Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Spiders (I'm not sure this is all of them) have to liquify their food because emergence placed their brain around their throat. As the brain grew it restricted eating in a rather nasty feedback situation.

A literal bottleneck in one way, but also one that prevents further emergence.

But I agree that our human bottleneck is cultural. Our bodies haven't had much time to further emerge, in only 3000 iterations.

You can't be me, I'm taken
