How Smart Are Animals, Really?

The video explores the complexity of defining and measuring animal intelligence, highlighting popular tests like the pointing and mirror tests. It critiques these tests for their relevance and small sample sizes. A systematic study on self-control across 36 species is discussed, revealing that absolute brain size correlates with intelligence. The study suggests that intelligence may have evolved to help animals manage varied diets rather than social complexities. The findings challenge previous assumptions about brain size and intelligence, offering new insights into the evolution of cognitive abilities.
