So I just watched a Nova documentary on epigenetics called "Ghost in your Genes"... I had never heard of epigenetics. Apparently its things being passed down amongst people by means other than our GENES and DNA. Things like smoking being passed down from grandparents to grandchildren and resurfacing as asthma or... if a grandparent goes through a period of starvation he could have grandchildren with diabetes. All kinds of strange things passed down in unexpected ways.
It reminded me of crows and how they can pass down FEAR of certain things genetically. Perhaps its actually passed down epigenetically. Has anyone seen a Murder of Crows? A Crow is taught to fear a man wearing a certain mask. Later that crow has offspring and the offspring CLEARLY act as if they remember this man in the mask... and to fear him.
Anyway, watching it also had me thinking about the role epigenetics must play in evolution. I mean only so much of our DNA can explain us. I've heard plants have more complex genetic data than a HUMAN. Humans and monkeys share a near 99% of their respective genomes. It actually makes me think... evolution has always made sense but has always seemed like maybe there's something missing. Evolution seems to move almost too fast to me for some reason. To me, anyway, there IS room in the theory for some directive mutations and mutations caused by the environment... perhaps this epigenetics could explain some of that. I guess that is Lamarcks theory of evolution. I never quite got over his theory. I have always thought there is some sort of truth to it. Maybe epigenetics is it...
