1) How are Plesiadapiforms spoken about in the First Primates video?
: The Plesiadapiforms are tiny mouse like creatures that lived during the 10 million period between the extinction of dinosaurs and appearance of humans. This could be our primate ancient ancestor. This primate has around more than 120 different species of its kind.
2) What does recovered finger nail tell the paleontologist in the First Primates video?
: Finding a fingernail instead of claws was a huge surprise and it is considered a huge hallmark for our primate history. The paleontologist was actually expecting a huge claw at first and getting a small nail was a shock for him. Nails also make it easier for primates to gather food rather than claws which gives it a similar characteristic to us.

Their work together not only made sense, but they were able to build and add more into the Tree of Life among primates
5) What are Dryomomys and why are their important from a biological anthropology perspective? What do these fossils tell scientists about early primate evolution? : 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.
6) What type of coevolution is described in the First Primates video? : Primates didn’t just appear among Earth, but they evolved. The coevolution has to do with flowers and fruits. Fruits were evolving to get tastier for primates to eat and as primates ate them they spread them around as well. As they ate these new evolved fruits and flowers this invited changes onto their bodies as
A study performed by Martin Hausler and Peter Schmid of the University of Zurich, Switzerland, appeared in the October 1995 issue of Journal of Human Evolution, igniting controversy over the 1974 Australopithecus discoveries in Hadar, Ethiopia. The most famous of the Hadar specimens is the 3-million-year-old skeleton, “Lucy,” who was recovered by paleoanthropologist, Donald Johanson. In his article, Shreeve presents the methods and findings of Hausler and Schmid’s study as well as some counter arguments from other scientists in the field.
Tool-use is regularly reported in chimpanzees. They use many different tools to carry out many different tasks. They use sticks to fish for insects, stones and wood to crack open nuts, leaves to soak up liquid, and branches used as weapons to dominate opponents and frighten off predators. In making tools, they may use a variety of different materials to make the same kind of tool. For example, they use sticks, twigs, bark, and vines to fish for termites. They also may use the same material for different purposes. A leaf could be used as a termite probe, a napkin, or a sponge.
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.
The evolution of man is constantly in question. While we are reasonably sure that modern humans and primates are both related to the same common ancestor, there is constant debate over what initially caused the two species to split into early hominids and apes. According to some, our longest and most popular theory on the division of man and ape is profoundly wrong. However, those same individuals usually offer an equally controversial theory as a substitute, one that is almost impossible to scientifically test or prove. Both the Savanna Theory and the Aquatic Ape Theory offer solutions to how and why humans evolved into bipedal toolmakers. But with enough questioning, each loses its accountability to rhetorical science.
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.
One example is the unique shape of a koala’s hands.The front paw of a koala looks fairly similar to a human’s hand. However, it has two thumbs and three fingers. Their hind paws are different from the front paws. The second and third digits of their hind paws are fused together and they have one thumb. They have sharp claws on both paws that help them have a good grip on trees. The rough skin on their palms is another factor that assists them when climbing the tree. By taking a closer look at the hands of koalas, one can see another piece of evidence for evolution. The fingerprints of koalas are very similar to those of humans. This is an example of convergent evolution. Scientists believe that both human and koalas have fingerprints because they both need the ability to grasp on objects. Fingerprints give control when grasping something. Although ancestors of koalas and human have branched apart about 70 million years ago, the two species have developed fingerprints for a similar
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.
The species A. afarensis is one of the better known australopithecines, with regards to the number of samples attributed to the species. From speculations about their close relatives, the gorilla and chimpanzee, A. afarensis’ probable social structure can be presumed. The species was named by Johanson and Taieb in 1973. This discovery of a skeleton lead to a heated debate over the validity of the species. The species eventually was accepted by most researchers as a new species of australopithecine and a likely candidate for a human ancestor.
The early hominins of Africa were similar to other hominins in gross anatomical features, however, there were differences between the early hominins of Africa and other hominins, such as those found in Asia and other parts of the world as discovered in fossil remains. Not only were there some differences in the anatomical structures, there were also evidentiary differences in their culture and environmental factors in their lives, especially as the species evolved. Below, I will compare some of the differences of the early African hominins to other hominins as well as discuss how they might have lived day to day and show how the evidence supports these findings.
In the Video "A Life in the Trees", narrated by David Attenborough many of the characteristics of primates that we have been talking about in class were highlighted. As we talked about in class, primates have two major specializations. Forward facing eyes and hands with opposable thumbs. The video mostly focused on Lemurs, monkeys, and apes. It was clear that, while each one of these groups of primates has those same two specializations, they all use them in slightly different ways, depending on where they evolved.

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...
When talking about evolution, it is not stating that man comes from monkey but rather that man evolves and adapts to his surroundings and environment due to natural selection. In the days of the cavemen, men were hunting while women were caretakers and cooks. Because men were hunters, they became bigger, faster, and stronger in order to have better skills for hunting which was essential for survival. These men passed down these “dominated traits – some flexibility, an instinctive ability to respo...
The increase in brain size may be related to changes in hominine behavior (See figure 3). The third major trend in hominine development is the gradual decrease in the size of the face and teeth. According to the Microsoft Encarta Encyclopedia ’98, the fossil evidence for direct ancestors of modern humans is divided into the category Australopithecus and Homo, and begins about 5 million years ago (See figure 1). Between 7 and 20 million years ago, primitive apelike animals were widely distributed on the African and, later, on the Eurasian continents (See figure 2). Although many fossil bones and teeth have been found, the way of life of these creatures, and their evolutionary relationships to the living apes and humans, remain matters of active discussion among scientists.
Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens. The change of diet of homo-sapiens over time has thought to contribute to the change in jaw structure and overall skull shape.
