The same applies to archaeological data representing the cemeteries of forager and farming populations, whose putative gradient of mobility from nomadic to sedentary (see below) closely coincides with the expected birth rate estimates. This is the message contained Fig. 4 3D representation of demographic density (proxy for fertility), accounted for by energy expenditure (mobility, from 0 = nomadic to 7 = sedentary) and energy intake (diet from (a) hunting, (b) aquatic animals, (c) agricultural produce) with the relative metabolic load model applied to Jorgensen's sample (1979 Jorgensen's sample ( , 1999 of western North American Indians on first European contact.	./cache/cord-016310-7655ggxz.txt	./txt/cord-016310-7655ggxz.txt
