where is the biological clock in our body? how does it effect us?
Hi Andy, why do you say the circadian molecules are not conserved? Many are, cryptochrome for instance is conserved from plants to animals http://www.ncbi.nlm.nih.gov/pubmed/13678578. A brief insight review article (not very recent, but to the point): Circadian rhythms from flies to human.Andy Resnick said:Circadian rhythms continue to be an active area of research- it is difficult to quantify influences of genes vs. adaptation. Different organisms (fungi, bacteria, insects, vertebrates, etc) all have oscillatory networks of molecules, but the molecules themselves are not conserved (see for example, Vinod Kumar, "Biological Rhythms"), and the rhythm can show great variability in the face of environmental changes.

The biological clock, also known as the circadian rhythm, is a natural 24-hour cycle that regulates various physiological processes in our body, such as sleep-wake cycle, hormone production, and body temperature.
The biological clock is controlled by a group of nerve cells in the brain called the suprachiasmatic nucleus (SCN). The SCN responds to light and dark signals from the environment and sends signals to other parts of the body to regulate their functions.
Our biological clock can be affected by various factors, such as exposure to light, physical activity, meal times, and social interactions. Changes in these factors can disrupt our circadian rhythm and lead to sleep disorders and other health issues.
Yes, our biological clock can change due to external factors, such as traveling to a different time zone, working night shifts, or aging. These changes can disrupt our natural circadian rhythm and cause jet lag, fatigue, and other health problems.
Maintaining a healthy biological clock is crucial for our overall health and well-being. Disruptions in our circadian rhythm can lead to sleep disorders, mood changes, and an increased risk of chronic diseases, such as obesity, diabetes, and cardiovascular disease.
