 thanks GOD

 

thanks GOD err...ME...umm...I.A.G.A.Y.

 

Anyway, the subtitle is "Experts investigate how a mysterious 'second genome' helps determine our biological fates."

 

That might generate more interest.

I hate how they overstate

I hate how they overstate the case for epigenetics in the title and subtitle. Ghosts? Second genome? Ridiculous. There's nothing ghostlike about regulatory factors, and the so-called genome is not stable enough to evolve on its own, and so does not deserve the elevation to the name 'genome'.

Epigenetic inheritance is most interesting when looking at developmental biology, from single-cell to fully grown adult. The fact that this mechanism is essentially reset when producing new offspring shows that it is not really a great mechanism for inheriting advantages from one generation to the next. Intergenerational epigenetic inheritance seems to me more like a deleterious side-effect of developmental regulation, rather than being a primary mechanism.

Yeah yeah, getting past the

Yeah yeah, getting past the public directed attention grabbing "ghost" title, I posted this hoping DG and you science folks might add some clarity to the claims suggested. I'd never heard this / these paticular idea(s) of herity cause and effect possibilities. Heck I can't, won't go reseaching everything that comes my way. So what's the truth, if known, beyond speculation? The last 20 mins is yes, no, maybe, or ???
