Part 2 Chronobiology: The Clocks That Make Us Run
The assigned reading for this chapter had a lot of intricate twists and turns; I wanted to continue to talk about the circadian rhythms. As we stated in the last weekly post According to Dictionary.com, the Circadian rhythm is “A daily cycle of biological activity based on a 24-hour period and influenced by natural variations in the environment, such as the alternation of night and day. Circadian rhythms include sleeping and waking in animals, flower closing, and opening in angiosperms, and tissue growth and differentiation in fungi.” Now there are a few animals that do not abide by the cycle of awakening by the natural rising of the sun.
According to Bartford (2017) “Two marine animals have tidal and monthly timekeepers that work independently of the daily cycle. The Bristol Worm being the first, and it actually runs of the lunar phase, and the Sea Louse Eurydice actually has two independent biological clocks. The Sea Louse the day and night cycle and is also in tune with the tides.
I believe that having very few animals that do not conform to the circadian rhythm is truly an interesting factor in that the majority of creatures and the human species operates around the rising of the sun. The species that does not operate by the rising of the sun gives us a better look at the innovate way time is being used. As I reviewed Rifkin (1987), I found that there are also circannual rhythms. The circannual rhythm is based on the seasons’ change in relation to animals hibernating. The rhythms are very unique and certainly innovative.
In conclusion, I would have to say that time yet again as proven to be one of the most innovative pieces of the world. We as a society may have ideas of what life holds, but there are still quite a few mysterious that we don’t know or understand about life.
