Something that I've thought about for a while. When you think about our programmed symmetry and the way it is at birth or before (say just a potential) - arms, feet, eyes, kidneys..Is anyone calculating the progressive asymmetry, as the life goes? What does it depend on? And, is the symmetry so real when it's only given as a potential. I mean anything in nature will probably have a similar principle. But I was thinking about human body/function specifically and why science would actually care. Is it part of medicine/biology or math?
