How did evolution make a torus?

 Why are embryonic cells in division act like 4D elements?

The cells in embryo tend to spiral u in movement making a torus center. Evolution went from a 3D system to 4D between the jellyfish and us. If evolution were trying to get as many relative primes from the genes as possible, then at 4D, evolution must have master spiral, chirility in gene as an information source. If nature had a pond where chirality was segmented, perhaps by the actions of jellyfish, then the various combinations of genes would eventually utilize the redundancy, using evolutionary selection for 3D genetic codes.

The jelly fish gene remains, call it spin, it appears as the placenta, and has the leas entropy and eventually discarded. But how do the cells select their genetic expression? The kinetic energy tells the cell when, the mothers chemical input tells the cells what. The mothers input always recreates the original pond.  The chirality appears twice. Kinetically the anus and mouth separate, but they must have an absolute north south pole in gene chemistry, meaning the mothers influence guaranteed to trigger the complentary gene expression.

This 4D world would have originated in a very energy and nutrient rich environment of jelly fish. Jellyfish that learned to spiral up and down to reduce congestion. Adding that motion to the pond is like a mild centrifuge, just right for giving evolution a new partition.

It is the same idea of dimensional increment. Our biology manages a stable 4D system and bounces up against five, now and then. Our biology is mostly 4 tuple relative prime, but we did get five fingers.
