Biological Clocks: Museum

Time Matters: Biological Clockworks

The existence of biological clocks has been suspected for centuries, but for most of human history little was known about how they worked. In the last few decades — with enormous advances in molecular biology and genetics — the detailed chemical workings of biological clocks have begun to be understood. This exhibit explores the inputs, outputs, and mechanisms of biological clocks with a primary focus on circadian rhythms—circadian being a term that biologists use to describe biological mechanisms on the scale of a day, from the Latin meaning "about a day."
