We know from our clinical experience in the practice of medicine that in diagnosis, prognosis, and treatment, the individual and his background of heredity are just as important, if not more so, as the disease itself.
Heredity provides for the modification of its own machinery.
Life consists not simply in what heredity and environment do to us but in what we make out of what they do to us.
We live in a dancing matrix of viruses; they dart, rather like bees, from organism to organism, from plant to insect to mammal to me and back again, and into the sea, tugging along pieces of this genome, strings of genes from that, transplanting grafts of DNA, passing around heredity as though at a great party.
For me, ancestry is just one thing that connects us to people, and feeling connected to other people is generally a good thing, as long as one kind of connection does not have primacy over all the others. Heredity, race and nationhood are not the best criteria by which to judge our fellow humans.

Here he tells us that the new birth is first of all 'not of blood'. You don't get it through the blood stream, through heredity. Your parents can give you much, but they cannot give you this.
Both of these branches of evolutionary science, are, in my opinion, in the closest causal connection; this arises from the reciprocal action of the laws of heredity and adaptation.
