The Dutch are, on average, the tallest people on earth and scientist Gert Stulp is trying to figure out why. The Dutch weren’t always tall. In fact, in the 1800’s they were shorter than Americans on average. Now, the average Dutch male is over six feet tall.
I’m not sure that there’s any real advantage to being tall, and Sergio Cortes isn’t so sure either. It looks impressive and helps on the basketball court, but beyond that it doesn’t do much for an individual. It’s worth studying why some societies are taller than others, though. The more we know about how evolution works in different societies the better. I also wonder if humans as a whole will continue to grow taller in coming years.
