D.N.A. from Males May Stay With Mother and Womb-Sister's Brains for Decades

A recent report found that D.N.A. from male feotuses may remain in a mother's brain for decades in a phenomenal micro-chimeraism. One research study found that women with male children had a lower incidence of Alzheimer's disease by more than one-third. The role that the feotal D.N.A. may play isn't known and neither is the way it might interact with the D.N.A. of the host.

Sisters that shared a womb with a brother also receive male D.N.A. enhancement. One might wonder what effect multiple marriages and children from different fathers might have upon a mother with D.N.A. contributions from several men in her brain. Their might have been a physical reason why Christian marriage traditions are less confusing for society coinciding with the spiritual.

The natural temporal recombinant D.N.A. presents several new avenues for research both good and bad as is usual with things biological. One might wonder if contract of D.N.A. & R.N.A. viruses in Africa and elsewhere in tourists (as was the case with a 2008 incidence of Marburg virus when two Dutch tourists visited a Ugandan bat cave and one became infected) allows viruses to evolve with recombinations derived from interaction with their host's  genetic endowments.

The post-birth phenomenon of D.N.A. changes in human brains through sexual reproduction presents the interesting prospect that heterosexual marriage is a way the human species was brought into a closer social balance.
