Population continuity or population change: formation of the ancient Egyptian state.

abstract：:Compared to most quadrupedal mammals, humans are energetically inefficient when running at high speeds. This fact can be taken to mean that human dipedalism evolved for reasons other than to reduce relative energy cost durding locomotion. Recalculation of the energy expending expended during human walking at normal sp...
