Great ape nature similarity

I wonder how much human society/culture/nature (with all its complexity and "advancement") is really not that much different than chimps/bonobos:

The common chimpanzee has a troop culture based on beta males led by an alpha male, and highly complex social relationships. The bonobo, on the other hand, has egalitarian, nonviolent, matriarchal, sexually receptive behaviour. Bonobos frequently have sex, sometimes to help prevent and resolve conflicts. Different groups of chimpanzees also have different cultural behaviour with preferences for types of tools. The common chimpanzee tends to display greater aggression than does the bonobo.
