In this episode, we examine how every animal has what could be called a sense of rhythm û the human animal included. To give an obvious example, there’s our internal body clock which responds to the so-called Circadian rhythm. That’s the 24 hour night and day cycle. Species: Lizards, Cicada, Bears, Acrtic Ground Squirrel.
