Instapundit links to a publication of AAAS called EurekaAlert! which reports intergenerational research with this title.
Hardship affects the gut microbiome across generations
Here is the summary.
Hardship experienced by mothers during their own childhood or during pregnancy is reflected in the composition of their 2-year-old children’s gut microbiome.
The changes to this community of microorganisms are likely among the ways that hardship affects a child’s socioemotional development.
Apparently the sins of the fathers (or at least the mothers) truly are visited on the next generation ... gastroenterically, if by no other means.
