Discusses the theory of different brain sizes among species, which two scientists now say they think is related to ecology, or adaptation. Other scientists support the theories of developmental timing or genetic constraint to explain the differences in brain sizes, known as the taxon-level effect....
Despite the stereotype of dinosaurs with "walnut-sized brains", many were extremely intelligent, and perhaps the most intelligent organisms on Earth at the time. They may even have been more intelligent than many mammals that came after them....
And what we found is that because neurons are so expensive, there is a tradeoff between body size and number of neurons. So a primate that eats eight hours per day can afford at most 53 billion neurons, but then its body cannot be any bigger than 25 kilos. To weigh any more than tha...
The effort to give robots AI brains is revealing big practical challenges—and bigger ethical concerns
Washburn’s key assumptions — that women walk less efficiently than men do because their pelvis is wider for childbirth. But in 2015, after studying volunteers walking on treadmills, Dr. Warrener found that having a wider pelvis did not create a bigger demand for oxygen. “The data came ...

My vulnerability scared me. I wasn’t used to students being bigger than I was. Big and black . . . . No. No—just big. What had started it? Why had I lost control? My failure as a teacher scared me more. Maybe the incident hadn’t really been a threat, just a test. After ...
The 21 vocal-learning species had slightly larger brains, relative to their body size, than the two who weren’t. Jarvis says it’s possible these big-headed birds packed more neurons. One question left unanswered is why there’s such a strong relationship between problem-solving abilities ...
