Human Primates, Humans, And Humans

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,

The studies of primate evolution have been developing throughout the years and now scientists are able to compare and contrast between several types of primate groups. One notable primitive characteristic that non-human primates and human primates have retained is the development and evolution of their dentition. Due to primates having long growth periods, scientists are able to research how primates have different dental characteristics and specializations in modern time (Larsen, 2008). By analyzing teeth, scientists are able to determine several factors, such as similar dental formation, growth, development, and diet preferences (Larsen, 2008).

The study of primates has been a common field of study for a long time. The studies are carried out for different reasons but the common reason is trying to understand human beings better. Studies have revealed that the behavior of primates is similar to that of human beings on different aspects. Human beings and primates have a history of being related based on the evolution stories. The earliest human beings are believed to have been apes and evolved from there.

For many animals, the ability to move is essential for survival. Animals move for a variety of reasons such as: to find food, a mate, a habitat to live in, or to escape predators. It is important for animals to develop new abilities and traits to accomplish these necessities of living. Natural selection has shaped the locomotion methods and mechanisms used by moving organisms for millions of years. Generally, non-human primates are studied to garner an understanding of evolution caused by natural selection because of the many distinctive adaptations that have occurred within their taxonomic order. To understand the origin of locomotion that exist amongst primates, the two categories of primates must be analyzed to recognize morphological trait differences. Then, three major determinants can be evaluated to describe the variety of locomotor patterns primates display: the ecological niches in which the primate originates, the current inhabited niches, and the major key aspects of survival such as

Experiments and research on non-human primates has helped advance the fields of biology and medicine. The experiments and research done on primates often plays a major role in testing the safety of new drugs, research on understand how the brain works, and research on how to prevent infections disease in humans. Thanks to research done with animals, medical advances are continuously made. In some way, all humans benefit from animal research. Non-human primates are a group of mammals that consists of monkeys, apes, chimpanzees, lemurs and others. Monkeys are then divided into two smaller groups known as Old World monkeys and New World monkeys. New World monkeys are native of Africa and Asia. Old World monkeys originate from Central and South

Muireann Quigley, in his article, “Non-Human primates: the appropriate subjects of biomedical research?” discusses the ethical issue of whether or not we should be using non-human primates in biomedical research. Throughout this article, Quigley raises the question is it ethical to perform testing on non-human primates? By looking at the accuracy of this testing, the type of research done, and the capacity of the subjects we can see that if the experiment is not ethical to perform on a human then it is not ethical to conducted on a non-human primate.

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

The major primate groups are divided into two groups. The first main group are the Strepsirrhini’s, also called prosimians and include, Lemurs, Lorises and Galago’s. The second main group of primates are called haplorrhines and include, monkeys, apes, and humans

“Non-human primates, due to their level of intelligence when compared to other animals, and also due to their evolutionary closeness to man are maintained in several types of captive facilities like laboratories, zoological parks, animal circuses and conservation breeding centres” (Mallapur 2005). Non-human primates are the closes species to human-kind compared to others. The intelligence they contain and their relatively comparable behaviors they have with human-kind make them a fascinating study. They are kept for observation and research; but many of the enclosure sceneries evoke abnormal behavior patterns among non-human primates. Maintaining a satisfied non-human primate in captivity can be challenging.

One of the most fiercely debated issues in paleoanthropology points at the origins the primate species. The top two continents that have been very evident in our origins that can be traced to Africa and (Eur)Asia. African origin stresses the multiregional continuity theory it suggests a single origin for modern humans and gives an explanation to the Out-of-Africa model for the patter of our human evolution.

The first true evolution of primates goes all the way back to 55 million years ago.. Primates descend in two orders, Stepsirrhini and Haplorrhini. The Stepsirhines were the first of the suborders to unfold. That term is identical with prosimians. Prosimians are defined as a “pre-monkey” in Latin(anthro.palomar.edu). Evidence was not shown until the 20th century of prosimians evolving before the monkey. A stepsirhine that is still alive and studied today are lemurs. Lemurs are the oldest ancestors of monkeys, apes, and humans. There is research of a Lemur’s past and present habitats, discovered theorists, predators, diet, life expectancy, large number of subspecies, and fossils collected about Lemurs.

On modern earth there are five basic groupings of monkeys and primates that relate to physical attributes. These groups are called Prosimian, tarsier, new world monkeys/old world monkeys, apes and hominins. Humans are featured in the super family known as hominoideas, this family includes both apes and hominins. Apes are described as having large bony eye ridges and flattened noses. The term hominin refers to the more human apes that contain examples such as orang-utans, gorillas, chimpanzees and humans. Hominids generally have quite large bodies and bigger brains than most other primates, humans differ to all other hominins as they are bipedal and all other hominin are predominantly quadrupedal but all hominids possess bipedal shaped

Animal experimentation happens everywhere, we think since animals have similar structures and organs as us it’s easier to experiment on them but does it make it right? Something the public might not know is we already experiment on people. No matter how many times we test on animals there's always going to be someone that will always be the first human to try it. The most popular animals to be tested on being primates because of how similar, there are to the human body. Primates are basically many types of monkeys like a Chimpanzee's. Primates are very different from other animals because of their not a normal animal that could just live in your house there from the wild. For example “ studies demonstrate that they have mathematical, memory,

Human evolution is the gradual process in which people, or Homo sapiens, originated from apelike ancestors. Scientific evidence, particularly in the form of fossils and secondary remains, show that the physical and behavioral traits shared by all people evolved over a period of approximately six million years. Humans are primates. Both genetic and physical similarities show that humans and the great apes (large apes) of Africa, chimpanzees (including bonobos, or so-called “pygmy chimpanzees”) and gorillas share a common ancestor that lived between 8 and 6 million years ago. The volume of fossils found in Africa suggests that most evolution occurred there and is likely the place of origin for early humans. This brings to fruition the “out of Africa” theory, also called the “single-origin hypothesis.”

Humans have existed on Earth for approximately 3.4 million years. The oldest known human ancestor is "Lucy," an Australopithecus. Over this extensive period of time, humans have evolved significantly. Homo Sapiens have grown from 3 to almost 6 feet (average), lost most of the body hair, became leaner and adapted to walking. Humans have come a long way, from Australopithecus to Homo sapiens, from living in trees to living in cities. Slowly, through hundreds of thousands of years, we mutated over and over again, natural selection ensuring that no destructive mutations continue. From the slow evolution, four distinctive species emerged and died out, each giving way to its ' descendant: Homo Habilis, Homo Erectus, Homo Sapiens Neanderthalesis, and Homo sapiens Sapiens.
