as much as someone is willing to give you for it.
It enabled animals to move more easily on land.
Evolution of paired limbs was one of major developments . Similarly development of jaws , Amnion etc are also major developments .
In simple terms - evolution ! Snakes & lizards share a common ancestry. While lizards chose to keep using their limbs, snakes evolved to depend on their external limbs less over time. Eventually, over many thousands of years, their limbs grew shorter until they disappeared completely. The only evidence their limbs existed - is remnants of bone in their skeletons.

Body parts that are reduced in size with no apparent function would be vestigial limbs. Evolution could be at the root of the development of vestigial limbs. A good example would be a T-Rex with his tiny arms.
Absolutely! Over time the limbs on compound bows will weaken and possibly crack which will eventually result in a break. Also, strings and buss cables will wear and break. As a rule of thumb, strings and cables should be changed approximately every two years. Limbs will have to be changed as soon as cracks form.
They have the same common ancestor if you go back far enough in time.
