Action potential: why called “depolarization” when polarity is reversed, not removed?

During an action potential, the voltage shifts from the resting potential of -70 mV, to +30 mV, to then fall return back to the resting potential again of -70 mV. This reverse of the polarity, what is the reason it came to be called “depolarization”, as in, removed polarity?

What would the evolutionary explanation on why sons inherit intelligence/IQ from mothers instead of father?

Do the mother's genes determine the sons' (heredity) intelligence more than the father's? This one says it is not This one says it is https://www.independent.co.uk/news/science/children-intelligence-iq-mother-inherit-inheritance-genetics-genes-a7345596.html Say it is.
