The even crazier thing is that DNA does not encode any of that. Behaviour and morphology is not directly encoded in there, you'll only find recipes for proteins. The zigote will divide into billions of cells that share that same recipe book. Depending on the electric and chemical signals surrounding cells are sending, individual cells get their "personalities" or function. This cell colony forms an organism which emerges from the sum of morphology and behaviour of all cells. But you'll find no recipe for an arm in DNA, it is the result of the work of the collective intelligence that is your body.

If the DNA does not encode it then it's an astounding coincidence that it happens so reliably and repeatedly.

I'm not sure in what sense there isn't a recipe for arms in our DNA. To me, it seems the DNA does encode that stuff, but in a highly compressed format that is then "unzipped" through the laws of physics and biology into a living and breathing being with arms.

I mean, the information has to be in there somewhere, right?
