In birds, big brains aren’t associated with living in large social groups – instead, they’re linked to long stints of parental feeding.
Using a new equation based on today’s primates, scientists can take a few molar teeth from an extinct fossil species and reconstruct exactly how fast their offspring grew during gestation.
The way human brains develop is special – but not quite as special as you’d like to think, if we consider Neanderthals as well.
Axolotls are amphibians known for their ability to regrow their organs, including their brains. New research clarifies their regeneration process.
Some animals, such as California sea lions, have small brains relative to their body size, but are still impressively intelligent, showing brain evolution is even more complex than it appears.
