Question

The strongest support for the evolutionary purpose of sleep is that it helps conserve energy. During periods of sleep, an organism's metabolism and energy use decrease, which helps them conserve precious resources. Additionally, studies have shown that sleep deprivation can lead to a reduction in metabolic rate and decreased energy levels. Other hypotheses, such as reduced exposure to predators and restoration of bodily resources, also have some support but are not as strongly supported as the energy conservation hypothesis.
