Document Summary
Organisms from the same family but more complex eyes for each. Our planet we have diff environments (darkness to bright environments) Organisms that live there have to adapt: adapting to colouration, circadian rhythm. Cr is the behavioural pattern within a organism of a 24hr time range. Cr is a clock set by the photoreceptors you use according to light and dark: eg. If your on canadian time and your on european clock, sleeping schedule is not right. Because body is set to a certain time to wake up and sleep: birds hibernating in winter and return in summer. They know the weather and know when to fly back. Birds have a daily cycle as well as yearly cycles while humans are 24hr clock only. Keeping track is important because they give a lot of info: plants are efficient because they make there enzymes at night because they can absorb the energy during the day.
