Why Pets Have Surprisingly Small Brains

The video explores how domestication has led to a reduction in brain size across various animals, such as ducks, cats, and pigs. It highlights the correlation between brain and body size, noting that domesticated animals have smaller brains compared to their wild counterparts.
