3.6 Implications for Humans and Future Research

summary

There are different ways of comparing brains with regard to size, neuron density, body mass, metabolic rate, and longevity.
There is order to scaling and it allows us to make predictions.
Professor Herculano-Houzel’s brain soup technique allows us to conclude that humans are not special after all. Humans’ brains have just as many neurons as one would expect from a primate with a brain of that size, and humans live just as one long as one would expect from an animal with that many neurons. It is important to make the right comparisons.
