Document Summary
Human genome that researches sequence at end of century doesn"t really exist as we know it. Very little, if any, stuff in the human genome that is non-functional - probably 0. Epigenetics new findings suggest number of new gene mutations in children rises dramatically with age of father at conception. Our way of reproducing 2 partners coming together to create new organism not the only way it happens on the planet. Asexual = single-celled organisms, plants, insects, fish, reptiles, etc. Asexual is easier don"t have to worry about finding a partner, waste of time, no break up of perfectly serviceable genome. In species who can reproduce either way (snails, fish, etc) start off with cloning until a parasite is introduced, once parasite in population becomes sexual reproduction. If no parasites existed in this world, cloning would take over : clones are easy pickings for parasites no genetic variability.
