The eyes have it: Men do see things differently to women
The way that the visual centers of men and women’s brains works is different, finds new research published in BioMed Central’s open access journal Biology of Sex Differences. Men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors.
Could be as simple as humans get so many neurons and need to allocate them across total set of stuff needed for life.
Women need to devote a good % of those to pregnancy mode, while men just have normal mode.
Therefore some functions may have to deal with reduced neuron allocations, because the ‘missing’ ones are required elsewhere.
Obviously a simplification of things, but with only one way of needing to be men optimize to a different configuration with a different allocation of neurons to match.
this is definitely the simplest, and probably most likely, though possibly not super accurate answer.
