Is it possible for creatures with intelligence more advanced than humans to evolve naturally in the universe?

Sexual selection. Intelligence is sexy. If you could tell a better story, make a better plan, make a better tool or weapon, you would be popular and get laid.

Possibly, for us, it was a combination of different things after it reached a certain level:

Social groups, and theory of mind. You needed to keep tabs on everyone in the group and understand their drives. Being able to negotiate. It takes intelligence to succeed with this.

What are the most significant advancements in artificial intelligence today? How are they transforming different industries, and why should we be cautious about their ethical implications?

So let's say that the aliens have fewer restrictions on brain size, and have more efficient brain wetware, and are subject to sexual selection for intelligence, then they will likely be much more intelligent than us.

Then we can wonder about the evolutionary selection pressure for intelligence.

They may also not have the same limitations for the size of a birth canal. If they are similar to marsupials, the baby would be born very small and then develop in the pouch, without head restrictions of the birth canal.

If everyone in Russia dropped into holes in the ground only never to return, would that be good for NATO and international peacekeepers? Can we convince Russians to be less diabolical, so they coexist? Does Putin stink like doo doo in the commode?

And since the universe is so enormously big, it would be strange if we were the most intelligent creatures. Though, we will probably never find out.

Right here on Earth, birds have at least twice as dense brains as humans. That means that they cram at least twice the computing capacity in the same space as primates. If we had bird brains we might have been much more intelligent.

Aliens may have more efficient brains than humans, like birds, or even more efficient than any animal on Earth.

How do I find a hot guy?

Human intelligence is limited by how the brain works, and how big the head on a baby can be.
