Conrad Hal Waddington (08/11/1905-26/09/1975) was a system biologist who introduces the concepts of genetic assimilation and epigenetic landscape.
I personally like the idea that he worked in Edinburgh. As I have been to Edinburgh last year I'm an admirer of that place, and want to mention its role to hatch important philosophers, of which David Hume is my favored. The phenomenon that at some places gather forward thinking people while expelled from other is consistent with the fauceir concept of fauceir inheritance of a beneficial social framework.
