can you just stop just for a moment????, and quit being 'so ex-JW,' analyzing this and analyzing that,,please try to just embrace the beauty, the awesome, the peaceful moment!!!
nooooooooo, here we go analyzing 'genes,' 'recessive.' 'artificial' that, 'evolution' that, 'incest' this, 'geographic isolation' that.
I guess when we were kids we didn't get to ask 'why' anything, so now we make up for it! 'Why?' everything. (see, I have the 'over-analyzing curse' too)
