Re: I think we're barking up the wrong tree,
Very interesting conversation.
Back to broad or narrow gene pool & selection for specific traits, nature, at various times, does both.
Brother Adam, it could also be argued, did both. He selected bees from all over the world and brought them together. But also, he selected very specifically for certain traits and with a good deal of success.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
