I am halfway through Dan Simmons 'Fall of Hyperion' and I was wondering whether there are any expert opinions on how human physicality would change upon living in zero-g.
In the Hyperion novels the Ouster race is described as being 3 meters tall, thin, having some sort of tail, and having feet that can grip like hands.
To me it seems absolutely absurd that humans could evolve so much in the space of 4 or 5 centuries. I would guess that people would naturally grow taller, maybe a couple of foot or so, and that people would be very thin and have very little muscle mass, but the evolution of a tail and gripping feet I think is a step too far!
Does anyone know if any scientists or whatever have ever published any theories on this. Or even point out what I have missed (such as the Ousters genetically modifying a generation of children or something, which would make more sense to me).
