Most people understand that sexual lust has to do with propagating genes. Copulation in nature tends to lead to reproduction and so to more genetic copies. But in modern society, most copulations involve contraception, designed precisely to avoid reproduction. Altruism probably has origins like those of lust.
Richard DawkinsI think nobody would claim that random genetic drift is capable of producing adaptation, that is to say the illusion of design. Random genetic drift can't produce wings that are good at flying, or eyes that are good at seeing, or legs that are good at running. But random genetic drift probably is very important in driving evolution at the molecular genetic level.
Richard DawkinsIndividuals are not stable things, they are fleeting. Chromosomes too are shuffled into oblivion, like hands of cards soon after they are dealt. But the cards themselves survive the shuffling. The cards are the genes. The genes are not destroyed by crossing-over, they merely change partners and march on. Of course they march on. That is their business. They are the replicators and we are their survival machines. When we have served our purpose we are cast aside. But genes are denizens of geological time: genes are forever.
Richard DawkinsOrganizing atheists is a bit like herding cats; They are on the whole too intelligent and independent minded to lend themselves to being herded.
