Biological Clock
The biological clock of the human body is the internal mechanism that regulates our sleep-wake cycle, also known as the circadian rhythm. This clock is influenced by external factors such as light, temperature, and social activities, and plays a crucial role in determining when we feel alert or sleepy. Disruptions to this clock, such as jet lag or shift work, can have negative effects on our health and well-being.
To develop a molecular clock, you need to identify a reliable set of molecular sequences (such as DNA or protein sequences) from different species. Additionally, you require a well-calibrated timeline of evolutionary events, often based on fossil records or known divergence times. By comparing the genetic differences and correlating them with the time since divergence, you can estimate the rate of molecular evolution and construct the molecular clock.
