Chimpanzee ready for war, Antwerpen Zoo
The Antwerpen Zoo has a group of chimps from various walks of life. Some were born in captivity, others used to be held as a pet. As a result of the mixing of these chimps, a true chimp war has erupted, an epic power struggle within the group, paired with violence. Such a war does not require a lot of governance from humans, it is a natural balancing act where violence is not used to kill, it is used to establish hierarchy only.
This particular chimp to me looks like a victor of the war.

The common chimpanzee, also known as the robust chimpanzee, is a species of great ape. Evidence from fossils and DNA sequencing show both species of chimpanzees are the sister group to the modern human lineage.
