The following are several quotations from it:
“Methylation, which is the predominant epigenomic marker within our genomes, is like a fingerprint on our DNA that can be modified by both genetic ancestry and by the environment,”
“It’s an elegant work that addresses what I think is an important biomedical research question [on] the complex interplay between genetics and environmental exposures on individuals,”
Most researchers agree that individual epigenomes are partly inherited from our parents but can also change as a product of our environment. Starting with this premise, “we asked a simple question,” said Burchard. “What proportion of the variation in the epigenome, meaning the methylation pattern, can be explained by genetic ancestry or self-identified race/ethnicity?”
This is of special interest to me, since I am hung up on the idea that theistic evolution must incorporate some element of purpose, and not be as (apparently) random as Dawkins would have us believe. DNA methyltransferase may be the way God allows a bit of Lamarkian evolution (experience of a parent to be passed on to the genome of progeny) and thus add a little more meaning to human existence.
