Where did we come from? A question that will always be asked by every human on this planet. Some say that we are of God’s creation and some say that we have gone through a long process called evolution and that humans and apes share a single common ancestor. Here I am going to compare and contrast between two of my favorite types of animals: The Lemur and the Gibbon. What is a Lemur? Ask someone that question and you’ll be surprised how silly the answer may be. From being a fruit to a body part, it is sad how the general public does not know that the Lemur one of our oldest primates, an order which includes monkeys, apes, and us humans. There are about 32 different types of lemurs on our planet today. They originated from Madagascar, a large island that sits just off the coast of Southeast Africa. To fully grasp the differences between lemurs and primates you have to take things step by step. Primates can be broken down into two suborders: Anthropoids and Prosimians. We with the monkeys and apes are Anthropoids. Lemurs, Lorises, and Tarsiers are Prosimians. Unlike all primates, Prosimians have most noses like dogs and rely on their sense of smell to find the differences between individuals in their groups. Like other primates, Lemurs groom themselves and each other. They unfortunately can’t use their fingers like you and I so they have teeth that act as a comb. Their diet consists of mostly fruits and leaves. They are about 15 inches high and t...
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
"Where did man come from? Where did time begin? Who, or what, created all things?" These are questions that mankind has sought to answer from the beginning of existence as it is known today. Many stories and fables have been told and passed down from generation to generation, yet two have survived the test of time and criticism.
: 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.

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.
In essence, the difference is simple, human primates have language while non-human primates do not. Even though non-human primates do not have
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.
Apes, like humans, are catarrhines and part of the superfamily hominoidea. Apes started to appear in the Miocene about 20 million years ago(lecture notes, week 10), under this category there are many primates that are distinguished as apes, such as, orangutans, gibbons, chimpanzees, and gorillas. These particular primates are from the old world and are native to Africa and Asia. Apes can be distinguished by the foramen magnum towards the back of the skull, having no tail, and having a hook nose (Larsen 2013, p. 150). Another characteristic of apes is that they have large brains for their body size, this is important because it shows they have a higher intelligence than other animals, and this can be connected to the relationship shared with humans.
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.
Around five to seven million years ago in Africa, a man/ape primate ventured about in the wooded areas. (Morgan, 1982) “My thesis is that a branch of this primitive ape-stock was forced by competition from life in the trees to feed on the sea-shores and to hunt for food, shellfish, sea-urchins etc.”, quoted from Alister Hardy. For the need of food, shelter, space, and resources, the hominid relocated from its traditional environment of the tree, toward water. As evident today, many species of monkeys and apes seek these resources in trees. According to Elaine Morgan, the man/ape primates that stayed and continued to survive in the wooded environment millions of years ago, are the direct ancestors of today’s monkey and ape primates, while the ones that chose to move to the water are the direct ancestors of today’s humans. As proposed by AAT, this is the point along the evolutionary line in which humans and ape primates split.
The idea that humans could possibly have evolved from apes was thought impossible until about 150 years. Charles Darwin, an English naturalist and geologist, best known for his contribution to evolutionary theory, stated “humans evolved from an apelike ancestor” (1). Still after Darwin’s theories, many people still doubted the chances of this being true. Just in the past decade have scientists reached a general agreement about the evolutionary relationships between humans and apes. DNA evidence indicates that chimps and bonobos are more closely related to humans than they are to gorillas! Technically humans are a kind of great ape, and that is why throughout the article Smuts will refer to apes as forest apes.

“The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.
Chimpanzees are part of the non-human primate group. Though we share a common ancestor, evolution has pushed us in different directions. However this common ancestor causes humans to be curious about these creatures. As discussed in Jane Goodall’s video Among the Wild Chimpanzees we were once considered to be human because of our use of tools but once we observed these non-human primates using tools, this perception was changed forever. The question now at hand is if having the chimpanzees that we study in captivity makes a difference between studying wild chimps. These interesting creatures can be found naturally in the rainforests of Africa.
Creationists believe that humans were always humans. Humans are classified in the mammalian family Primates. In this arrangement, humans, along with our extinct close ancestors, and our nearest living relatives, the African apes, are sometimes placed together in the family Hominidae because of genetic similarities. Two-leg walking seems to be one of the earliest of the major hominine characteristics to have evolved. In the course of human evolution the size of the brain has been more than tripled.
