so is the frontal lobe of the brain the essence of free-will ?

Let's say that there's an aspect of existence we call free will... volition.
The frontal lobe would have to be involved in thinking about it.
But we recognize volition in creatures which don't have frontal lobes... or even brains. What we're seeing is movement, the source of which is inside the creature.
So a firecracker would be an example of that, except we don't accept firecrackers as
living creatures. We assume that animal creatures move according to what's called final causes... which means purposefully. So however purposeful a firecracker's movement might look, we won't accept it as volition.
So why isn't bamboo understood to have volition? It's alive and the source of its movement in terms of growth is within it. And there's a final cause: to access light for photosynthesis. So we answer: if a bamboo root comes to a rock, it doesn't make a choice, it grows however it can.
An earthworm, on the other hand doesn't seem to make choices exactly... doesn't it move pretty much like the bamboo root? ... however it can?
The thing is an earthworm and go in one direction and then back up and go in a different one. And we immediately know: volition. I'm going to say that however technical we get in defining volition, it's always going to come down to intuition. It's something basic.
