BK channels carry roughly 10 times the current per molecule of other potassium channels, and since the early 1980s no one could say why evolution built them that way. Simulations and evolutionary modeling now point to spike timing as a probable pressure, with conductance highest in mammals and birds and lowest in mollusks.
