How Gravity Affects Life

Gravity can change the way things evolve. On a large, very dense planet there will be a larger gravitational force. Any lifeforms there will be denser, and much more heavyset. They will possibly be small in size. They will need that to withstand the great pressures on the surface. On a small planet, the size of Mercury or Mars, lifeforms will be more exotic. Aliens may be larger, though have much less density. Their bodily functions will vary, depending on the amount of gravity. On a light-gravity planet life forms may have a porous skin, so they can move faster. How do you think gravity has affected evolution on our planet?
