A new study has led archaeologists to believe that the world's first war was Sudan. Researchers from France and the UK have re-examined 61 human skeletons a site at Jebel Sahaba the Nile Valley in Northern Sudan. The skeletons are 13,400 years old and were uncovered the 1960s. For decades, scientists believed the millennia-old humans were killed a one-off massacre. New research injuries sustained the early humans revealed that they were killed during a longer war that took place several years. The skeletons are now regarded as evidence the earliest example of organized warfare between humans. Furthermore, the war was probably triggered climate change.
The researchers conducted a deeper investigation injuries the skeletons found at Jebel Sahaba. The scientists said the injuries were as a result weapons such as arrows and spears. They were likely sustained during a series conflicts or battles over several decades. The researchers believe conflicts arose as rival tribes competed food and water that were limited supply because dramatic changes in climate 11,000 to 20,000 years ago. At this time, ice covered a lot the Northern Hemisphere. This caused flooding and major changes to the availability farmland. A researcher said: "These changes were not gradual all. People had to survive these changes, which were brutal."
