There may be a tiny shade of overlap between the processs of "old vs new" epigenesis, but the new approach (to quote Chris) that relies on genes and their hereditibilty and (my addition) whether the behavior is selected/expressed/ displayed covers a wide(r) range of behaviors than relatively simple head-bobbing. Or so it seems to me. D

DKH I think the term "epigenesis" has changed its meaning since then. The "epigenesis" of the first half of the 20th century (as used by, say Piaget) was derived from the "old" meaning of "genetic" which simply had to do with the "origins" and development of things -- when "genetic psychology" was simply (what we now call) developmental psychology The new epigenesis derives from the new meaning of genetics -- pertaining to heritable biological "genes" composed of DNA.
