Peter Medawar Quotes
I shall borrow two words used for a slightly different purpose by the great demographer Alfred Lotka to distinguish between the two systems of heredity enjoyed by man: endosomatic or internal heredity for the ordinary or genetical heredity we have in common with animals; and exosomatic or external heredity for the non-genetic heredity that is peculiarly our own - the heredity that is mediated through tradition, by which I mean the transfer of information through non-genetic channels from one generation to the next.

Sir Peter Brian Medawar OM CBE FRS was a British biologist and writer, whose works on graft rejection and the discovery of acquired immune tolerance were fundamental to the medical practice of tissue and organ transplants. For his scientific works he is regarded as the "father of transplantation". He is remembered for his wit both in person and in popular writings. Famous zoologists such as Richard Dawkins referred to him as "the wittiest of all scientific writers", and Stephen Jay Gould as "the cleverest man I have ever known".
