How do reindeers cope with the seasons?
Well, researchers have discovered that the animals did not possess what is called the "circadian clock" that influences processes including the sleep-wake cycle and metabolism, usually based on a 24 hour rhythm.
Apparently, it could be the case for most animals living in polar extreme conditions, this basically helps them not get depressed every autumn before the arrival of extreme weather conditions. It also avoids them go binge-drinking to forget winter is on its way. Clever things!
