>>2169076A clone in RL is basically a twin that's younger than you. Twins, although having the same DNA and even the get imilar epigenetic imprinting during pregnancy, are distinct people.
Plants and mikroorganisms clone themselves all the time; It's just us animals (with the exception of a few pathenogenic lizards) who have completely forsaken asexual reproduction - it's advantage of being fast and efficient is kind of negated when you hae to construct a complex body like ours either way.
