Humpback whales have brain cells also found in humans

...-formation, cooperation, cultural transmission and tool usage," the authors state. "It is thus likely that some of these abilities are related to comparable histologic complexity in brain organization in cetaceans and in hominids." The authors conclude: "Cetacean and primate brains may be considered as...

Singing for survival

..."Vocal behaviour appears to function as a powerful tool to deal with immense sexual competition under which these primates operate, and it may not be surprising that they have evolved unusually complex vocal skills to deal with these social challenges. "Not unlike humans, gibbons assemble a finite numbe...

Circadian gene helps the brain predict mealtime

...udy point out that the work they report provides a tool for investigating the brain's cerebral clockwork responsible for predicting mealtime--with this tool in hand, it will be possible to anatomically localize areas of the brain that are involved in food a...
