Rather hypocritical of you, seeing how you are spreading the gospel of darwinism you were indoctrinated into absent any understanding, and sprinkled with racism.
I hate to spring to the defence of an AC against another AC, but you seem to be unaware that darwinism also implies an end to racism and even speciesism, because there are no dividing lines.
You need binary thinking to get hate crime, and modern biology is delightfully free of that..
His comment had nothing to do with souls or religion, his point was nobody gets to chose, and you wouldn't be barking that cr@p had you been born in the "wrong place", cuz you'd be jerky drying under the sun regardless of how "fit" you consider yourself to be.
"Being born in the wrong place" is a double absurdity - both because you can no more be the offspring of someone else than you could be the offspring of a wrench and a comet, and also because the human being isn't a binary on/off, but develops gradually with its body - the being is a product of both genetics and environment and becomes progressively more a self over the formative years, until perhaps losing the self again at the end. There is no magical soul involved, with a potential for being transplanted.
Killing poverty is exactly as reprehensible as handing out condoms in this regard. You prevent a lot of potential people from ever becoming aware entities, and open room for others who have a chance of leading better lives. It requires some seriously magical thinking to think one of these as bad and the other good.
As for "fittest", the offspring of people living in Kalahari are, up to modern times, those most fit (or, rather, least unfit) for surviving and reproducing in Kalahari. And the offspring of Inuit seal hunters are, up to modern times, those most fit for surviving and reproducing in that environment. Neither would face good chances of nurturing viable offspring if transplanted to the other environment.
