>>11234469>What is the evolutionary purpose??Instead of asking what the evolutionary purpose of a maladaptive behavior like that is, you should ask whether the benefit of having a neuromuscular system incapable of producing occasionally bad results would outweigh the massive cost that level of ironclad perfection would require.
If you needed a car to get to your new job starting next week and could either get a shitty car for $10,000 or a perfect car for $1,000,000,000,000 you would necessarily pick the shitty car because you don't have the GDP of a large developed nation to spend on transportation to work.
Evolution is only going to work with what can actually emerge every step of the way. Perfection is not a reasonable expectation for a naturally emergent structure or process. Evolution isn't a conscious entity wanting to do a good job. It's the result of whatever works well enough to last long enough to reproduce.
