What makes you think all creatures visible to the naked eye have a brain?
There are plenty that don't. Some of them are quite large.

Didn't really think about it too hard, except to disqualify single celled orgamisms.
Given that I'm going to define any assemblage of neurons as a brain, what creatures are you thinking of?

Oh, he has a brain.
He got it from the heads of three snakes and a newt, combined using dark alchemy.

I was thinking about lancelets,
but the way you are defining a brain shoots down that argument.

Carry on, nothing to see here.

Ooohhh hang on a moment.
What are those things that are lumped in with the chordata because the larval stage are similar to tadpoles. I think they're sea squits. Do they have a brain in the adult form?

Possibly, possibly not.
I think you're missing my point though, which is that out of all the brains on the planet, the human one is pretty unique.

I probably am.
To be honest I didn't read the whole post. I just got to the bit about all creatures visible to the human eye having brains, and saw an opportunity to be a pedant.

That's how my brain works don't you know.
