Nikki clarified: "The lethal gene theory says something like this: if
there is a
failure in the reproductive cycle of more than 3% of a species, that
species
doesn't survive. Can't remember the author."

So does this then apply to breastfeeding?  Also, how does the increase
in infertile couples having babies via technologic interventions
affect breastfeeding failure/ success rates?
