I’ve been thinking, lately, how natural selection manifests itself in myriad ways among plants and animals: adaptation to changing environmental conditions ensures survival of species. And, individuals with superior survival skills pass on their genes to ensure superior off-spring better capable of surviving and thriving in harsh natural environments.
It seems in some ways unfortunate similar evolutionary progress doesn’t happen among humans where mating practices appear to be pretty thoughtless with regard to what sort of off-spring might be produced, you know, in terms of the capabilities needed to deal with life. The less-able results of indiscriminate coupling are, of course, cared for by the more able and humane where as in the animal kingdom such unfortunate progeny would certainly parish.
Still, it seems to me compassion should rule the day. I do think virtuous behavior toward the less fortunate should be expected of thinking beings, but, being thinking beings, mankind might do well to think before passing on seed.
