Not specifically Paleo, but relevant to our discussions last month of
child health, is UK research reported on the BBC site on Friday:

An extract:
"Our study demonstrates how early environmental factors can alter gene
expression without mutating the gene itself.
The implications for humans are huge because methylation is a common event
in the human genome, and it is clearly a malleable effect that is subject
to subtle changes in utero."
The researchers found evidence of DNA methylation in many different types
of cell throughout the bodies of the baby mice - indicating that the
process was triggered at an early stage of gestation."
