Science daily has an article on Is There Really A 'Mommy' Gene In Women?
“Only in recent times have women acquired significant control over their own fertility, and many are preferring not to be saddled with the burden of raising children.
"The question is whether this is just a result of economic factors and socio-cultural conditioning, as most analysts claim, or whether the choices that women are making about parenthood are influenced by genetic inheritance from maternal ancestors that were dominated by paternal ancestors.”
Take a Look.
The article ends with “The bottom line from a biology viewpoint is: in order to have your genes live on, you’ve got to have kids. If you don’t, then they’re going to disappear,”
