Huh! As discussed here on SI years ago:

<This means that scientists should make room in the pantheon next to Darwin for the often ridiculed “stretch-your-neck-to-become-a-giraffe” Lamarck, who proposed that organisms change throughout their lives and pass on acquired traits to their offspring. A closer look at history shows we also need to make a little more room next to Darwin for… Darwin himself.

The modern synthesis included certain of Darwin’s theories, but discarded others, including that of “pangenesis,” his idea that each body part somehow contributes “gemmules” of information to the sex cells to pass on traits acquired through use or disuse in the parent’s life (read Darwin’s “Provisional Hypothesis of Pangenesis”).

Recent work is showing that Darwin was more correct than he’s been given credit for. In “Epigenetics in the Extreme” from the October 29 Science magazine special issue on epigenetics, Randal Halfmann and Susan Lindquist discuss protein molecules called prions, which turn out to be remarkably similar to his hypothetical gemmules.
