Paragraph 1
A new
has led archaeologists to believe that the world's first
was in Sudan. Researchers from France and the UK have re-examined 61 human
from a site at Jebel Sahaba in the Nile Valley in Northern Sudan. The skeletons are 13,400 years old and were uncovered in the 1960s. For
, scientists believed the millennia-old humans were killed in a one-off
. New research on injuries sustained by the early
revealed that they were killed during a
war that took place over
years. The skeletons are now regarded as evidence of the earliest
of organized warfare between humans. Furthermore, the war was
triggered by climate change.
