Always Quote by Michael Rosbash
“It was always intriguing that flies had two peaks of activity, in the morning and evening, with a siesta during the day and not very much activity at night. There are several ways to explain that, but one possibility was that there were two clocks running - one governing the morning peak and one governing the evening peak.”
About This Quote
Source Research: Drosophila circadian rhythm studies, 1990s
Flies show two daily activity peaks, suggesting separate internal clocks for morning and evening, with reduced daytime activity and minimal night activity.
In simple terms: Flies have two daily activity periods, likely driven by two internal clocks.
Key Takeaway
Consider how multiple internal timers can regulate behavior.
