Why have the evolution compromised with the brain?

[Gliese123]

As the thread: Why haven't the brain among different species developed in general to a size comparable to Homo Sapiens. And even though the brain among Neanderthal was considered to be bigger than Homo Sapiens, did the evolution considered that it was too "big" or too "clumsy" and the race died? Even though environmental factors and limits are definitive for the time span among species development, I think a bigger, more developed and advanced brain is both increasing social & survival aspects for a species, even though what species I'm referring to. Sure, there are limits for how big a brain can be since human anatomy demand a constant temperature , but wouldn't that "easy part" be adapted by the ambient environment? The nature has facilitated many obstacle for lifeforms around the world, why not the limitations for extended brain size? Or haven't the evolution "caught up" the time span?

The brains for different species seem to function just fine, why would they need to change? What makes you think that human brains are maxed out and that they need to be bigger/more advanced?

Why not?

You've posted idle speculation, you have provided zero scientific facts to back up anything you've said.

You don't want people to question you or point out that your thoughts lack a scientific basis?

Then there is nothing to discuss.

Obviously you did not post with a desire to learn. Do some research on brains, there is a lot you can learn if you truly have a desire. After you have some facts, then you can repost specifc questions about those facts.
