DNA May Carry a Memory of Your Living Conditions From Childhood
An anonymous reader writes "Canadian and British scientists have found that how rich your family was when you were a kid — as judged by wealth, housing conditions and occupation of parents — has a huge impact on your current DNA. 'This is the first time we've been able to make the link between the economics of early life and the biochemistry of DNA,' says Moshe Szyf, professor of pharmacology at McGill University. The study did not show whether the DNA changes identified are passed on to offspring, but if so, repeat cycles of poverty could be putting poor children at a serious disadvantage for heart disease, diabetes and lung disorders."

What is this based on? Perhaps extra robustness is built in for exactly the reason that you may run more risk? So having poor parents may actually give you an advantage...
Sounds a lot like a Nova program I saw some time ago. It titled 'Ghost in your genes'. It talked about how epigenetics control how your genes are expressed and they had noticed some inherited traits based on whether the ancestors were poor, starving, folk or not.
