two individuals may now be incompatible for mating (due to differences in DNA) and a damaged progeny or infertile condition arises. Second, the two mate but the genetic damage is erased by the scavenger RNA that monitors and corrects damaged DNA. In this case they remain exactly as before.
During DNA synthesis, DNA polymerases fix the majority of mispaired bases in a process called proofreading. If DNA gets damaged, it can be repaired by various mechanisms, including chemical reversal, excision repair, and double-stranded break repair. So in the event of damaged DNA the cell protects itself. The most likely reason for this mechanism is the prevention of cancer, for as many have stated, the vast, overwhelming majority of mutations are negative or destructive.
Many evolutionist sites will attempt to say that evolution does not occur in spite of sexual reproduction, it occurs because of sexual reproduction. This is false. When two members of the same species reproduce sexually, the product may appear different than either parent but it is still the same species. A cross between a Labrador and a Poodle is still a dog, just like its parents. A cross between an Irishman and an African is still a human. Mixing genetic material does NOT create new species. It does NOT create new genetic material. It only mixes existing material differently. Those who call this evolution are either misled, or are intentionally misleading others.
