When we talk about evolution we come across the process of natural selection. Genetic variation is always required for the natural selection. A change or variation in the genes may help the individuals in a population to better adapt to the environment. Such changes may be brought by mutations or random mating in the population. Such variations help in the survival of the population by allowing them to adapt to changing environmental conditions.

Acting as levers for movement is a function of ______.
sashaice [31]

Acting as levers for movement is a function of: bones.

Movement can be defined as a process through which several skeletal muscles in the body systems act together as a group, in order to cause a change in the motion of a body part.

Basically, bodily movement are produced when skeletal muscles exerts a force on the tendons, which in turn pull on the bones (levers) and other supporting structures such as the skin.

In the body of living organisms, bones act as levers for movement by enhancing limb speed or power of limb movements while joints act as a fixed point of movement (fulcrum).
