It won't be for 'baser' evolutionary reasons that we've been out-competed by other species. The fact that only one thing like the human brain has ever evolved is why I'm drawing attention to it as a massive evolutionary anomaly, without precedent, that's hard to explain scientifically.


Evolution doesn't care (for want of a better word) whether we become "unfit" through competition or through self-inflicted reasons, there is no difference.
I agree that the human brain is an anomaly and without precedent, but I don't think it necessarily follows that it's scientifically difficult to explain, no more than other bits of our body. Perhaps you could specify which aspects of human brain evolution that you consider to be the most problematic and maybe we could take a look?
