Human population size is constrained by body mass and metabolic needs
the verdict
SUPPORTED
the evidence backs this
confidence 80/100
Multiple studies support the principle that organismal body mass and metabolic requirements impose fundamental constraints on population density, geographic range size, and ecological scaling.
