Primates
The two suborders of primates that are recognized today are Strepsirrhini (lemurs and lorises) and Haplorrhini (tarsiers, monkeys, apes, and humans). The taxonomy of primates is an issue that is not resolved and has undergone many revisions over the years. Our Primates category attempts to deal with questions about primate species and subspecies described prior to and since the latest revisions.

Homo erectus. (Human Genetics: Concepts and Applications by Ricki Lewis, 8th Edition, pg 305.)
Culture is defined as knowledge that is passed on from generation to generation. Therefore, non-human primates do have culture. Chimpanzees are a very good example because, just like humans living in different parts of the world, different communities have different ways of doing things. Some Chimp communities use rocks as hammers and anvils to bust open nuts, others use twigs to fish for ants or termites. There is even a community that hunts with spears and cools off in caves! Another good example is the Japanese macaque, the light brown monkeys with pink faces that are often photographed lounging in hot springs. They became famous during the 1950s when one female was observed washing a sweet potato in water. This technique eventually caught on as new innovations are usually adopted by the younger generations and passed on to their own children later--this is an important point that can't be stressed enough. Some years later, one of these macaques started washing their potato in salty sea water. This is a common practice today because they apparently like salt just as much as humans do.
A paper published in 2007, "4,300-Year-old chimpanzee sites and the origins of percussive stone technology," found that Chimpanzees have been using stone tools for at least 4 millennia. Tool use probably goes back much further than this. Man was thought to be the only one capable of using tools until researchers in the 1960s first witnessed Chimps using stone anvils. (Such tool use was actually recorded as far back as the 16th century but forgotten. See "Reports of Chimpanzee Natural History, Including Tool Use, in 16th- and 17th-Century Sierra Leone"). So if both man and Chimps, our closest living genetic cousin, both use tools, our common ancestor who lived around 7 million years ago most likely used tools as well.
A good book for learning the difference between a Chimp's genetically engrained behavior and behavior that is learned (i.e. culture) is Prof. Frans de Waal's The Ape and the Sushi Master (2001).
How would you describe the full-line discount stores?
Extensive width and depth of assortments; average-to-good-quality products, often less fashionable; very competitive prices; average atmosphere and minimal services; significant advertising (e.g., Wal-Mart, Target, and Kmart).
What will happen if black money of india comes OUT?
congress will take a lunch of 12700 swiss francs. and nothing more will happen.
Many scientists think the 24th chromosome fused together and that is why humans have 23.
What are some fact about opposable thumbs?
Opposable thumbs are use to holding on and pick up small objects. The macaques use their opposable thumbs to hold the tool to use it. Without opposable thumbs it could be hard or nearly impossible to use a tool to get food.
How intelligent are chimpanzees?
Chimpanzees are one of the smartest animals in the world. An example would be that chimpanzees can recognize their own reflection in a mirror; while other animals would not. There are several other animals, including all of the great apes, that can pass the "mirror test" as well, but chimps are smart. They seem to possess at least some of the theory of mind where they can act as if they know what another animal can see and how that animal will react to a given action (i.e. maybe they can reason what that other animal is thinking, and therefore that that other animal can think). However, in terms of using human cues, chimps seem to be worse than dogs. They do seem to know how to cooperate to achieve a goal and when they should cooperate.
How many types of primate species are there in the whole world?
Today there are 634 know species & subspecies of primates. I found this answer in my Anthropology the Human Challenge book on page 53 in chapter 3
Describe the major primate groups and explain how they are related phylogenetically?
The Primates order has traditionally been divided into two main groupings: prosimians and simians. Prosimians have characteristics most like those of the earliest primates, and included the lemurs of Madagascar, lorisiforms and tarsiers. Simians included the monkeys and apes. More recently, taxonomists have created the suborder Strepsirrhini, or curly-nosed primates.
How many species of orangutans are there?
I have no idea that's why I loaded the flipping question ! :-}
I don't know but I do know that we are primates and that we cry tears.
Is a orangutan an a ectothermic or endothermic animal?
An orangutan is a mammal like us humans, this means that they are endothermic (warm blooded)
What eats a ring tailed lemur?
This is certainly true in Madagascar, where day-hunting hawks and eagles hunt both sleeping nocturnal and active diurnal lemurs, and fossas and boas hunt day and night. So - meat eating birds, snakes, and other meat eating animals.
because humans hav sex is thet wot ur talking about well its because humans enjoy sex and primates don't only humans and dolphins do the apes just do it naturally and when ur watchin at the zoo thnx another answer from urs truly skyll kid
Why do orangutans make the sound oooh aaah?
Orangutans make the sound "oooh aaah" as a form of communication, often expressing excitement, distress, or to attract attention. This vocalization can serve various purposes, including signaling their presence to other orangutans or indicating their emotional state. The sounds are part of a broader range of vocalizations that these primates use to interact with their environment and each other.
What are the various types of primate locomotion?
Primate locomotion can be categorized into several types: brachiation, which involves swinging from limb to limb using the arms; quadrupedalism, where primates move on all fours, often seen in monkeys; bipedalism, characterized by walking on two legs, primarily observed in humans; and climbing, which includes vertical movement in trees using all four limbs. Additionally, some primates exhibit leaping or saltation, allowing them to cover distances between branches efficiently. Each locomotion type is adapted to their specific habitats and ecological needs.
Why are primates considered the most intelligent mammals?
Mammals are considered the most advanced as they evolved "last" as it were. This meant that the best genetic and phenotype adaptations could be slowly passed on, creating a different species, class and eventually a kingdom.
Mammals posses several aspects that distinguishes them from any other kingdom:
Tooth replacement shared with a few reptiles as well, most mammals have two sets of teeth (though others, such as rabbits have one set, yet these continuously grow) Most mammals also have the enamel that coats the teeth for extra protection.
All mammals can are "warm-blood" which means they can keep homeostasis. Homeostasis is the constant internal temperature despite maybe different external temperatures. For example, if you were to have a mouse and a lizard under a heat lamp, the mouses temperature would be steady as the body is cooling and keeping it at a constant temperature, whilst the lizards internal temperature rises and keeps rising. Lizards and animals that cannot keep homeostasis solely rely on their environment to keep them warm and cool. Because of this, most mammals live in places were reptiles could simply not exist.
Mammals (female) also secrete milk from the mammary gland and nurse there young. This is specialized for mammals- colostrum (first milk) gives young animals a kick-start in life, while milking itself increases offspring and mother bond. Compared to the reptiles or fishes why of breeding, even though lots of offspring (in certain species of fish, millions of eggs) are produce most of them die. This is not as a waste as one would think: these eggs provide vital nutrients for the food chain and ecosystem. However, mammals "look after" there young and protect them: thus prolonging their life.
The largest group of mammals have placentas when they are pregnant, which gives nutrients to the offspring when growing. This is a vital bodily function, and helps with all aspect of the foetus growth. However, many disease can be contracted through the placenta, whilst reptiles do not usually past diseases on through eggs (only through what condition the mothers body is in, i.e.if calcium levels are low, the eggs have soft shells)
Mammals also have the neocortex, which is involved in "high" though processes, such as language, sensory perception, generation of motor commands and conscious thought. In humans the neocortex is relatively big, but you just need to consider the amazement of the human body to understand that.
What are the tissues of rabbit?
Rabbits, like other mammals, have four primary types of tissues: epithelial, connective, muscle, and nervous tissue. Epithelial tissue covers body surfaces and lines cavities, while connective tissue provides support and structure, including blood, bone, and cartilage. Muscle tissue is responsible for movement, consisting of skeletal, smooth, and cardiac muscle. Nervous tissue facilitates communication within the body through neurons and glial cells.
What is the least intelligent primates?
Determining the "least intelligent" primate can be subjective, as intelligence varies widely among species and can be measured in different ways. However, some researchers suggest that lemurs, particularly smaller species like the mouse lemur, may exhibit simpler cognitive abilities compared to larger primates such as chimpanzees or orangutans. Their limited social structures and problem-solving skills can lead to the perception of lower intelligence. Nonetheless, it's essential to recognize that all primates have adapted their behaviors to their specific environmental needs.
