AFAIK it all boils down to the fact that during embryonal development our cells, which at that point were just a blob of undifferentiated autonomous chemical machines, somehow managed to unanimously agree upon the cardinal directions (up-down, left-right, front-back) for future development - and thanks to this, we don’t have toes growing out of our ears.
In science that is called symmetry breaking (going from a homogeneous blob to left right something) and a very active topic of Research.
Gravity is what makes this happen. Guess what probably is a concern in space?
You know that we’ve gestated various animals in weightless conditions on the ISS, yes? They look normal.
You JUST realized that. 🙄
It’s not that incredible, considering we can get cysts full of teeth and hair inside the body
Wonder if we could use that phenomena to regenerate teeth in a lab for replacements and dentures.
Imagine if you suddenly sprouted a tumor with functional tastebuds in your colon
The toes are the powerhouse of the foot
