Egg alone is not a human vice versa sperm alone is not a human it takes both.
Not really.
Humans reproduce by meiosis now, but historically in the distant past is was asexual mitosis.
And asexual mitosis still can and does sometimes happen.
So it does not take both.
It usually does, because the sharing of DNA is more successful than just an exact copy.
But asexual fission is much older and more common.
