Didn't Mendel send Darwin a copy of his work on pea plant trait transmissions between generations? Ed Larson talks about this in his audio version of _The Theory of Evolution: a History of Controversy_. I've heard this before. So if Darwin had received a copy of Mendel's work, yet had taken the time to actually read and grasp the significance of Mendel's work, one could only wonder what changes Darwin would have made to his ideas about inheritance.
Yet, wasn't Mendel aware of Darwin's work?
Mendel was well ahead of Darwin (and Ted) when it
comes to understanding the transmission of traits
(ontogenetically significant factors). The only reservations I have are for the overly simpistic one gene : one trait views. Development is often far more complicated than simplistic 1:1 mapping implies, but nonetheless doesn't need paranormal phenomena to explain it.
Organic memory is dead on the vine, but has historic
significance for memetics because of the
