Some people believe in the Bering land bridge, and others believe humans already inhabited the Americas long before the ice age. But I am here to express my opinion about the first Americans.

The first Americans migrated from Siberia and Alaska. It is said to believe that people had lived on the land bridges. (Fagan, Gammon and Fraser, 2017) Due to temperatures rising most of the land bridges had melted and sank under the water's surface around 12,000 years ago. According to pollen samples, deep-sea cores, etc, we know that around 30,000 years ago the landscape was a rather more comfortable setting for the hunters and gatherers in the Northeast Asia. The large terrain had many benefits involving many different large and smaller animals for food and offered many trees to be used as fuel for a fire or a light source. Around 30,000 years ago, climates in Northern Asia became extremely cold and dry, and there is evidence for a large-scale abandonment of much of the region. (Fagan, Gammon and Fraser, 2017) The land bridge would get warmer and colder at certain times, so in the colder times, plant production made it difficult …show more content…
If so it is wondered where or if it even were the only place that could. Thanks to deep-sea cores and research on islands around where the strait was we now know much more about that time period and how the natives traveled from Asia to Alaska. With the cores having things like diatoms, minute shells, and pollen they reveal more of a colder more rough terrain than there would be in Siberia at the time. Beetle remains have been found in the cores that show that even at the worst of the glacial period were about the same temperature as they would be today if you went there. The reason for this is the influence of Northern Pacific currents that were blown in and brought warmer and wetter conditions to the land bridge. (Fagan, Gammon and Fraser,

Bridge

...Bridge Bridges was made for crossing over a large body of water or land. The design of the bridge and its function are made based on the need of the situation. Early bridges are made from natural materials like “wooden logs, stone, and dirt.” Some said that the first bridge was made from nature, when a the log fell across a stream. Bridges made from natural resources tend to disintegrated over time. The Ancient Rome, then tried to improve the bridge by using volcanic rocks to make mortar. The new resource help the bridge to withstand against mother nature and helped the Romans to make more fancy bridges. The bridges they built are more powerful, sturdy, and larger than any bridges before. The idea then spread across Europe to Asia and Africa. The design of the bridge across the world has varied from place to place. Due to circumstances and situation that the place needed.

Plate Tectonics

...The History of Plate Tectonics The Theory of Plate Tectonics is the theory accepted today for how the Earth was shaped. It is fairly new compared to other theories explaining the features of the earth like Catastrophism, Uniformitarianism, the Contracting Earth Theory, the Land Bridges Theory, and the theory that Plate Tectonics Theory stemmed from, the Continental Drift Theory. In this essay, I will explain why Plate Tectonics was not widely accepted until 1968 and how the formation of the earth was explained before it. In the late 1700s, Georges Cuvier proposed a theory called Catastrophism which explains Earth’s features like mountains and volcanoes by summing it up to a series of catastrophes. The evidence for Catastrophism was legends...

The Origin of the Native Americans

...themselves to outsiders. Indians gradually became a mystery to other people. Nowadays, Indians prefer other people to refer to them as Native Americans. The reason is that they claim to be the original inhabitants ofAmerica; according to their tribe’s legends, they did not travel from other parts of the world to reside in America. On the contrary, many scientists and scholars have agreed on the Bering Land Bridge theory that the majority of Native Americans migrated to America from Asia via a land bridge between Alaska and Eastern Siberia around 20,000 years ago. There have been other theories involving the origins of the Native Americans. One theory suggests they were the descendants of the lost tribes of Israel while another says that they were an ancient Chinese people who migrated to America a long time ago. After comparing and contrasting these various theories, it becomes clear that the Native Americans most likely came from China via the Bering Land Bridge. These days, the most widely accepted theory among people about the origin of the Native America is the Bering Land Bridge theory. This theory was first hypothesized by the well-known Spanish naturalist named Jose de Acosta in the late sixteen...

Bridges

...BRIDGES A bridge is a structure providing passage over an obstacle without closing the way beneath. The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. The obstacle to be crossed may by a river, a road, railway or a valley. History The first bridges were made by nature itself—as simple as a log fallen across a stream or stones in a river. The first bridges made by humans were probably spans of cut wooden logs or planks and eventually stones, using a simple support and crossbeam arrangement. Some early Americans used trees or bamboo poles to cross small caverns or wells to get from one place to another. A common form of lashing sticks, logs, and deciduous branches together involved the use of long reeds or other harvested fibers woven together to form a connective rope capable of binding and holding together the materials used in early bridges. Dating to the Greek Bronze Age (13th century BC), it is one of the oldest arch bridges still in existence and use. Several intact arched stone bridges from the Hellenistic era can be found in the Peloponnese in southern Greece. The greatest bridge builders of antiquity were the ancient Romans. The Romans built arch bridges and aqueducts that could stand in conditions that would damage or destroy earlier designs. Some stand today. An example is the Alcantara Bridge, built over the river Tagus, in Spain. The Romans also used cement, which reduced the variation of strength found in natural stone...

Maynard Stow

...Empire State Building or the bow of the Titanic (before it sank). Maynard and Stow offer remarkably few opportunities to be in a place where distant vistas are a view. Once upon a time Summer Hill, now tree-covered and trail-crossed, was open pasture. History Society pictures taken as recently as World War II show an expanse with few trees. Decades earlier, state surveyors installed an official stone marker atop Summer Hill, with the expectation that from that point, clear viewing was available in all directions. Marble Hill, at 440 feet, the highest elevation in Stow, is similarly tree-obstructed. Stow does offer a hill with a present-day view. Stories hold that ships’ pilots in Boston harbor used the stand of pine trees atop Pilot Grove Hill as a navigational landmark, suggesting that in the reverse direction a person atop the hill could see Boston’s skyscrapers. Alas, not so. Mayhap from a treetop, but not from ground level. However, Birch Hill Road, elevation 370 feet, does offer a glimpse of Mt. Wachusett, twenty miles to the northwest. Bridges can offer vistas. White Pond Road over the Assabet River, on the Stow/Maynard border, offers good views up and down river – albeit less than a mile’s length combined. The bridge is 120-feet in length with a surface 10-feet above the water. Parking is not permitted, but there are places along the shoulder to pull over and briefly leave the car as long as one does not wander too far away. Over the course of the winter this stretch...

Australian Aboriginal Culture

...a rich history and incredible diversity. It has been home to one of the most ancient populations of people, rather appropriately known as the Aborigines, or “first ones.” These people lived in harmony with the land, resourcefully adapting to and drawing sustenance from the arid landscape. The isolated nature of the continent allowed the Aborigines to thrive, undisturbed, for tens of thousands of years, but the limited contact with outsiders left them unprepared for the arrival of European settlers that first appeared in the 19th century. Unfortunately, the Aboriginal culture and nomadic lifestyle was thoroughly misunderstood by the Europeans. The ensuing European colonization had a profoundly negative effect on the Aboriginal population of Australia, nearly destroying their culture and almost eradicating the entire native population. It is believed that during the last ice age, some 50,000-60,000 years ago, the sea level was much lower with a large portion of the Earth’s water tied up in glacial ice. A land bridge existed between Australia, New Guinea and the continent of Asia that provided a means of ground transportation for ancient travelers. This land bridge was subsequently submerged when the climate warmed, isolating Australia’s inhabitants. This is the one of the leading theories for the means by which Aborigines came to the oceanic continent (Grabowski 27). The Aborigines were a hunter-gatherer population that learned to live in harmony with the land. Because...

Carnegie saw all of the possible uses of this mass produced steel but before he could realize the materials potential he had to convince the public of its strength. He was charged with building the first permanent bridge to cross the Mississippi River by Tom Scott. Building the bridge utilizing this new processing of steel was what he needed. The bridge took four years to build and had many cost overruns. When it was finally completed no one would use his bridge because they were afraid of it collapsing. He had to come up with a way of convincing people it was strong and safe. He read that an elephant would not cross a structure that was not stable. He used this as a marketing stunt by setting up a parade to cross the bridge led by an elephant on its grand opening, it worked. Eventually, Andrew Carnegie...

...convince the minds of scientists. This became evident when scientist, Alfred Wegener presented the most significant geological theory of history. His model was the idea of continental drift, the strong argument that the continents had moved relative to each other in the past few hundred million years. His idea was eventually accepted by many geoscientists, but before the acceptance at the time there was immense antipathy towards his theory. Wegener lacked the ability to prove his theory; therefore the reaction of his model was aggressive and harsh. Dr. Rollin T. Chamberlin from the University of Chicago said, “Wegener’s hypothesis in general is of the footloose type, in that it takes considerable...

Mississippi Delta Museum Report

...History is an important aspect of our lives and although individuals may not realize it, understanding our backgrounds and our ancestors is also important. The Museum of the Mississippi Delta is the museum I chose to visit and I learned so much. It opened my eyes to multiple things that I had no idea even happened or existed in Greenwood, MS. Walking into the museum I expected to see exhibits about cotton and slaves, but it was much more than that. I noticed information on Native Americans, agriculture, and military. I walked around to different exhibits that were located in many different rooms, these rooms showcased different major events and people that were apart of Greenwood history. The Agriculture room was a major exhibit that stuck out to me because I thought I knew a lot of information in this field but I learned so much more. Agriculture has always been a major factor in MS; it provides us with jobs, land, and farming. Agriculture allows us to survive daily because it provides us with different products, food being one main one. Located in this particular exhibit were pictures that...

Philipines vs Malaysia on Sabah Claim

...Topic: Philippine vs. Malaysia on Sabah Claim Rationale of the study: Thinking of those possible controversial issues from the past that were not widely known regarding our country, we chose to focus on territorial matters; territorial disputes. Territorial dispute often refers to an opposition or contrasting of countries over a state of ownership in the land. Countries become as rivals for the sake of having a piece of land and contain the rights and power over it. This territorial issue is what our country had faced over a long period of time up to now. One of this is the Claim of Sabah between the Philippines and Malaysia which is what we are going to tackle onto our “Mystery in History”. Long ago, it is said that the Philippines and the island of Borneo, formed a land mass by means of the land bridges connecting the two areas. The North Borneo, now known as Sabah is confined to the Philippines. The Sulu inhabitants regarded it as “land below the wind” for it is located below the typhoon belt. Time came that the Borneo was separated from the Philippines due to lost of its land bridge. The two countries then fell under separate kingdoms usually called as sultanates. When the Spanish navy reached our shores, it influenced all the invaders to engage into different treaties with various sultans. One invader is the Malaysia. The main basis of the territorial dispute between the Philippines and Malaysia over Sabah is the different understanding and interpretation...
