Growth curves for different human populations. Pygmy women [Aeta (black triangles), n = 214; Biaka (13) (gray triangles), n = 157; and Agta (14) (open triangles), n = 83] grow at rates bellow the 5th U.S. percentile (intermediate solid line), and their growth curves level off early at ≈13 years old, reaching an adult body size equivalent to the percentile 0.01 (lower solid line). African Pastoralists (16) [Massai (open squares) and Turkana (black squares), n = 228], also grow at slow rates compared with U.S. subjects but extend their growth trajectories and achieve final height equivalent to the U.S. 50th percentile (solid upper line).
