The Maya people of Guatemala are among the shortest people in the world. Men on average hover a few inches above 5 feet and women a few inches below. But if they move to the United States as children, the Maya grow taller. That extra growth carries to the next generation: Maya children born to Guatemalan immigrants in the United States are roughly four inches taller than their peers in Guatemala, research by biological anthropologist Barry Bogin shows. Some of that gap disappears as children reach adulthood, but even then, Maya people in the United States are still taller than people in their native country.
