…If I have this correctly, from an evolutionary standpoint, the mouth formed first but it was also the waste hole 🤮, because there was no anus. And then came anuses, and with it bilateral body forms (the blueprint for both chickens and us), and then eggs, and then Galliformes – proto-chickens: https://en.wikipedia.org/wiki/Galliformes – and then us, and then Colonel Sanders 😱 https://mastodon.social/@urlyman/111074681213203181
