"Tallest in the World: Native Americans of the Great Plains in the Nineteenth Century," Richard H. Steckel and Joseph M. Prince, 2001.
They were the tallest human beings alive on earth at the time. There's a study in 2001 called tallest in the world, and they looked at original source data where they were actually measuring a bunch of Native Americans on the Great Plains, and these guys were largely meat eaters. They were eating buffalo year-round. They were the tallest human beings alive on Earth at the time. The really interesting part of that study was says very clearly that the young men were the shortest in the entire tribe. The fathers were taller. Grandfathers were even taller. If we did the study 100 years ago, this would be way different, this average height would be well above 6 ft tall. And when the study was done, when those measurements were done, was after the bison were wiped out and they were put on reservations. So that was that transition period. You saw it in three generations.
