I encourage you to reply, but not more than once a day, with a interesting new fact. Let’s stretch this out instead of dumping all the interesting facts out all at once. (Btw feel free to comment on the interesting facts as much and as often as you want)
edit: posting a source for your fact is strongly encouraged.
Your first anatomical feature was your anus. Humans and all vertebrates (and starfish etc.) are 'deuterostomes', in early embryonic development the hollow ball of cells starts to fold inwards and the hole produced eventually becomes the anus. In 'proterostomes', such as insects and molluscs, the same initial hole becomes the mouth.
The human body and life is so fascinating! I was studying it for a time but couldn't pursue because of anxiety and asd.
Amazing! I would love to work in biology.
I rode that particular train as far as it would go, 34 years as a research biologist.
