Ape features
distinctive molar teeth in the lower jaw which have a ‘Y5’ pattern (five cusps or raised bumps arranged in a Y-shape) a shoulder and arm structure that enables the arms to freely rotate around the shoulder.
How many molars do primates have?
4.3, meaning one side of the mandible has 3 incisors, 1 canine, 4 premolars, and 3 molars. Because primates have more flexible diets and shorter faces, they have fewer and more generalized teeth.
Do Old World monkeys have Y 5 molars?
More specifically, the apes can be distinguished from Old World monkeys by the number of cusps on their molars: apes have five, the “Y-5” molar pattern, while Old World monkeys have only four in a “bilophodont” pattern.
How many molars does a chimpanzee have?
All in all, chimpanzees are expected to grow a total of 32 teeth inside their mouths, which include 8 incisors, 4 canines, 8 premolars in the middle of the jaws, and 12 molars at the rear portion of the mouth. This dentition pattern is likely shared by humans as well.
Are baboons hominoids?
Baboons are among the largest non-hominoid primates and have existed for at least two million years.
Do Cercopithecoids have Bilophodont molars?
Although cercopithecoids are highly variable in habitat use, social behavior, and diet, a signature dental feature unites all of its extant members: bilophodonty (bi: two, loph: crest, dont: tooth), or the presence of two cross-lophs on the molars.
What are Bilophodont molars?
The bilophodont tooth pattern is found in cercopithecoid monkeys in the three upper molars as well as the first and second lower molars. In the mandibular molar, an elongated heel at the back of the tooth carrying a fifth cusp, the hypoconulid is added on to the typical bilophodont tooth.
Which of the following are hominoids?
Apes, also referred to as hominoids, include chimpanzees, gorillas, orangutans, and gibbons.
Which primates have a Rhinarium?
Primates are phylogenetically divided into those with a rhinarium, the Strepsirrhini (the prosimians: the lorises, and the lemurs); and those without a rhinarium, the Haplorhini, (the Simians: monkeys, apes, and humans).
Do chimpanzees have Y 5 molars?
In addition, the lower molar teeth of apes and humans have five cusps, or raised points, on their grinding surfaces. This is known as a Y-5 pattern because the area between the cusps roughly is in the shape of the letter Y. Monkeys only have four cusps on their lower molars.
How many teeth do primates have?
4 . 3 = 44 teeth (the numbers being the numbers respectively of pairs of incisors, canines, premolars, and molars in the upper and lower jaws). No living primate has retained more than two incisors in the upper jaw. The incisors are subject to considerable variation in strepsirrhines.
How many teeth do spider monkeys have?
They have 32 teeth in total; eight incisors, four canines, eight premolars, and 12 molars. In addition to their canines, their lower first premolar is large and bladelike, with a sharp crown.
Which type of primate has a toothcomb?
The toothcomb occurs in lemuriform primates (which includes lemurs and lorisoids), treeshrews, colugos, hyraxes, and some African antelopes. The structures evolved independently in different types of mammals through convergent evolution and varies both in dental composition and structure.
How many teeth do gorillas have?
Gorillas have 32 teeth, just like humans! Unfortunately for them, only humans have a Tooth Fairy. Just like us, gorillas have molars and premolars for grinding and chewing their food.
How many teeth are in a chimps maxilla?
There are sixteen teeth found in a Pan troglodyte’s maxilla. As an Old World primate species, their dental formula is 2.1.2.3, meaning two incisors,… See full answer below.
What primate has Y-5 molars?
Within this grouping, the two families Hylobatidae and Hominidae can be distinguished from Old World monkeys by the number of cusps on their molars; hominoids have five in the “Y-5” molar pattern, whereas Old World monkeys have only four in a bilophodont pattern.
What is the difference between Bilophodont molars and Y-5 molars?
A Y-5 molar pattern is when the tooth is separated in to an amount of different pieces that make up the complete tooth. Bilophodont molar pattern is when the molar is in distinct 2 sections.
What are the 5 groups of primates?
Orangutan, gorilla, chimpanzee, bonobo and human. These are the five great primates, which are so defined because they do not have tails and are a little bit ahead of their cousins monkeys on the evolution scale.
What characteristics differentiate Cercopithecoids and hominoids?
Finally the difference with Cercopithecoids and Hominoids Cercopithecoids have a narrow nose & palate & smaller brains rel. to body size than Hominoids. Cercopithecoids molars have two cusps but Hominoids have several cusps. Cercopithecoids have tails often long, while Hominoids have no tails.

What is the difference between Strepsirhini and Haplorhini?
The main difference between Strepsirrhini and Haplorhini is that Strepsirrhini contains lower primates, mainly lemuriform primates, whereas Haplorhini contains higher primates including New World monkeys, Old World monkeys, and apes.
What is the difference between Strepsirrhines and Haplorhines?
Strepsirhines have longer snouts, smaller brains and a more highly developed sense of smell than haplorhines. Haplorhines have shorter faces, larger brains and a more highly developed sense of vision than Strepsirhines; their eyes face more forward than the eyes of strepsirhines.
Do Japanese macaques have ischial callosities?
Japanese macaques have cheek pouches for food storage and exhibit sexual dimorphism (males and females look different). Mature males are larger and have pronounced canine teeth. They also have brightly colored ischial callosities (buttocks pads).
Which trait differentiates hominoids from primates?
Some characteristics that have distinguished hominins from other primates, living and extinct, are their erect posture, bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use and, in some cases, communication through language.
What are the 5 stages of human evolution?
- Dryopithecus.

Do gorillas have rhinarium?
Answer and Explanation: No, great apes do not have a rhinarium, which is the skin surface around the external opening of the nostrils in several species of mammals.
Are galagos insectivores?
Galagos have large ears with great mobility that are continuously moving. As insectivores, they rely on sound to localize their prey (Charles-Dominique, 1977).
Which primates are Brachiators?
Brachiators by design are gibbons and spider monkeys, which have odd upper arm muscles and reduced thumbs. Female orang-utans are also brachiators – they are just less acrobatic about it than gibbons.
What is the difference between hominoids and hominins?
Hominids | Hominoids |

Homo sapiens have a larger brain than hominoids. | Hominoids’ brains are smaller than hominids’. |
Which animals have a rhinarium?
Examples of mammals that have rhinarium include streptorrhines (i.e. lemurs, lorises, pottos, and galagos), cats, dogs, elephants, and walruses.
Is an orangutan a monkey?
Orangutans are great apes, as opposed to monkeys, and are closely related to humans, having 97% of DNA in common. Orangutans are extremely patient and intelligent mammals.
What is the cp3 complex?
C/P3 honing complex: Refers to the arrangement of the upper canine and lower third premolar that allows the back edge of the upper canine to be sharpened or honed against the front edge of the lower premolar.
What do the Catarrhines include?
Catarrhines include gibbons, orangutans, gorillas, chimpanzees, and humans. Two superfamilies that make up the parvorder Catarrhini are Cercopithecoidea (Old World monkeys) and Hominoidea (apes).
Do strepsirrhines have tooth combs?
Among the living primates it is the strepsirhines who possess a tooth comb, and these primates are also the ones which use it as a comb for the explicit purpose of grooming.
What type of teeth do chimpanzees have?
Primates have four kinds of teeth in their mouths: incisors, canines, premolars, and molars.
Do primates have canine teeth?
Abstract. Anthropoid primates are well known for their highly sexually dimorphic canine teeth, with males possessing canines that are up to 400% taller than those of females.

3.2 (consisting of 2 incisors, 1 canine, 3 premolars, and 2 or 3 molars).
How many teeth do Chimps have?
Chimpanzees have a total of 32 teeth in their mouth. This is the common dental formula for all apes as well as all Old World monkeys.
How many teeth do squirrel monkeys have?
They have 36 teeth, and their teeth are sexually dimorphic in that males have large upper canines. Squirrel monkesy possess nails instead of claws, and they have been called ‘small, nervous primates’.
Do all the monkeys have 32 teeth?
Most monkeys have the same number of teeth as humans do: 32, with 16 on top and 16 on bottom. However, the type of teeth depend on a monkey’s…
What are the 7 species of spider monkeys?
Geoffroy’s spider monkey (Ateles geoffroyi): Endangered. Guiana spider monkey (Ateles paniscus): Vulnerable. Brown spider monkey (Ateles hybridus): Critically endangered. White-bellied spider monkey (Ateles belzebuth): Endangered.
Why are gorilla teeth black?
As a result, their diet is high in tannins. In fact, these are the same compounds that make your daily cups of tea and coffee bitter. Just like drinking coffee will stain your teeth over time, the mountain gorillas’ teeth are stained to almost black by their high tannin diet.
What type of molars are possessed by gorillas?
Gorilla, for example, possesses large molars with moderately thick enamel (in absolute terms), resulting in high crown strength despite an RET that is among the smallest for extant hominoids (table 1).
Do gorillas have claws?
Hands and Feet
Gorillas are able to manipulate objects with their feet as well as their hands because of their opposable big toe. Primates have fingernails and toenails rather than claws. They are used for opening, scraping, cleaning, and scratching.
What kind of molars do apes have?
The premolars (or bicuspids) and molars, with their multiple cusps, are used to grind and smash food. In platyrrhine species, there are 3 premolars and 2 or 3 molars. This results in a dental formula of 2.1. 3.2 or 2.1.
Do humans have large molars?
Compared to modern humans, many hominins had toothier mouths. The “Nutcracker,” (aka Paranthropus boisei), a hominin that lived 2.3 million years ago, had the largest molars and thickest enamel of any hominin. Homo erectus, which lived all over the world 1.5 million years ago, had larger canines than modern humans.
How many teeth are found in each species maxilla?
Four or five teeth are present on each maxilla. The maxillae are unusual in that they lie horizontally against the roof of the mouth with their transversely oriented tooth rows directed posteriorly.
What are Bilophodont molars?
The bilophodont tooth pattern is found in cercopithecoid monkeys in the three upper molars as well as the first and second lower molars. In the mandibular molar, an elongated heel at the back of the tooth carrying a fifth cusp, the hypoconulid is added on to the typical bilophodont tooth.

Apes (Hominoidea) are a group of primates that includes 22 species. Apes, also referred to as hominoids, include chimpanzees, gorillas, orangutans, and gibbons.
How many molars do primates have?
4.3, meaning one side of the mandible has 3 incisors, 1 canine, 4 premolars, and 3 molars. Because primates have more flexible diets and shorter faces, they have fewer and more generalized teeth.
Do hominoids have tails?
Living hominoids are united by features related to habitual orthogrady and below-branch behaviors: broad torsos with widely-spaced shoulder joints, stiff backs, long forelimbs, mobile limb joints, strong grasping ability, and the absence of a tail (Huxley, 1863; Harrison, 1987 & 1991; Shoshani et al., 1996).
Do primates have rhinarium?
Primates are phylogenetically divided into those with a rhinarium, the Strepsirrhini (the prosimians: the lorises, and the lemurs); and those without a rhinarium, the Haplorhini, (the Simians: monkeys, apes, and humans).
Do Old World monkeys have Bilophodont molars?
It is suggested that the development of bilophodont molars might be an adaptation by Old World monkeys to seed predation. Given their large size relative to other arboreal frugivores, seed predation could provide a dietary niche for Old World monkeys.
