In order to create a bilateral body form the brain and the rest of the body had to mirror. By mirroring it created a problem of coordination between hemispheres. this coordination problem required a criteria for priority. That priority resulted in prey in time,( right dominant) and predator over time (left-dominant), where the lateral integration of hemispheres in the right dominant is higher for more perception, and the longitudinal integration in the left dominant for more rapid reaction and action.
The female bias to empathizing evolved from the need to nurse, and then spread to the male. The result was a greater incentive to cooperate regardless of sex.
That’s just a sketch.
I can describe everything from the neural tube forward to the entire body, and from the formation of neural stem cells to the organization of sex differences in the brain.
There is nothing meaningful left except increases in precision.
