Recent research by scientists has revealed a gene that could be the key to understanding circatidal and circadian rhythms in animals. This gene, called “period,” plays an important role in the body’s internal clock and may be the key to understanding why some animals have adapted to living in tidal settings, such as along coastlines. The discovery of this gene provides a better understanding of how animals adapt to changing environments and could have applications in the medical world. This finding could potentially lead to treatments for conditions such as jet lag or other sleep disorders.
