摘要
Humans, like all organisms, are subject to fundamental biophysical laws. Van Valen predicted that, because of zero-sum dynamics, all 族群s of all 物種 in a given environment flux the same amount of energy on average. Damuth's 'energetic equivalence rule'supported Van Valen 's conjecture by showing a tradeoff between few big animals per area with high individual metabolic rates compared to abundant small 物種 with low energy requirements. We use metabolic 縮放律 theory to compare variation in densities and individual energy use in human societies to other land mammals. We show that hunter-gatherers occurred at densities lower than the average for a mammal of our size. Most modern humans, in contrast, concentrate in large cities at densities up to four orders of magnitude greater than hunter-gatherer
