I don't think height evolved. I think height is a characteristic of everything. At least everything we can see with our eyes, even if aided by a microscope. Maybe it's not a property of matter, but a characteristic of mass. Something like that? So everything has height. Things evolve with greater or lesser height, depending on how the matter is arranged. But it's not the height that evolves.
This is different from something like metabolism. Most matter doesn't metabolize at all. Mobility is another example. Intelligence is another.
If panpsychism is the answer, then consciousness didn't evolve.
