Turns out that human politics aren't far advanced from chimp politics:
Nepotism is known to be important in chimpanzee society, but male chimps' ability to cooperate extends beyond family connections, new research reveals...
Extensive cooperation among non-relatives suggests that chimps do it for selfish reasons, with the expectation that favours will be reciprocated, says Langergraber. Human societies use cooperation with similar motives – another behaviour shared with our primate cousins.
It's only a matter of time before scientists expose elaborate jungle kick-back schemes.
