the sound of morning chickens (Indonesia steemit Community)

Previous studies have shown that a myriad of animal behavior is generally driven by an internal clock in its body that recognizes time. Suppose that at night some animals duck themselves in swamps or puddles, even the fish inside the cave use circadian clocks to tell time.

"The sound of a rooster crowing is a symbol or a sign that the dawn has arrived. Many people in various countries believe it, but this research has not been clear enough to prove that the rooster actually is crowed because it has a time sensitivity in its body or just a response to stimulate its external stimuli.

Because all-day stimulation - like flashing a car's lights, will trigger a rooster to crow every time. It is also suspected to be the reason why the rooster continues to crow because of the light that leads to the rooster. To find out, Yoshimura and his colleagues conducted research and placed 40 roosters in a constant-light setting, then recorded as they crowed.

Sure enough, in fact the rooster crows not only at dawn. Rooster also crows because it responds to light and as a way to communicate with other chickens, but their crowing behavior is much stronger at dawn. As a follow-up, to determine the genetic basis of the sound of other animals.
