So I built a stegosaurus model kit, which included some factoids in the instructions. One of these factoids was that stegosaurs are not believed to have had a secondary brain in the hips to help them control their rear half after all. That was wild to me, since the whole stegosaurs and sauropods with their tiny heads needing a secondary brain for their huge bodies was commonly accepted back when I was a kid. So I looked it up, and indeed, the current hypothesis is that the cavity that the second brain was thought to occupy is used for a thing called a glycogen body. But what exactly does a glycogen body do? We’ll get back to you on that, apparently.
It was a thing when I was a kid. The older you get the more of your basic education gets proved wrong.
Public school is great
When I was a kid they told me that different parts of the tongue have different taste buds
A surprising amount of teachers work like LLMs. No idea what they are talking about but extremely scared of admitting it.
