As biologist John Timmer notes at Ars Technica, some life forms appear much more intelligent than others despite having brains of roughly the same size: Animals with very different brains from ours—a species of octopus and various birds—engage with tools, to give just one example. It seems intuitive that a brain needs a certain level of size and sophistication to enable intelligence. But figuring out why some species seem to have intelligence while closely related ones don’t has proven difficult—so difficult that we don’t really understand it. John Timmer, “Brain size vs. body size and the roots of intelligence” at Ars Technica (July 12, 2022) As he points out, some things we might expect to be true — puzzlingly —…
