also if future people exist, why don't we seem them today? it's sort of like evolution and how it doesn't exist - why are there apes today if they EVOLVED! check and mate mister science.
Why are there only 2 sexes??!
evolution take years and each being evolves differently.. we adapted into humans others could not... they adapted differently and not in the best way.. all possibilities were covered but those who were fit enough could survive.. rest died
only 2 sexes... sexes are a way to increase the rate of evolution.. an asexual being will reproduce with minimal changes to the DNA because it only has its own experience to rely upon and hence the evolution is slow and not well rounded.. a sexual reproduction ensures mixing of two very different sets of chromosomes and hence it speeds up the evolution in a ridiculous manner.. Nature favors this path even if it risks extinction more than it does with being asexual or self reproducing..
only 2 sexes because sex is a way to bring two able beings to come together and reproduce.. hence only 2 are required rest will be redundant. Nature needed an excuse to bring two beings together and sire an offspring with best of both.. although not always best of both happens but nature runs its course and the unfit die ensuring the next generation to be more evolved than the previous.
in primitive times or in primitive animals the weaker offspring are likely to die ensuring natural selection.
sexual reproduction means that the new being created has the best of TWO beings who themselves had the best of TWO others each... create a binary tree and see..
