Asian elephants have larger brains than their African relatives

African elephants are the largest land animals on earth and significantly larger than their relatives in Asia, from which they are separated by millions of years of evolution. Nevertheless, Asian elephants have a 20 percent heavier brain, as scientists were able to demonstrate. They also showed that elephant brains triple in weight after birth. These results provide potential explanations for behavioral differences between African and Asian elephants as well as for the pachyderms' long youth, during which they gain enormous experience and learn social skills.
