Advantages Of Early Primates

The infamous event of the Piltdown hoax is one that continues to draw speculative attention over a century after the initial announcement of the paleoanthropological findings. Although many scientists, especially those involved in the field of paleoanthropology, would like to forget the incident entirely, the Piltdown man—taxonomically referred to as Eoanthropus dawsoni—is perhaps the greatest hoax in anthropological history. By 1912, British archaeologists and paleontologists were desperate for a significant paleoanthropological finding that would provide the missing link between humans and apes in hominin evolution (Prosser, 2009). The Piltdown man was originally a famous finding that straddled the human-animal boundary, dichotomously

What makes a primate a primate? A primate is defined by its many incredible features. A primate is a mammal that has certain characteristics such as: flexible fingers and toes, opposable thumbs, flatter face than other mammals, eyes that face forward and spaced close together, large and complex cerebrum, and social animals. What makes a primate a primate is its characteristics. Some of the physical features primates are identified by is their teeth, snouts, eyes, ears, arms, legs, fingers, and toes. Human evolution is a big part of humans being primates, and having similar features and characteristics make humans to be considered to be a primate, but both humans and non-humans have differences.

In the article, “Of Primates and Personhood: Will According Rights and ´Dignity´ to Nonhuman Organisms Halt Research?¨, written by Ed Yong, who explains the moral but unclear delma of granting Great Apes rights. Extending from Spain to the U.S., the Great Ape Project (GAP) fights for these basic sets of moral and legal rights for apes. The problem is that apes, although genetically similar to humans are still viewed as simple animals. Which makes the ability to give these non-human animals, human like rights unnecessary as it would to give rights to dogs or rats. The U.S. has also passes the Great Ape Protection Act, which stop any harmful experience to apes. Consequently also stopping any further understanding of underlying biological mechanisms,

In the quest to explain human origins it is necessary to find a species that bridges modern man (Homo sapiens) with the apes. To fill this gap evolutionists have set forth Homo erectus, who lived approximately 400,000 to 1.6 million years ago (Johanson and Shreeve1989). Although the distinctions are somewhat vague, below the neck, Homo sapiens and Homo erectus are practically Identical and Homo erectus was responsible for pioneering the use of standard tools (such as the hand axe), big-game hunting, and the use of fire (Johanson and Shreeve1989).

Primate intelligence correlates to primate cognition which is the study of the intellectual and behavioral skills of primates (Low). In the book Human Evolution and Culture, chapter five "Human Evolution Biological and Culture" states that primates share a lot of common features with mammals but what makes them uniquely different than many other mammals is that primates have a wide range of physical and social traits (86). The social relationships of primates are unique because just like humans, they relationship begin with the mother and other adults that the younger dependable primates. "The dependency of infant primates offers an evolutionary benefit that allows infant primates more time to examine and master the intricate behaviors necessary to survival while enjoying the care and protection of mature adults."(87) Primates have the privilege of having a large brain the size similar to body size to learn the culture and the way of life they live. Larger brains give primates the advantage to obtain an enormous amount of learning and integrate data. Primates have a special gift in areas of their brain that's dedicated to speech and language. (94) Primates have the special ability to communicate with each other as well as with humans and are the "only habitual toolmaking animal" (96). Although primates are more cognitively advanced than many other animals/mammals, researchers and critics still debate on how to define, compare and study intelligence and the growth of

Primates have some features that support them for the arboreal life. First, primates have developed grasping extremities with the divergent hallux and nails instead of claws. These features help them grasping branches better. Second, primates have enhanced vision with the optic convergence, which helps them look straightforward. They also have postorbital bar to protect the eyes. Third, primates reduced the olfaction that is not useful for arboreal life. Fourth, comparing to the other mammals, primates have large brain consider to the body size. The large brain helps them to process the complicating reactions, and thinking. Haplorrhines primates have some unique derived traits: the loss of tapetum lucidum, which enhances the vision in the darkness; and haplorhini, which is dry external nose. The anthropoid primates have developed some derived traits. They have postorbital bar with closure, and this makes a complete bony ring surrounds the eyes. They also have fused mandibular symphysis. The Platyrrhines have the dental formula 2.1.3.3/2.1.3.3. The Catarrhines have dental formula 2.1.2.3/2.1.2.3. The Cercopithecoids have the bilophodont molars to enhance the chewing ability. The hominoids are the most developed primates, which have some derived unique traits. They have larger brain, loss of tail, longer arms than legs, broad thorax with more muscles, and highly mobile shoulder.

Primates first evolved from the trees of tropical forests, later to the ground. Through the times of promisians to human, many characteristics has been represented due to the adaptations to new environments and resulted in evolutionary changes. The Earth has encountered several geological and climatic changes over time. For the primates existed at that time had to adjust itself especially in body configurations and locomotion in order to better survive. It is important to be aware of this information since we are the part of occurring changes as well. Throughout the evolution owing to

Homo floresiensis (“Man of Flores”) is the name for a possible new species in the genus Homo, remarkable for its small body, small brain, and survival until relatively recent times (www.en.wikipedia.org). Anthropologists Peter Brown of University of New England in South Wales, Australia, Michael Morwood and their colleagues have argued that a variety of features, both primitive and derived, identified LB1 (the first skeleton found in cave of Liang Bua) is that of a new species of hominin, Homo floresiensis. The first specimens were discovered by Thomas Sutikna and colleagues from the Indonesian Research Centre for Archaeology in Liang Bua cave of Flores, Indonesia in September of 2003

Introduction This first lecture is designed to introduce the primate order in terms of its classification and to familiarise you with the animals so that the rest of the course makes some sort of sense. I will cover a working definition of what makes a primate, give you a general classification scheme, describe the major features that identify the groups within the classification and discuss some of the controversial areas of the classification. I shall treat the taxonomy as a synonym for classification which seems to be its commonest current usage, although you should be aware that some people consider taxonomy to be more about the principles behind the classification than the classification itself.

There is a circumstance that has beset the understanding of evolution over time that there is no general theory involving primate evolution. Most of the theories are just mere speculation. Over the years, primates like gorillas, chimpanzees, and baboons all happened to have their turn in evolution. It was previously presumed that the taxon of interest happened to have the exact similar physiology and ecology as the analog taxon (Rafferty, 2010).The majority of the first primate species theories have been utilized because they solely share one fundamental characteristic with the hominines with the chimpanzees as the phylogenetic cousins. This paper addresses the different ecological conditions that handled the evolution of primates. It

Both humans and other primates use tools, and in similar ways as well. Many use tools for gathering food or hunting. Though humans have a larger array of tools, for many more complex uses. No other primates use tools as much as humans do. Humans are very unique for

Burbacher and Shen did a study with forty-one infant monkeys at the Washington National Primate Research Center’s Infant Primate Research Laboratory (Burbacher). The birth weights of each infant monkey were within the normal range; the average birth weight was 341 grams and the range was 225-420 gram. Monkeys were weighed daily throughout the study, and any clinical problems were recorded. This experiment mainly compared the natural mentality and brain distribution of infant monkeys and the inorganic mercury in infant monkeys after the thimerosal were exposure with those exposed to methylmercury (MeHg). Monkeys were injected thirmerosal at birth and 1, 2, 3 weeks of age so they could get exposed to the MeHg. Infants were divided into

While the production of tools can be done by other primates, such as chimpanzees, it is nowhere near as complex as man-made tools. Other primates repurpose objects without actually creating anything. Humans can create advanced tools and use them for multiple purposes. The most basic stone tools have been dated to 2.3 million years ago in Lokalalei, Kenya. Humans started hunting large animals with wooden spears around 500,000 years ago.

One of the main reasons why we are so interested in the other primates is that by looking at them we can obtain some ideas of what our ancestor must have been like a few millions years ago. Even though, we are not descended from any modern-type monkey or ape, our lineage does appear to have gone through stages in which we were a medium-sized, reasonably intelligent creature with good binocular vision, hands that were good at manipulation and the ability to climb trees. An evolutionary trend in primates involves the development of offspring both before and after birth and their integration into complex social systems. Another trend in primate evolution has been toward a more elaborate brain. In addition to brain size and gestation periods,

Many people, before the discovery of Homo floresiensis, assumed Homo sapiens were the only living species of the genus homo since Homo erectus. The 2003 discovery of “the hobbit” in a limestone cave in Flores, Indonesia changed the way people today view much of the timeline of early human evolution. The island of Flores was assumed to have never been connected to any mainland, bringing to question how this species arrived on the island in the first place as well as what the island looked like at the time. There were several physical characteristics such as leg length and brain size that made the discovery of Homo floresiensis so special. The bones found were dated to 18,000 years ago, astoundingly recently (Brown). To this day, it is unclear how this species evolved to be so small. Scientists had developed several different theories but have frequently come to the conclusion that these humans were affected by island dwarfism (Morwood). The environment in which Homo floresiensis lived, their physical structure and the recency of their existence holds many mysteries around why they were so small and what impact the above factors had on the hobbit’s overall size.
