Maybe this is part of the great filter? No planets that have lower gravitational force are hospitable to intelligent life and all planets that are hospitable to intelligent life have higher gravitational force. We are just incredibly lucky to lie just one the boundary.
I am not suggesting that gravity causes intelligent life to evolve but that the overall characteristic of such planets is such that etc.

Doubtful. You can lift a seed colony up to where launch is easy.
