A study published last week in the scientific journal Genome Biology and Evolution suggests a possible link between your attitude toward waking up in the morning and your genetic makeup. According to the study, some of us carry genetic variants with us that influence how we cope with our daily cycle. The study identified a link between "morning people"—that is, people who cope more easily with early wake-ups—and genetic variants originating in Neanderthals. We used ChatGPT to understand how this happened.
After the migration of Homo sapiens from Africa about 70,000 years ago, descendants born from the culture with extinct relatives, including Neanderthals, created genetic differences that helped cope with the environment in which they met north of Africa. The study identified 246 genes related to daily menstrual behavior. Analysis of these genes by artificial intelligence tools showed that people who inherited Neanderthal variants were more likely to be morning people.
According to the study authors, the benefit of coping with early hours in the morning for survival in northern African regions is unclear. One hypothesis is that morning people cope better with varying light levels. At the same time, the researchers note that people's sleep habits do not depend only on genetics, whether Neanderthal or not. Environmental and cultural factors also affect your ability to cope with morning.
