Well, Ill be a monkeys uncle! Although it was shocking initially, we now accept that other apes share 99% of our genes. However, what even makes an ape, and are people apes too? To tell the story of whether or not people are apes, we need to venture on a linguistic journey.

Some monkeys even have the word “ape” in their name, such as the Barbary ape. In everyday usage, the terms monkey and ape are often used interchangeably. However, in contemporary biology and primatology, most researchers refer to apes that are not human as “non-human” apes.
Historically, the word “ape” has actually been utilized to distinguish in between people and, well, other primates. After the word “monkey” was presented into the English language, it was either used as a synonym for “ape” (according to a 1910 Encyclopaedia Britannica entry) or to particularly name primates without tails.
The significance of the word “ape” has actually changed over time and has been used to describe various things. The reason for this change in time is the quantity of understanding that we have of other primates. Furthermore, researchers use the word differently than you or I would in daily use.
The Science of Taxonomy
Within the Eukarya domain, organisms are further categorized into kingdoms, phyla, classes, orders, families, genera, and types. People, for example, belong to the animal kingdom, the chordate phylum, the mammal class, the primate order, the hominid family, and the Homo genus. Our types name is Homo sapiens.
Prior to diving into the specifics of human and ape biology, its essential to understand how scientists categorize living things. The science of taxonomy involves organizing organisms based upon shared physical and genetic characteristics. At the a lot of standard level, all living things can be organized into one of three domains: Archaea, Bacteria, and Eukarya. The latter domain consists of all plants, animals, fungis, and other organisms with a nucleus in their cells.
The Ape Family
Like people, apes are members of the primate order. Strepsirrhines consist of lemurs and lorises, while haplorhines consist of tarsiers, human beings, apes, and monkeys.
Apes themselves are divided into two households: Hylobatidae and Hominidae. Hylobatidae, likewise called the lesser apes, consists of gibbons and siamangs. Hominidae, or the primates, consists of orangutans, gorillas, human beings, chimpanzees, and bonobos.
A classification that has actually remained fluid throughout history

Monkeys were thought about less sophisticated than apes and were identified this method. In the 1940s, some scientists, such as Frederic Wood Jones, challenged this idea that complexity simply increased from lemurs to monkeys to apes to human beings.
Apes and the tree of life
A third shared quality is our big brains. While human beings have the biggest brains relative to body size, other apes also have reasonably big brains compared to other mammals. In truth, chimpanzees have actually been shown to have cognitive abilities that are similar to those of young human kids.
In the previous 50 years, scientists discovered more about the relationships in between the species with molecular studies. They discovered that gibbons form a different group, however that humans are very closely related to chimpanzees and gorillas. When human beings were thought about really different, the term “ape” was utilized to describe this group of other primates that we were various from. Now that we know that were really similar and in fact part of the exact same grouping, this old meaning does not work so well. If you state “Oh, simply chimps, orangutans, gorillas, and gibbons are apes” then you are creating a synthetic group, since human beings should be part of this group by their relatedness.

When scientists started creating the tree of life, humans and “apes” were completely separate groups. Chimpanzees, orangutans, gibbons, and gorillas were considered to be in one group, and human beings in a separate group.
While these resemblances may appear little, they represent a considerable link in between humans and other apes. The genetic similarities between humans and other primates are frustrating.
Another shared quality is our opposable thumbs. Human beings, together with other apes, have thumbs that can move independently of the other fingers, allowing us to comprehend and control things with excellent precision.
Undoubtedly, this is the most common in daily use for laypeople too. The Merriam-Webster dictionary defines an ape as “any of various large tailless semi-erect primates of Africa and southeastern Asia (such as the chimpanzee, gibbon, orangutan, or gorilla)”.

What physical traits do people share with other apes that make us part of the same family? Possibly the most apparent is our absence of a tail. Unlike numerous other mammals, including human beings, apes and monkeys do not have a tail extending from the end of their spine.
Its not simply physical qualities that link humans to other apes. Human beings share around 98.8% of our DNA with chimpanzees and 96% with gorillas.
Many viewpoints
There is still a terrific offer of difference, even in the scientific neighborhood, about whether people are thought about apes. Lots of, as formerly mentioned, consider this whole Hominoid group as apes. Other researchers still use the historical meaning, to describe non-human primates.
Some scientists argue that we are not apes however ex-apes due to the fact that we are essentially various from other apes. These differences are due to the way we interact and other things that are not visible simply by taking a look at DNA. In this case, the word “ape” need to imply something various than Hominoid.
Physical Similarities
The yellow group (monophyletic) is the most useful. The blue group (paraphyletic) is the kind of group that “apes” would be if human beings werent consisted of– not so helpful and total. Image credits: Petter Bøckman, modified by Peter Brown.
Genetic Similarities
Biologists do not like groups that only include a few of their members because they arent extremely informative or representative. They rather use monophyletic groups that include all of the descendants of a typical forefather. “Ape” now becomes another word for Hominoid, the all-encompassing group that includes human beings, gorillas, gibbons, orangutans, and chimps. Within this group, people are included with the rest of the primates. The term “great apes” specifically consists of human beings too. Researchers distinguish in between humans by calling them Hominin and others as “non-human apes”.

If you state “Oh, simply chimps, orangutans, gorillas, and gibbons are apes” then you are producing an artificial group, because humans need to be part of this group by their relatedness.
What even makes an ape, and are humans apes too? Some monkeys even have the word “ape” in their name, such as the Barbary ape. In contemporary biology and primatology, a lot of scientists refer to apes that are not human as “non-human” apes.
There isnt an uncomplicated response to the question of whether humans are apes or not. The most typical consensus is that non-human primates are thought about apes, but many biologists are significantly designating people as part of this simian clade.
The blue group (paraphyletic) is the type of group that “apes” would be if human beings werent included– not so helpful and complete.
