Document Summary
Think of ourselves and other species, bacteria, viruses as survival machines ! All survival machines for the same kind of replicator dna! Our ancestors may have not been organic molecules, rather inorganic crystal minerals ! Dna does two things - replicate and supervise manufacture of proteins! Genes are at least partly responsible for their own survival in the future,their survival depends on the ef ciency of the bodies in which they live and build. Natural selections favours replicators that are good at building survival machines, genes that are skilled in the art of controlling embryonic development. The manufacture of a body is a cooperative venture of such intricacy that it is almost to disentangle the contribution of one gene from that of another. A given gene will have many different effects on quite different parts of the body. Any one individual is just a temporary vehicle for a short lived combination of genes.
