primates were able to migrate from Asia to North America 56 million years ago because of huge volcanic eruptions, which released an ample amount of greenhouse gases leading up to an intense period of global warming. Because of this, the vegetation of North America began to change. The cool forests turned into tropical rain forests who kept their leaves all year round so they can provide food and shelter for these primates, allowing them to migrate to North America. At About 70 million years ago, a piece of earth’s crust under the Pacific Ocean dove down under North America making it rise creating the Rocky Mountains. As the Rocky’s continued to rise, the land under the inland sea was forced up and all of the water drained into what is now
The Rocky Mountains, also known as the Rockies, extends for some 3,000 miles (4,800 km), that covers land in two North American countries! With a distance of 3,000 miles, the Rockies must have a variety of physical features and landscapes that makes it an attractive area to tour and explore. However, all of the human interest in this mountain range could come at a devastating cost. Disturbances such as resource extraction, tourism/settlement, and farming in the Rocky Mountain region must cease because they are causing major, irreversible environmental degradation.
Primates are one of the most interesting mammals on earth, not only because of their complex social structures, but because they hold so many similar characteristics to humans. Primates are often cited as our closest living relatives and on two separate occasions I observed four separate species of primates at the San Diego Zoo that can justify their use of their physical characteristics and behaviors that may be similar as well as different to the other primates and ours.
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.
Anthropological theories concerning the peopling of North America is a topic that is widely debated. By far, Western scientists seem to agree that: “As a result of the vast amount of water that was locked up in glacial ice toward the end of the Pleistocene era, there was a worldwide drop in sea level of as much as 400 feet” (Sutton 19), creating a land link, known as the Beringia, between Asia and Alaska. Starting from this point about the land link, we find that Elias’s article “First Americans Lived on Bering Land Bridge for Thousands of Years,” is the most agreeable theory about the peopling of North America.
About 225 million years ago, according to the theory of “Pangaea,” the world was once a single supercontinent that contained all the dry land. Approximately 10 million years ago, North America was shaped by the majestic Canadian Shield. About 2 million years ago, in North America, the grand glaciers laid the land of Canada and the United States, southbound as far as from Pennsylvania all the way to the Pacific Northwest. Recently, about 135 million to 25 million years ago, four massive ranges—the Rockies, the Sierra Nevada, the Cascades, and the Coast Ranges, arose in western North America. About 35000 years ago, the ancestors of the Native Americans, the nomadic Asian hunters, first

Mountain men were most common in the North American Rocky Mountains from about 1810 through the 1880s (with a peak population in the early 1840s). Approximately 3,000 mountain men ranged the mountains between 1820 and 1840, the peak beaver-harvesting period. While there were many free trappers, most mountain men were employed by major fur companies. The life of a company man was almost militarized. The men had mess groups, hunted and trapped inbrigades and always reported to the head of the trapping party. This man was called a "boosway", a bastardization of the French term bourgeoisie. He was the leader of the brigade and the head trader.
It’s hard to think about living in pre modern times, with all the technology we have today. I have heard stories from my grandmother about when she was a young lady in Hazard. That was while coal mining was the big thing though. So for all my research I had to turn to other sources. When I think of pre modern I think of old television shows such as “Little House on the Para ire”. Simple times before industrialization made its appearance. In this essay, I am going to describe and compare the ways of pre modern Appalachia to nowadays. I am going to include topics such as: economic activities, transportation, housing and standards of living, women’s and family life, church, communities and social gatherings, and
Long before the Europeans discovered the Americas, the North American region went through a lot of geological and geographic changes. Originally there was just one super large mass of land but overtime that land broke apart forming continents. Shifting and folding of the earths crust formed mountains across North America and the rest of the world. One major change that the region of North America went through was during the period of the Great Ice Age. The Great Ice Age took place 2 million years ago. During the Great Ice Age, large glaciers covered North America (along with other continents). When the glaciers disappeared 10,000 years ago they left North America new and transformed. The changes that the glaciers made were forming of lakes,
The Appalachian Mountains spans from the state of Georgia all the way through the maritime within the provinces of New Brunswick, Nova Scotia, Prince Edward Island, Newfoundland and Eastern portions of Quebec. The land is primarily made up of sedimentary rock that was lifted up and folded, because of the collision of North America with Europe and northern Africa during the formation of Pangaea, creating mountains. These sheets of sedimentary rock are wealthy in non-metallic minerals such as coal. In addition, volcanic action and faulting formed igneous and metamorphic rock in specific space in the Appalachians. Plateaus made of this rock carry metallic material, because of this such as iron and zinc. Many land forms that may located here are
In 1739, 2 European men went on a quest to find a northwest passage through the Western Sea. They would have to track through much dangerous wilderness for many, many miles. These 2 men went forth to face all of this danger and the Indian country for the glory of France. This all led to the discovery of the Rocky Mountains. Sieur de La Verendrye had travelled through the west most of his life, and going where no white man would ever go. As he came old he decided to pass down all of his work to his devoted sons. Pierre and the Chevalier, they joined him on many of his journeys and knew that they would be able to do the job. Even though he failed to find a way to the Western Sea himself, he believed that his sons would be able to find a way.
Before examining how climate change has affected primate life, it is important to understand what exactly climate change is caused by. Essentially, climate change, or global warming, is the gradual increase in global temperature due to greenhouse gasses and deforestation. The way the global warming phenomenon has occurred is through the burning of fossil fuels, like petroleum and coal, for example. When they are burned they are sent into the atmosphere, damaging the layer of atmosphere that protects the earth. In addition, deforestation is the demolition of land and rainforest, which is home to most species of primates. The destruction of the rainforest not only destroys ecosystems, but releases even more carbon
Occurring about 12,800 years ago, The Younger Dryas Climate Event was an abrupt climate change that dropped the Earth temperature by about 10 degrees, bringing dry winds (“Abrupt Climate Change”, 2003). This event followed a warming trend that had resulted in glacier melting. As the melting water filtered down the Mississippi and into the Gulf of Mexico, its route suddenly diverted, carrying the water east into the Atlantic Ocean. This change in the water path disrupted both the salinity and the flow in the ocean system, thus changing the climate of the Northern region. Unfortunately, 30 species of animals became extinct as a result of the changes, and nearly 80 percent of North America’s large animals disappeared (video). Ending abruptly, the Younger Dryas officially
The prairies in North America formed as the Rocky Mountains grew taller and taller. They grew taller and taller because of plate tectonics, the process where a small number of plates on the Earth’s crust interact with each other. Once the mountains got tall enough, they blocked
