There is no denying that humans have a complex and highly developed system of communication; however, we aren't the only ones. According to this National Geographic article, gorillas have been observed using "baby talk" to communicate with their youngsters. Study leader Eva Marie Luef observed older gorillas using physical contact and repeated gestures more frequently when interacting with infants than they did with other adults. Primate infants learn mostly through observation, while human infants are actively taught how to behave. This discovery of gorillas using "baby talk" may serve as a way to figure out when man's more advanced teaching abilities came about. Gorillas are a highly intelligent and fascinating species. Classic Escapes offers trips to Uganda, as well as Rwanda and Tanzania, where you can get an up-close look at the endangered Mountain gorillas, which are numbered at roughly 700 in the wild today.
