Are lemurs considered to be a primate? What is a primate and what does a primate consist of? A primate is known for having hands and feet that are very similar to the look of their hands. They also are known for their forward-facing eyes. Primates are not just lemurs. Primates also include prosimians, monkeys, apes, and even humans. The first primate to be developed was a lemur. The word lemur in latin means ghost because lemurs are a nocturnal animal. A Lemur is also an arboreal primate, which meaning that they live in all kinds of trees. All breeds of lemurs have a slightly long pointed snout and typically have a long tail. Lemurs have been around for nearly over 2,000 years (Garbutt 10). This was when they first stepped foot on the islands. Although there are many breeds of lemurs and more still being discovered, they are mostly all found and living in one particular island, and have different characteristics and behaviors than some other animals, they are still considered to be a primate because of their wonderful amazing features.
Lemurs are known as prosimians. The meaning of prosimians is that they are considered to be a pre-primate (Darling 8). In other words, they were one of the first primates to be discovered and that they came before monkeys. Prosimians also means that lemurs are considered to have characteristics that are more primitive than those of monkeys and apes. Lemurs can be characterized as one of the most endangered animals. They are endangered because humans enter there Madagascar rainforest island and started to cut and burn it down. They did this so that they could use the land for farming. Humans also killed and ate the lemurs. With Madagascar being cut down the lemurs were losing th...

...e during the year. Researchers have found that female coquerel dwarf lemurs mostly starting matting during the month of October. Their development and pregnancy last about 90 days. Like all mammals, lemurs feed off their mothers for milk. And they can live up until the ages between 20 and 25 (Garbutt 52).
From the way lemurs look to the way lemurs act they are indeed primates. They all have many different characteristics as other non-human and human primates. Lemurs behaviors also help demonstrate how they live and survive as a primate. And even though lemurs are known to be endangered species, they are magnificent animals and should not be hunted by people. Their island should be protected to save them and other animals. The way they leap, live in groups, find and hunt food, to the way they nurture their new born makes these primate lemurs amazing mammals.
: They are important from a biological anthropology perspective because they only had one similar characteristic with primates which was their teeth. It was a transitional specimen. The Dryomomys also give us a lot of information about how it all started in the “Tree of Life”. Monkeys, apes, lemurs, us, and all other primates are related to the Dryomomys. The Dryomomys is the primitive primate and the closest to the base of the tree.
Dr. Goodall is a well-known British primatologist who has discovered a substantial amount about primates in her many years of research. She has written numerous books, including one that we will be going into depth about called, “Through a Window.” Her book contains personal experiences, research findings, and even pictures to help the readers visualize her scientific breaking moments from her thirty years with the chimpanzees of Gombe. She states that there is are minor differences, and several similarities between humans and the chimpanzees. We will discuss these differences and similarities through their social behavior, intellectual ability, and emotions. To conclude, examine Goodall’s research to adopt what her findings can tell us about our early ancestors, and whether or not her study coincided to the steps of scientific methodology.
I observed chimpanzees in the Kimberly-Clark Chimpanzee Forest exhibit at the Dallas zoo. These African apes, like humans, are hominoids and fall into the larger category of catarrhines. Their scientific classification is Pan troglodytes. There were about ten chimpanzees in that habitat. Most of them were grown adults, except two children. They were robust and had black fur. The average weight of the chimps was listed on a display to be about 115 pounds.
Chimpanzees make tools and use them to procure foods and for social exhibitions; they have refined hunting tactics requiring collaboration, influence and rank; they are status cognizant, calculating and capable of trickery; they can learn to use symbols and understand facets of human language including some interpersonal composition, concepts of number and numerical sequence and they are proficient in spontaneous preparation for a future state or event.
I visited the Sacramento Zoo during the afternoon of April 21, 2017. The weather was wonderful, sunny, warm, and there was a slight breeze. It got a bit more breezy the longer I was there. Visiting the zoo to observe primates allowed me to become a little more aware of how primatologists study primates. Even though I’ve been to many different zoos several different times, I never realized how many primates were associated with the zoos, as well as the variety of primates in the zoos. The Sacramento Zoo has eight different primates, all in different classifications, superfamilies, or subfamilies. While observing the Chimpanzees, White-Handed Gibbon, Mongoose Lemur, White-Faced Saki, and the Wolf’s Guenon I could see the differences
Their offspring is one. The lifespan of the ring-tailed lemur is 20 years. They have a
Primates, any placental mammal of the order Primates, normally having flexible hands and feet and, in the higher apes, a highly developed brain (“Primate”, 2016), have been one of the most popular animals and prominent attractions in zoos.
All primates have the same sensation and are capable of receiving excessive amounts of information. All senses, sight, smell, taste, hearing, and touch are essential to the development, survival, and overall well-being of living primates. It is fascinating how non-human primates, without language, can communicate in the same ways as human primates, with language. Non-human primates and human primates are highly developed mammals that possess many of the same communicative characteristics, but still differ greatly. Non-human primates fit into the category of not having language, but being able to communicate.
There has been an age long debate to whether or not primates have culture. This is based on the idea that primates may have certain behaviors that our taught rather than already being programmed in their minds biologically. Some would argue that a certain action that a primate does wouldn’t necessarily be something that primate was born knowing; but others would argue that it was something that was something they knew in their subconscious mind. Notable arguments that would be in favor of culture in primates would include their use of tools, how a primate eats, and how they interact; arguments against the theory of culture in primates would proclaim that a primate’s habits are determined biologically and not affected by outside sources.
Our earliest ancestors are primates. They are our closest relatives which is why we can see our behavior’s and practices in them. If we observe them we can get a better understanding of them and us, human beings. But unfortunately we all don’t get the chance to see a Primate right in our backdoor. So the best thing I could do for my observation was to visit them at the zoo.
Throughout situations and research conducted by not only Robert Sapolsky or Jane Goodman, but from many other credited sources, we can blatantly see the, if not identical, similarities between the two species of humans and baboons. The most apparent likewise characteristics of this can be read and documented in Professor Sapolsky’s book, A Primate’s Memoirs. Sapolsky, who spent hundreds if not thousands, of hours studying these Savanna Baboons, sheds a vast insight into ideas of social dominance, mating strategies, instinctual prowess, community settings, hygiene, and reform of an entire generation; many of which can be unknowingly seen directly in the common occurrence of a humans daily life.
It has been believed that culture is unique to humans and no other groups of animals have culture, but recent evidence refutes this ideology. Before getting into the meat of the argument, it is important to first address the issues regarding the ambiguity of the term, “culture.” What is culture? Many scientists may argue that culture is the way of life for a group of individuals, this definition includes the values, beliefs and traditions of the group (Sapolsky, 2006). Other scientists may argue that culture is the transmission of habits and information by social means (Sapolsky, 2006). Despite the different specifics of what culture is, almost all scientists would agree that culture is transmitted socially through social learning that promotes the transfer of information between members in a group (Boesch and Tomasello, 1998). Based on these notions of culture, it can be justifiably stated that primates have culture. Primates exhibit food preparation techniques, use of tools, communication skills, and most importantly, behaviors of social learning. An exemplar of primates’ capabilities for culture is Koko, the lowland gorilla. Koko, in captivity, was able to learn American sign language, demonstrate self-awareness and the ability to deceive.
Non human primates’ social organization can provide useful information how human social evolution occurs. We will go over main points of how similar and different non human primates such as chimpanzees, orangutans, and gorillas’ society are compared to ours, humans.
The first group of primates was the Ardipithecus group. They were the earliest humans closely related to other primates. The Ardipithecus group evolved in Africa and took the first step upright on two feet. Sahelanthropus tchadensis was the first human species to ever walk the earth. They were the building block of more complex species to come. There were many species that started the human race such as the Orrorin tugenensis. This species was nicknamed the Millenium Man and live 5.8-6.2 million years a...
Other than big cats, primates from lemurs, monkeys, chimpanzees to baboons are one of a variety of primate species that are also kept as exotic pets and can be very challenging to handle. You can say that they are cute and "child-like", but they are not a substitute for human babies. Sure their owners treat them like babies...
