According to Physorg.com, this study on epigenetic inheritance in chickens "shake[s] Darwin's foundation". Who knew inheritance in a flightless bird could induce an earthquake in northern Australia? That's not what they're referring to? They're not claiming that a neo-Lamarckian process could produce seismic activity?
For everyone running around like a chicken with its head cut off (where's my damn rim-shot?), this result is more of a shot at Mendel than Darwin. And it's not all that surprising. Don't get me wrong, it's cool to see the inheritance of acquired characteristics (unless Reed comes along and shows it to be bunk), but this doesn't refute Darwin -- whatever the fuck that means.

Myth 3: Darwin was actually a Lamarckian
This one is subtle. It implies that Darwin, because he lacked a Mendelian account of heredity, was not actually a "true" (or Neo-)Darwinian. The error depends on the extent of what is named as a school of thought in science and why.
As far as I know, the…
I'm an epidemiologist, not an immunologist or a virologist but I like reading immunology and virology. It's interesting, in some ways for me it's more interesting than reading epidemiology. In an epidemiological paper I can see pretty quickly where things are going (or going wrong) and there isn't…

Every gene involved in this 'shakeup of Darwin' evolved by ordinary means. Histone deacetylase, DNA methylase, etc etc etc.
Its not magic.
Epigenetics is an old phenomenon-- like siRNA. Even viruses code for proteins that induce epigenetic modifications.
It might be a case of direct epigenetic inheritance, but as the authors note, it might also be due to the egg environment - the avian equivalent of uterine effects in mammals.
