This brings to mind an interesting article I came across that
referred to, in addition to the "normal" modes of evolution that we
can see and measure, parental evolution. The concept being that
certain traits are more desirable to a parent, and therefore that
offspring would receive more care from the parent, increasing the
likelihood that it would thrive. The example it discussed (according
to my hazy memory) was of primitive humans and child rearing, and how
a child that was quieter or looked a certain way was in some way more
attractive to the parent or community, so that child would be more
likely to picked up in the event of danger, or fed when food was short.
By this theory, wouldn't the Chinese have stopped producing female
babies? (Yes, I know it doesn't really follow, but it was the first
thing that popped into my head when I started thinking, "what are some
traits that could be so adverse to a parent (especially one with
post-postpartum hormones flowing) to cause the parent to be less caring
then they are naturally apt to be", and this one popped into my head.)
