Chimpanzee groups fight each other
I read in Frans de Waal book that two groups of chimpanzees sometimes fight each other. Is it true that two groups of chimpanzees sometimes fight each other, with one group attacking individuals? So a group of male chimpanzees attacks single chimpanzees. 2A02:908:424:9D60:979:D36A:5559:FF19 (talk) 19:24, 20 May 2023 (UTC)
