The physical nature of a primate body as wells as its movement is a unique factor in the animal kingdom. There has been continuous change through locomotion and body configuration throughout each grades of primate evolution. In this essay I will be discussing the modifications in time as well as theories in each grade of primate. This research paper will try to elaborate on the evolutionary modifications and some of the theories that have been proposed for these changes throughout our and other primate evolution. With time primates development was due to environmental changes. Through each grade of primate we can gain a better understanding of primate evolution. Changes in body structure are especially significant in primates for purposes of
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 I have chosen was written by Helen Pilcher and is about evolution of creatures, especially for primates. However, until now, what do our very first primates were like still remain mysterious as we do not have sufficient information and evidences which are 60 million years ago. Yet, we still cannot deny that evolution occurs in creatures. No matter for humans, animals or plants, all of them will make changes because of their living habits and environment in order to survive. In this article, the author explains everything clearly about the primate evolution was taken around million years ago and ancestors are a small and nocturnal creature.
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
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 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
The second theory used to explain the origin of primates is the visual predation hypothesis. This theory states that, the ability to move
Climate change influenced nonhuman primate evolution by forcing the evolution of species and creating new environments that allowed for primates to live. "A rapid temperature increase around 55 mya ... led to an expansion of evergreen tropical forests, the environment that made possible many mammalian groups, including primates." (pg. 260). As rapid temperature increase created new environments a rapid cooling in the beginning of the Oligocene limited the range of habitats greatly. Due to this reduction a majority of the primates during this time lived around the fayum region in northeast Africa.
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.
The illegal hunting and trade of primate meat is a large contributing factor to the decline of primate species in the tropics. This, in addition to habitat loss and fragmentation, disease, and the pet trade, is putting many primate species at high risk of extinction. Poverty, population growth, construction of roads, emergence of regional and international markets, and new hunting technology are triggering the increased hunting pressure on forest mammals. Primate species are especially vulnerable to increased hunting pressure because of their slower reproductive cycles. The decline of primate species must be stopped to avoid their extinction and the potential consequences that this could have for tropical forests.
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.
This theory considers the movement of life from the ground into the trees as the most important catalyst in the evolution of the ancestral primate. The essential features of the primate evolved because they were necessary and therefore had greater fitness for creatures swinging from branches. The visual predation hypothesis does not seek to debunk the arboreal hypothesis, but takes note that other arboreal mammals have not evolved in the same way as primates. Cartmill pointed to animals like the squirrel which does not have features such as advanced care of young.
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.
Studying primates could also help us better understand how our ancestors may have lived and how they may have socialized, foraged/ate, or raised
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.
