She adds, "They're doing things that nobody thought that they could, and they're learning with this high fidelity." "Imagine what the poke group looks like, and then you've got your two cultures," says Horner, watching Steward. It has been six months since Steward has seen the Pan-pipes, and he's sticking with lifting. Horner also taught a high-ranking female in another group of Yerkes chimps to use the poke technique to push treats from the Pan-pipes. Andrews, and Frans de Waal, a primatologist at Yerkes. They learned the lift after Horner taught Ericka the behavior, in collaboration with Andrew Whiten, a psychologist at Scotland's University of St. Most of the subordinate chimps surrounding him are expert lifters as well. Steward learned the secret of the Pan-pipes from one of the very chimps huddled around him: alpha-female Ericka. His human caretakers didn't teach him this relatively complex behavior, nor did he figure out the lift on his own. What is remarkable, however, is how Steward obtained this skill. So, the fact that Steward can operate the Pan-pipes using a simple tool isn't groundbreaking. Tool use is well documented in both wild and captive chimpanzees. His entourage looks on, rapt but patient. A steady rhythm develops: the click of Horner introducing an M&M into the back of the Pan-pipes, the clunk of Steward lifting the internal gate, and the tinkle of the treat rolling down the shoot into his hand. For these reasons, there is a consensus that great apes are some of the most intelligent animals on the planet.Victoria Horner, a postdoc at Yerkes' Living Links Center, keeps the Pan-pipes stocked with fresh M&Ms. There are academics who believe that chimpanzees actually develop their own cultures – unique tendencies and behaviors that are learned or imitated within certain chimpanzee groups that are in contrast to other groups. However, it’s more for their behaviour that great apes are differentiated from other apes – specifically their ability to use tools and language, and their complex social groups and lives. Physically great apes have some common features, such as an almost naked face, no cheek pouches, and opposable thumbs that are shorter than their other fingers. The term ‘great ape’ refers to a sub-category of apes known as Hominidae, made up of orangutans, chimpanzees, bonobos, orangutans, gorillas, and us – humans (basically all apes except the gibbon family, members of which are known as lesser apes). There are no apes or monkeys (or any primates at all) in Australasia. This last difference between monkeys and apes might come in useful if you’re in the Americas, where if you see a primate in the wild it definitely won’t be an ape! Apes are found only in Africa and Asia, whilst monkeys live in Central and South America as well as Europe, Africa, and Asia. At the top of the chart in white are primate species that are neither apes nor monkeys, namely galagos, lorises, and lemurs: This taxonomy of primates should help you understand where apes (green), Old World monkeys (yellow), and New World monkeys (orange) – sit in the overall primate family. Anthropoids vary considerably in size, geographical range, and behavior, but they are similar in that they all have flat faces, small ears, and relatively large, complex brains. (Read more about Old World African monkeys.)Īpes, Old World monkeys, and New World monkeys all diverged from each other many millions of years ago, and are all part of a sub-family (suborder) of primates known as Anthropoids. These two groups themselves have many divergences, with significant differences between the two groups include opposable thumbs, sitting pads, nose and septum shape, and prehensile tails. The term ‘monkey’ is generally accepted to refer to two groups of primates – New World monkeys and Old World monkeys. A primate is an animal belonging to the biological order ‘ Primates’, a group that contains all species of lemurs, monkeys, and apes worldwide. Ape vs New World monkey vs Old World monkeyīefore looking at the differences between apes and monkeys, it’s important to know that apes and monkeys are both types of primates. So, how can you tell which animals are monkeys, and which are apes… and what exactly are the differences between monkeys and apes? Let’s start with a little evolutionary biology. In some cases, monkeys and apes can live side by side, or look similar, but after a little research, it’s obvious that there are a number of significant differences between the two groups. Can you tell the difference between apes and monkeys? For much of history, there was no ape vs monkey debate, and the terms were used interchangeably, even though apes and monkeys are actually very different animals. ![]()
