Well, this study could make some people happy, out of a simple reason: it shows that people need partying since ancient times.

Scientists suggest that these gatherings in small or larger groups, animated by a collective rhythmic movement, were for our ancestors a way to connect, communicate and survive. In addition, those who possessed the ability to coordinate and rhythm might have had an advantage in terms of evolution. What we moderns understand by partying represents to some extent what the French sociologist Emile Durkheim called “collective effervescence”.

Durkheim explained that people feel a kind of electricity when in contact with others. The sensation is then transmitted, and people will feel a collective emotional excitement, explains Paul Carls from the University of Montreal. Also, parties do not come only from the behavior of our forefathers and religious rituals. As ancient rituals needed a shaman to create this atmosphere, today we have DJ in the club, says Dimitris Xygalatas, an anthropologist at the University of Connecticut, quoted by Science of Us.

In 2006, a study by researchers at the University of Reading suggests that our ancestors didn’t dance for fun, but to survive. This activity was a way to establish relationships, and scientists wanted to see if an advantage is evolving. The team analyzed DNA from blood borne dancers and compared them with those of people with “two left feet”. They found out that two genes linked dancers with advanced communication skills. In addition, higher levels of serotonins, which are always a sign of a better mood.

In addition, our ancestors danced and attract potential partners, 1.5 million years ago, explains Steven J. Mithen, an archaeologist at the University of Reading. Of course, now we do not necessarily need to go to parties and show our dance movements to survive or to find our partners, but it certainly helps. In addition, even dancing makes us happier.
