When did the war between humans begin? Probably, there have been wars and violence in the name of something since the time of man. The 61 skeletons found in the  Nile Valley in the 1960s are now considered the first evidence of organized warfare between humans. The new findings are based on a study of skeletons. The skeletons found by Jebel Sahaba are estimated to be at least 13,000 years old. Evidence of injuries in it suggests that brutal clashes took place that day. Injuries were mainly found from weapons such as spears and arrows. This new study, published in Scientific Reports, shows that this is not a one-time massacre as previously thought. Instead, they may have been killed as part of a series of atrocities over the years. The study also suggests that there may be important climatic and environmental factors.

The study also found that beatings, sudden attacks and ambush attacks may have been among these men. A new study has found that when these skeletons are examined earlier, they go unnoticed. It was a community of hunters and fishermen. According to Isabel Provocur, a researcher at the French National Center for Scientific Research at the University of Bordeaux, men, women and children are victims of violence.

The only difference is that women are more likely to have injuries on their wrists and men on their hands. It is believed that women used weapons for self-defense but men defended them with bare hands. It is also believed that children have suffered severe head injuries. Evidence of injuries suggests that the riots may not have been committed by members of the same community or by domestic violence. Researchers have identified and examined more than 100 new injuries. That includes the good and the bad. Many of the injuries from the stone weapon in the bones are still obvious. 40% of individuals had both healed and non-healing injuries. Researchers also say that cats need to be included in any precautionary measures against the virus. 

Therefore, it is thought that humans may have fought each other when climate change caused food shortages. These changes occurred 11,000 to 20,000 years ago. It must have been the end of a period known as the last ice age. Glaciers then covered most of the northern hemisphere, destroying the Earth's climate. All of this is thought to have led people to fight each other for resources. Isabel said the Paddy Valley may have been a refuge for a wide variety of people who once lived in a vast area. Extremely dry weather led them to the river, where it was easy to hunt and fish. There was also evidence of heavy flooding in the Nile at this time. Isabel says they may have had to survive this ordeal.
