Genetic diversity: the greatest strength and weakness of the human species?

genetic diversity is good. it's like an insurance against rapid extinction of humanity and in a sense, war is good too. without war the human technology would not have developed the way it is now. it's because humans are constantly being forced to compete, weather its against wild animals, disease, or war that we are constantly forced to develop. (or else we'll be living happily in the garden of eden, naked and being vegan.) btw, genetic diversity =/= war. I'm pretty sure that Europeans fought amongst themselves as much as they fought with arabs. it's when politics and greed come to play that war develops. as for example, when the few settlers came to America, the native helped them survive a brutal cold. but when a whole colony came here trying to conquer it all, hell broke loose. of course, with recent technology even the people with genetics that are detrimental for their health is surviving and reproducing. like people with hemophilia, sickle cell anemia, diabetes and so on. so the natural selection for humankind kind of lessened. If your meaning of genetic diversity is this (the people with bad gene passing their gene to future generation) than yes. this is bad. it's like we're retro-evolving.

I wouldn't use superlatives. It isn't the greatest strength or weakness IMO. It is vital to our survival. I don't really think genetic diversity causes war. You can have war between very similar people or you can have peace with very diverse
