Final answer:
Humans' social behavior is more similar to chimpanzees than previously thought.
Step-by-step explanation:
The social behavior of humans is more similar to chimpanzees than previously thought.
Humans' closest primate relatives are chimpanzees, sharing 99 percent of their DNA with humans. Both species exhibit gender-related behaviors, but chimpanzees are male-dominant and their groups are intensely hierarchical. This similarity suggests that our social behavior may have some roots in our primate ancestors.
