I think it was the part about the critters losing their brains. That’s rather serious you know.
They’ve evolved an efficient way to continue eating and breeding by use of a certain system. This pattern of development is an advance for that species. Humans have an appendix they don’t use, is that ‘devolution’ or a vestigial remains of a time when our species DID have a use for it?
There is some doubt that our CNS including the brain parts are necessary to consciousness. It is an old question. Some creatures exhibit clear responsiveness and behavior with no hint of a nervous system at all, even our cousins the plants do that.

Not to argue with your statement, but democrats and other Liberals/socialists are living proof that brain loss is not behaviorally significant.
