When a male chimp reaches 15 years of age, they start bossing and brutilizing female chimps. The only other species known to do that are humans.

I just thought this was a fun clfact because out of the millions and millions of species out there, ONLY 2 boss and criticize their females…and those are CHIMPS and HUMANS. **mindblooowwwwnnnn* you learn something new everyday!
