Now this is interesting, thanks!<quoted text>
Lamarck was definitely wrong about how evolution works. And that is why we don't teach "Lamarckian Evolution".
However, the concept of epigenetics does seem to indicate that something remotely similar to what Lamarck thought might actually be true. It doesn't vindicate his idea since he was just making a sort of "common sense" observation. But it is interesting.
"In biology, and specifically genetics, epigenetics is the study of changes in gene expression or cellular phenotype, caused by mechanisms other than changes in the underlying DNA sequence – hence the name epi-(Greek: επί - over, above, outer)-genetics, some of which are heritable."
Now I have to think of a way to casually slip "transgenerational epigenetic inheritance phenomena" into a conversation.
