A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

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.

I mean, that's what dna is for. These machines aren't operating blindly (or even "cooperating" or agreeing on anything, really). They're following the code that makes up who we are.

Yeah but it's crazy how any given cell knows where in the body it is, somehow.

They don't so much know where they are as much as they're just interacting with what's there in the way they were made to, which was all put there due to the DNA to function as a whole.

And to be clear, it's all still amazing, just in a different way. Here's Kurzgesagt video that helps explain how these cells "communicate" to do things like put a body together in the right order.

Those who don't usually don't make it far.

That's not it.

Someone was probably born with toes on their head in the past and life didn't go so well that they could have children that also survived. This is why our DNA doesn't have instructions for growing toes on our head.
