- Retric 6y agoIt’s important to separate changes across evolutionary timescales with individual mutations. Brian’s have a metabolic cost which promotes efficiency over time, but efficiency is just one of many relevant factors. A whale has significantly less relative metabolic cost per Lb of brain than a mouse. Further, individual mutations may be a net negative.
