Primate Evolution Hypothesis
Climate change had a heavy influence on nonhuman primate evolution. Modern primates live in areas with a warmer climate where forests tend grow thickly, mainly in the southern hemisphere. However primates used to have a much more diverse habitat, living in more areas of the world than they do today. This is directly a result of climate change which has forced primates to change habitats. Climate change also occurred multiple times between the origins of early primates and modern day primates however. For example "The Oligocene was an epoch of major geological change with resulting regional climate shifts that likely affected the direction of evolution" (O'Neil 16). Climate change not only relocated much of the existing primates but also cause …show more content…
The arboreal hypothesis, put forth by Smith and Jones, explains the primates characteristics as adaptations to a life in trees. Their 3d perceiving eyes, intelligence, and grasping hands/feet all working in tandem to make swinging from tree to tree more effective. The loss of a developed sense of smell in favor for these adaptations which were more important for the life in the trees.
The visual predation hypothesis asserted that the adaptations occurred to enhance the primates abilities to prey on insects/small creatures, which also happened to live in trees or forest undergrowth. Cartmill who was responsible for the hypothesis claimed the shift to life in the trees wasn't the most important factor to consider. However this hypothesis doesn't account for how primates evolved to better gather and eat fruit.
Sussman's angiosperm radiation hypothesis accounts for just that. Their hypothesis puts emphasis on the gather of fruit not insects. Sussman explains the visual adaptations occurred because of the poor visibility in the forest and a necessity for being able to spot fruit in trees. And their grasping hands/feet made eating fruit while hanging in trees
Climate Change Influences Nonhuman Primate Evolution
297 Words | 2 PagesClimate change influences nonhuman primate evolution in a number of ways. Fore example, in Central Asia, climates increased temperature by an insane amount. However, the issue among primates became that it was too dry of an environment and they were not able to survive. Primates among the northern hemisphere pretty much disappeared as a result of the increase in temperature of that period. Additionally, in South Asia and East Africa, tropical rain forests were being taken out and instead they would have grassy woodland areas, much less wet than the environment they replaced.
Bonobo And Chimpanzee Comparison Essay
300 Words | 2 PagesThe bonobo and the chimpanzee are physiologically very similar, so much so that bonobos were considered a subspecies of the chimpanzee for quite a while before they were destinguished as their own species. While the chimp is slightly larger, they are relativaly the same. They both are terrestrial and arboreal at times; The chimpanzee makes nests in trees at night. Though they look fairly similar, the bonobo and the chimpanzees vairy wildly when it comes to social and behavioural traits. Chimpanzees live in large groups of many male and female individuals.

Primate Climate Changes
210 Words | 1 PagesThrough 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.
Pleistocene Epoch Evolution
1355 Words | 6 PagesThe Pleistocene epoch, which occurred around 2.6 million years ago and lasted until about 11,700 years ago, was a time of severe global warming and global cooling. This period of time is known to have marked the most recent documented Ice Age. Of the five cited Ice Ages that have occurred since the beginning of time, The Pleistocene Epoch was the first to accrue humans. Moreover, the animals inhabiting the Earth throughout this era were predominately larger than animals living today. Given the facts, many have claimed that the animals existing in the time of the Pleistocene Epoch were genetic ancestors of the animals living in our present day; however, it can be more accurately presumed that it was within the Pleistocene Epoch that the evolution
Primate Monkeys
1111 Words | 5 PagesNon-human primate infants are usually seen in the wild interacting strictly with their mothers. The research question I proposed was, do infants interact mainly with their mothers, or do the males sometimes carry and feed the infants as well? In my research I wanted to observe all species that I saw. This included White Faced Capuchin Monkeys, Howler Monkeys, and Spider Monkeys. The first species I studied was the Cebus capucinus (white faced capuchin monkey)
Hominids Research Paper
518 Words | 3 PagesThe climate in Africa was experiencing a warming and cooling phase. From South Africa North of the Ethiopian Highlands the cooling a drying forced forests to contract and the Savannahs to spread. It was in this region that apes stopped living in the trees and had to learn to live in the Savannas and adapted to using two feet. Being bipedal increased survival by being able to use their arms for carrying food over long distances and avoiding predators.
Genus Homo Evolution
2186 Words | 9 PagesHumans use bipedal locomotion, yet there was a time in our ancestral history where a different mode of locomotion existed, which gives rise to the controversy introduced in this paper. Roughly 2.5 m.y.a. (million years ago), Homo habilis evolved from our closest ancestors, chimpanzees and gorillas giving us the first known genus Homo. Around 1.9 m.y.a. , and approximately 600 thousand years following the evolution of Homo species, a differentiation in gait occurred where; according to some, Homo erectus began running to acquire prey.
What Is Animal Cruelty In Elizabeth Costello's Essay
498 Words | 2 PagesBy studying how an ape would get a banana using “smart” methods can only prove a miniscule amount of their intelligence. Costello then says that “human ‘reasoning’” (PDF pg.44) is the only cause of what separates us from animals. In spite of that, I would have to say that this reason would show how humans have progressed more than any other animal. The basis of this proves that we have a better understanding of how things work over other animals.
Planet Of The Apes Book Review
859 Words | 4 PagesIn Dawn of the Planet of the Apes, the simian flu has wiped out the majority of humankind throughout the world and the apes have not seen any signs of human in “ten winter.” During the first scenes of this film we see how the male apes are out in the woods hunting for food just like the Cro-Magnon did in the past. It is also seen in the next scenes, when the male apes return home that Maurice is teaching the children by drawing on the cave walls and rocks resembling the traditions of the Cro-Magnon. These two examples show how evolution is inevitable no matter what species one might
Evidence Supporting Evolution
1856 Words | 8 PagesAlthough they walked like humans they were not as developed as humans today. They were short, had small heads, and brains that are one-third the size of a human’s brain today. The offspring grew quickly and reached adulthood earlier than today’s humans.
Annotated Bibliography: Hominins
1401 Words | 6 PagesScientists published the research of understanding the humans origins and got attention from all different countries, by giving them advice about early human ancestor can possibly live with a various of woodland community habitually eats included the food which is hard to chew like leaves and trees. In the other investigation from another scientist said Australopithecus sediba didn’t have a good structure for the mouth to eat in order to have a unfaltering diet of eating hard sustenance. However, a new research doesn't straightforwardly locate if Australopithecus sediba really has a close relative of early Homo for evolution, anyway it still does furnish better proof that the dietary progressions has formed those important and essential evolutionary for the humans nowadays. Researchers think that their investigation gives a truly corroboration of the contrast between rebuilding the animals who almost extincted and knowing those modification. The analysis of A. Sediba’s teeth gave scientist a big surprise to know two groups of different type must had been eaten hard substance like tree and leave before they disappear in this world.
Bipedalism Hypothesis
957 Words | 4 PagesAs a result, he predicted that early hominids were confined to drier areas of African land, which meant that bipedalism could have developed as a feeding adaptation. Also, Dr. Hunt noted that the “curved robust fingers and toes, mobile shoulders, and cone-shaped torsos were evolved from arm-hanging.” During bipedal harvesting, the curved robust fingers and toes gripped the branches. The mobile shoulders and cone-shaped torso worked to relieve stress on the body while these specimens hung by one-arm. These traits are found in early hominin populations (ex.
Cenozoic Era Research Paper
391 Words | 2 PagesGrasslands continued to expand and forests dwindled during the Miocene. Kelp forests made their first appearance and soon became one of Earth 's most productive ecosystems. Apes also arose and diversified during this epoch. By the end of the Miocene, the ancestors of humans had split away from the ancestors of the chimpanzees to follow their own evolutionary path. The Pliocene epoch looked similar to Earth today as North and South America had been drifting closer.
Australopithecines Human Evolution
445 Words | 2 PagesSmall teeth in australopithecines revealed that their diet was based on C4 plants, such as grass and sedges (Eadie, 2015, 10/07/2015). This reinforced the idea that our ancestors, the australopithecines, spent more time on ground because they ate things from the plain rather than from the forest (Eadie, 2015, 10/07/2015). Even though such traits of australopithecines suggested they spent more time in the plane they also spent time sleeping on the trees for their safety (Eadie, 2015, 10/07/2015). The skeleton of australopithecines informs us a lot about their social structure. For example, their small canines indicate that they no longer needed to fight as much for mates or to protect or get territory (Eadie, 2015, 10/07/2015).
