Manson and Wrangham (1991) suggest that it is resources of
reproductive interest that determine the causes of intergroup
aggression. This may include material resources.
Goodall (1986 p.505) reports that after the Kahama community at Gombe
was annihilated by the Kasakela males their community range was
annexated by the latter.
Makes you wonder about ultimate causes.
