“This new example of the success of asexual reproduction adds to the existing problem that evolutionists have (and many acknowledge) of explaining how and why sexual reproduction arose. If it is supposed to have been because of the alleged advantage of sex, this crayfish shows that an organism can be spectacularly successful just by cloning itself. So why should evolution ‘bother’ to evolve sexual reproduction in the first place?”
Conclusion: This is NOT evidence for Evolution and in fact, further problematic to the evolution of different sexes.
