Answer:
Mass does not affect gravity and distance has an indirect relationship.
Explanation:
The equation for gravity is, g = 
where, G = gravitational constant
M = mass of the planet
R = distance between the bodies (object and center of planet)
so, gravity depends on the mass of planet, not on mass of object
and is inversely proportional to sqaure of distance.
Personally, I think since all the changes in the world are affecting the natural environment adaptive traits are important so that they can help maximize its reproductive success so its species can survive.
