Animals face strict physical size limitations due to scaling laws of metabolic rate and skeletal support
the verdict
SUPPORTED
the evidence backs this
confidence 84/100
Multiple studies demonstrate that animals are subject to strict allometric scaling laws regarding metabolic rates, skeletal support, and biomechanical limitations as body size increases.
