They found that nearly all the skulls belonging to people who lived more than 80,000 years ago show evidence of testosterone levels that were far higher than any modern-day human's. These high hormone levels may have made social cooperation and community-building more difficult.

Do lions have testosterone?

In the wild, male lions start experiencing a rise in testosterone at approximately 2 years old, which signals that the male is becoming sexually mature and it is time for him to leave the pride and search for mates.
