Is there a correlation between brain size and the diversity of social behaviours exhibited by a species? In cetaceans, it seems that there is, reveals a study published this month in the journal Nature Ecology and Evolution<\/em>.<\/p>\n

By comparing the size of the brain, the diversity of social and cultural behaviours, and the size of the social group in various cetacean species, researchers found that species with larger brains tend to have a broader repertoire of social behaviours, live in medium-sized groups of 5 to 20 individuals, and be united by strong social bonds. The smallest brains were found in solitary species or those that live in small groups.<\/p>\n

In humans, the brain is believed to have grown larger (a process known as encephalization) as our social skills (e.g. language, pursuit of common goals, teaching, consensus-based decision-making and empathy) developed. These skills favour cooperative social interactions and have allowed humans to colonize the majority of terrestrial ecosystems.<\/p>\n","protected":false},"excerpt":{"rendered":"
