  1. One particularly interesting question regarding this issue would by: why does Autism Spectrum Disorder (ASD) still exist? One in 68 children is diagnosed with ASD in the US. This should not be described as "rare". Theoretically, since individuals with ASD have social difficulties (which is what "autism" means; auto=self, -ism= condition or state,) they should have gone extinct. One explanation would be that the mutation that causes the condition is a point mutation, that is, a mutation of a single gene, but this is not applicable to ASD. Actually, ASD, as is the case with many other condi
  2. That’s correct. The example of the individual I explained above was only for clarification.
  3. Not directly, but, indirectly, survival must be related to reproduction. If an individual has traits that contribute to his/her survival but is unable to reproduce, he/she won’t be able to pass on their traits. An individual could be born with an inborn disease that only gives him 2 years to live. This can happen because the incidence of mutations is not 0%. His trait won’t be as frequent as another fertile individual living for 80 years. Natural selection chooses the most effective traits (compared to other traits that existed) to be the most frequent in a group. Diabetes and
  4. I agree. But this was not the idea I was trying to present. The point is that when such traits exist, they could be related to reproduction somehow. I read in a book, and checked women’s responses on Quora about whether they found muscular men more attractive, and found that most of them do. Yes, not 100% of them, but most of them did. I tried to relate that to fertility. I think that most men, too, care about curvature and and other secondary sexual characteristics that are suggestive of female fertility. An interesting thing here is that some traits may become less common in the futu
  5. Natural selection determines what genes are going to be more frequent. Preferred genes are the ones that help in reproduction because, simply, if a human being can not reproduce, he/she is not going to be able to pass their genes on to next generations. Therefore, the ultimate result of natural selection is genes (or combination of genes) that are the most suitable or potent for reproduction. This explains why most people that exist today are able to reproduce; they are prepared physically (have functioning sexual organs). Similarly, we are prepared psychologically. After all these
