… that says you have a second sort-of brain in your rear end – and that brain actually developed before the one above your neck.

Very interesting. Thanks for sharing. I love it!

A gastula brain developed before the butt. Perhaps this primitive brain servered as the only brain of our primitive ancient ancestors a couple of billion years ago. As they say, “Ontogeny recapitulates phylogeny “.

However I don’t think that group of neurons along an adult mammal guts (that control peristalsis) qualifies as a brain. Not in an adult body. It’s not even large enough to be indicated on a typical adult nervous system chart.
