Muscle cramps result from an involuntary contraction of a skeletal muscle. Overuse, prolonged exercise without proper conditioning, and fatigue are common causes of muscle cramps. In addition, dehydration and depletion of electrolytes, including magnesium, calcium and potassium, can lead to muscle cramps.
The relationship between intelligent design and science has been a contentious one. Intelligent design (ID) is presented by its proponents as science and claims to offer an alternative to evolution.
Implicit in the intelligent design doctrine is a redefining of science and how it is conducted (see theistic science). Wedge strategy proponents are opposed to materialism, naturalism, and evolution, and have made the removal of each from how science is conducted and taught an explicit goal.
