247 Big Brains Ain't Free
Episode 247
Tuesday, 12 May, 2026

Big brains are very useful, but they cost ENERGY and RESOURCES, at least for mammals and birds. Now a new study has shed light on what determines whether reptiles and amphibian species have evolved to be clever, or nice but dim. We also discuss cannibalism by snakes, which is actually pretty common albeit difficult to document due to their secretive lifestyles.
