An action potential is an excitatory presynaptic nerve. An EPSP (Excitatory postsynaptic potential) takes place in the dendrites of the postsynaptic nerve. This spreads passively to the axon hillock. Depolarization of this region opens voltage-gated ionic channels. Sufficient membrane depolarization to threshold opens enough to these channels to produce an action potential.
Non myelinated axon; the currents associated with the action potential spread to the depolarized region of the axon.
In myelinated axon; the currents associated with the action potential spread to the next Node of Ranvier.
The action potential travels down the axon to the axon terminals.

It might. it might because if you think about if they discovered if we came from (lets say something funny like aliens) and thy found cells that matched and they would have t do more research about it but would most probably change their theory.
