hmmm i belive that humans dont really evolve anymore, the process would take too long
FYI, how we develop our eyes take millions of years from the beginning where we just have photo sensitive patch on our body and SLOWLY evolving into retinas , pupils, etc.
even if we DO evolve, its due to DNA manupilation artifically.
As of the evolving part, we humans are actually de-evolving due to the fact where we are getting more and more civilised.
There is a theory that says that we use almost all of our brains in the past, but as time goes by this certain part of the brain or dna or whatever is deemed unnecessary for our survival as thru out the years it has been "hibernated" in our brains, aka Junk DNA.
Maybe there will be a time were there is a super virus that trigger a response to the junk dna and we may in turn "evolve" for our sake of survival?
