Don’t mean to be too bong-rippy here, but I honestly think it comes from a lot of people (and Western philosophers/critical theorists in the past) undervaluing the awesome but gentle power of persuasion and implementing systems of social consensus, and overvaluing ideals of “power” or “control”.
It's simply because 10,000 years of society doesn't erase 2.5 million years of evolution (plus, hundreds of millions of years going back). We're primates, and primates establish hierarchy primarily from "might makes right".
No, we're equally related to both. They're both first cousin species to us. Chimps are just more famous because they're less endangered and so more experimented with.
However, bonobos are also hierarchical. They're just more flexible about power, with female alliances dominating solo males.
