I just realized how incredible it is that we don't have toes growing out of our ears.

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. A showerthought should offer a unique perspective on an ordinary part of life.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics
- NEW RULE as of 5 Nov 2024, trying it out
- Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct-----

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.
Those who don't usually don't make it far.
Survivorship bias
That's not it.
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.

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.
Sure, but every cell has the same DNA. Yet some "decide" to "agree" on making toenails, while others differentiate into eyes.
If an embryo decides to split in two, and then sends out the marker that "this is the right side" and it's too close to the other embro, there will be a set of identical twins, but one will have the heart on the right side, appendix on the opposite side etc. This needs to be known if the "mirrored" person has a colonoscopy, since the colon is folded the opposite direction.
