Ancient baby boom holds a lesson in over-population

Researchers have sketched out one of the greatest baby booms in North American history, a centuries-long ‘growth blip’ among southwestern Native Americans between 500 to 1300 A.D. It was a time when the early features of civilization — including farming and food storage — had matured to where birth rates likely ‘exceeded the highest in the world today,’ the researchers write. A crash followed, offering a warning sign to the modern world about the dangers of overpopulation.
