I mean apart from a few crabs with large single claws and fish with both eyes on the same side of their body, why is practically the whole animal kingdom symetrical? What is the useful function?

It's not to do so much with the useful function; rather how the symetry arises. Each organisn arises from a single cell. The clump of cells becomes a ball, that then flatens out and develops a neural tube (becoming the spine and brain complex). From that, everything fans out. as the neural tube forms by a symetrical folding, so all things from it are symetrical as a mirror image forms or each part.

Great question.
Perhaps based on Caos theory, everything respect somekind of symetric shapes but they can appear assymetric. Paterns are created base on it.
Perhaps we have locomotion issues if we take an body assymetric and they were cutted during evolution process. We have radial symetric format what put down our cells division in pairs (Or radial is just an coincidence about the shape and our cells division in paris would determine pour final symetry.
Patern recognize standard can happen too with assymetric standards.
About internal organs, we can just adjust it based on evolution and when we start to "acquire" our internal organs, but our appearence is based in mirroring.
No answer and thanks by it. Something that I need look for.
I believe this answer is in mathematics.

1) Symetry is more simple to produce from a developmental standpoint. Assymetry requires more genetic information and more things could potentially go wrong.
2) Symetry makes locomotion much easier. Asymetry requires more complex motion patterns and therefore more complex nervous systems.
Unless the asymetry produces a reproductive advantage it just simpler for an organism to develop symetrically.

It just happens to come out that way. The embryos start out as a single cell and then divide many times, which is a geometric pattern, so it is easier and much more likely that the animals will be symmetrical, except, of course, for necessary exceptions.

balance, for one.
Animals are externally symmetrical, but the arrangement of their internal organs is not. One lung is larger than the other to make room for the heart, which is off to the left. The stomach and liver are off the sides. We favor either right or left. Brain function is different in the two halves, et cetera.

balance, beauty, and think about it, most humans aren't, so someone has to be
