In humans, the family prevents infanticide. Next to language, the core family, consisting of a mother, a father and children, is the greatest difference between us and other primates.

The primate laugh is given in playful contexts, and as such has a strong similarity to the human laugh.

Perhaps it's just me, but I am wary of any persons whose belief system is the only thing standing between them and repulsive behavior.

We are by far the most contradictory of all primates. An animal with this much internal conflict has never lived on this earth.

We are territorial, power-hungry and even more brutal than chimpanzees.

Humans became easy prey when they moved from the forest to the savanna, which deprived them of the option of climbing trees to flee predators. This shift made it necessary for the men to actively protect the women and their babies. Only as a result of this protection were women able to give birth in shorter intervals, perhaps once every two or three years. This meant that they could produce offspring about twice as frequently as apes. I would be willing to bet that this rapid reproduction is one of the reasons why we dominate the world today, and not the apes.
