When do people know how to wear clothes?

Scientists discovered that people began dressing 170,000 years ago at a time when people went out of Africa and migrated to other regions.

According to a new study of the evolution of lice, scientists found that people began dressing 170,000 years ago at the time humans came out of Africa and migrated to other regions.

Since clothing apparel cannot exist for a long time, the use of traditional archaeological methods to determine the time when people began to wear clothing was impossible.

Therefore, Dr. David Reed, a mammal researcher at the University of Florida and his colleagues, turned to studying the evolutionary divergence of lice as they shifted from human scalp down. clothes from which determine when people begin to wear clothes.

' We want to find another way to determine when people start dressing. Because we know that lice in clothing only appear when clothing has appeared in people's lives , 'said David Reed.

The live lice on human scalp (also known as lice) are the earliest lice. Later, when people knew how to wear clothes, this louse began to differentiate into two, a species that switched to living on the skin of the body, also known as clothing lice.

About 100,000 years ago, people began migrating to cold and higher areas. This also means that, from earlier 70 thousand years, people began to wear clothes.

This study has demonstrated that humans have a very long time without clothing and body hair to keep warm. Previous studies have confirmed that the time when the human body began to shed all its hair occurred about 1 million years ago. But people only start to wear clothes when the hair on the body has fallen out.

Earlier, in 2003, a study of clothing lice by Mark Stoneking and a number of scientists at Max Planck Academy, Germany discovered that people began to wear clothes from 107 thousand years ago. .

However, based on new data and methodologies, University of Florida experts discovered that lice and lice began to differentiate 170 thousand years ago. That is, from this moment, people start to wear clothes.

Ian Gilligan, of the Australian National University, said: ' The results of this study will help people learn more about the evolution of people as well as the way people migrate. Modern people can start dressing on a regular basis to keep warm when they first face the Ice Age . '

Although lice are a species that gives us so many unpleasant things, in science, they are an important thing. By studying the change of lice, people know the change of the host they live on. Here, the change of lice living on the human body helped to find out when we knew how to wear clothes.

In addition, the study of lice can also create opportunities to learn about how they change and invade new hosts, along with the types of illnesses that accompany them. Thus, we will know more about the epidemics that once raged in the past.
