The primate freedom organization protects primates from inhuman experimentation in hopes to stop animal experimentation. They also donate Primate Freedom Tags and provide research to other organizations. Finally, they write articles for campus publications, foster community, and campus-based Primate Freedom Projects, and work to connect all primate freedom efforts
The article, “Of Primates and Personhood: Will According Rights and “Dignity” to Nonhuman Organisms Halt Research?” by Ed Yong is trying to convince the reader to see a different side to primates. The Great Ape Project set legal rights for chimpanzees, gorillas, bonobos, and orangutan. United Kingdom and New Zealand protect great apes from experimentation. For the Great Ape Project they are basically setting laws and higher standards for primates to me experimented on or held captive.
When reading in chapter 9 about “Geology and Primate Origins”, I came to a decision to choose the relative dating techniques. It is dating techniques that establish the age of a fossil only in comparison to other materials found above and below it. Relative dating techniques use the principles of stratigraphy to tell us how old something is in relation to something else without applying an actual chronological age. An example of this technique is biostratigraphy (faunal correlation), biostratigraphy is a relative dating technique using the comparison of fossils from different stratigraphic sequences to estimate which layers are older and which are younger; employed in the Early Pleistocene deposits at Olduvai and other African sites. The prime
The theories of early primate evolution are Arboreal, visual predation, angiosperm hypothesis. The Arboreal theory explains primates unique traits in adaption in trees while visual predation details the
The climate and it's different variable had many effects on the evolution of primates. It's obvious that when the weather changes, migration is necessary. When the weather changed, primates had to migrate, causing adaption to different environments. With each migration, new habitats were exposed to primates, giving them new ways of life. Enviornment change exposes new foods and new living accomidations.
These new environments made possible the evolution of nonhuman primates, and influenced the evolutionary path of primates. Three common theories of early primate evolution are the Arboreal Hypothesis, the Visual Predation
According to our textbook, Europe, Asia, and Africa experienced dramatic changes in climate and ecology. For example, a shift in tectonic plates created the Alps, Himalayas, and the East African mountains chains. Other examples of dramatic climate changes include the shifting of ocean currents and the development of the polar ice caps. Specifically in Europe and Africa, the once lush tropical forest changed to cooler, dryer woodlands and grasslands. Our book claims that as a result of such climate change, tropical foods like fruit (apes favored diet) began to disappear.
Primate evolution is very much driven by the changes in climate that happened throughout the time of their adaptations. Climate changes derived from one main source; the movement of tectonic plates. These tectonic plates that are constantly moving away from each other. In addition, the drifts in tectonic plates influence changes in climate because they moved large land masses away from each other to a different location which contained different climate statuses due to leaving them closer or further from the equator a huge decider of climate characteristics. Moreover with climate change, evolutionary adaptations came into play, with various species as well to one of the main features of primates which is their strategies and anatomical features
Through history there has been evidence to help support the claim that climate change has influenced the evolution of primates. Scientific evidence has proven that during certain climate spikes such as the swamp age, apes in the given territories that encompassed Africa led a migration to the Asia and Europe territories. The same climate changes that was responsible for the creation of the Swiss Alpes and other phenomena, has been associated with the adaptation, extinction, and migration. As weather changed in certain areas, the land became more dry making it harder to obtain and hunt food. Climate change, in theory, led to the extinction of the Sivapithecids apes because of the inability that the species has to obtaining food.
Today, the brain is said to be the most energy consuming and powerful organ in the body. Not only has the cranium grown tremendously over the years, but the brain processes have intensified as well. Cáceres states that with the various studies made by professionals to distinguish the human brain from a non-human primate’s brain, we have been given proof of the advanced neurological processes that the primate brain contains. (Cáceres, 2003) Along with these processes, primate intelligence has advanced through the development of cultural interactions, advanced tool and food technology, and through the progression of movement.
Adaptation is a trait developed within a species for the survival and the reproduction of an organism in its present environment. In this work, we are going to answer key questions on hands traits common to Chimpanzee, gorilla and human. The body will mainly focus on what makes this trait an adaptation, how the trait evolved; e.g., mutation, genetic drift, migration and/or natural selection. What is the difference between homologous and analogous traits? How does the trait of choice fit either of these descriptions?
Upon the creation of humans, part of our behavior has been genetic and others have been culturally shaped. These genetics help us relate to our ancestors the primates because it shows that we’re still evolving. Even though we have gone from Homo habilis to Homo sapiens sapiens, the heritage from chimpanzees and other primates is still visible. On the other hand, humans, like primates learn certain things according to the environment they may live on and how it affects them. The things someone picks up from observing or experimenting then turns to culturally shaped.
Lieberman formats his book in three distinct sections: Part 1-3. The first section, 'Apes and Humans ', broadly focuses on the pre-Neolithic hominin by particularly focusing on bipedalism, our large brains, and our ability to store excess energy. I find that I am more knowledgeably persuaded by the first section of the book, mainly with it being the section that I am least familiar with. This section is strategically written to allow the reader to have a full understanding of the major transitions in evolving from apes into modern humans.
The theory that man evolved from apes came about because of the similarities found between humans today and in fossils dating back over six million years. This can be shown in evidence that humans had a decrease in the size of the face and teeth. This can also be proven by the increased size of the human brain today. Early humans are classified in ten different types of families .Creationists believe that humans haven't always been in human formality. Humans are classified in the mammalian familial class which can also be classified as primate.
BIOLOGY RESEARCH ESSAY There is great speculation around evolution. As we are continually in the process of discovering the history of human beings, there are many questions surrounding this topic. One very interesting question is why ancient ancestors of homo-sapiens evolved to walk upright like we do today. An apes’ DNA is astonishingly similar to that of a humans, (97% the same) and yet, our bones’ shapes and structure are very different.
