For our ancestors, nighttime was dangerous -> to escape from predators
they couldn't finding food themselves -> bodies slowed down to conserve energy
most experts reject this idea because sleeping leaves animals vulnerable and defenseless
sleeping limits productivity

neuroplasticity
brain's ability to change and adapt in response to experience
change both functional aspects and structural aspects
sleep is necessary for the brain to make structural changes
explains why babies and young children require a lot of sleep
sleep is the price we pay for brain plasticity
