What Would Happen If There Are There Animal Fossils

2. The theory of “Pangaea” exists suggesting that the continents were once nestled together into one mega-continent. The continents then spread out as drifting islands.

Geologists believe that over 200 million ago, continental drift carried the Old World and New Worlds apart, splitting North and South America from Eurasia and Africa, eventually creating two separate biological worlds (Crosby, 2009). In 1491, the Atlantic and Pacific Oceans were nearly impassable barriers, and America might as well have been on another planet from Europe and Asia (Morris, 2011). However, when Christopher Columbus and his fellow voyagers made land in the Bahamas in 1492, the plant, animal, and bacterial life of these two worlds began to mix, and the world as we knew it would be forever changed (McNeil, 2008).

Between 280 million and 225 million years ago, the earth’s previously separated land areas became welded into a landmass called Pangaea. About 120 million years ago, due to the continental drift, this landmass began to separate. It split the old world and the new world apart, which dividing North and South America from Eurasia and Africa. The separation lasted for million years that it fostered divergent evolution. The new world and the old world’s biological evolution followed individual paths, becoming two separate biological worlds. However, after 1492, human voyagers reversed this tendency. In October 1492, Christopher Columbus and his crew landed in Bahamas. After Columbus arrived in

About 200 million years ago there was one big continent called Pangaea. They believed that, this landmass began to separate. They believed that the Atlantic Ocean formed, dividing Africa and Eurasia from the Americas. Over the next several million years plants and animals changed and made to separate biological worlds. It wasn’t until Christopher Columbus and his crew sailed to the Americas in October 1492, they started interacting with each other.

The theory of Pangaea suggests that the continents were once stuck together into one huge continent. Eventually they started drifting into separated landmasses, which gave birth to the modern continents.

Back about 21,00 years ago there was one big continent called Pangia. Then plates started moving, the ice age happened, Land bridge formed then disapered.

This shows that civilization started in Africa. As much as Europeans try and take everything from us Africans and rewrite our history as far as the Christopher Columbus era, it does not matter because artifacts shows that everything was started in Africa. We use ways of knowing to prove that between the bones found in Africa there was civilization in ancient Africa. “Experiential Kin is when you grow up with someone, even though your not blood family that’s your cousin. You don’t have aunts or uncles like in America. You have the nucleus family then the extended family.” This is the reason villages were so important in the uprising of Africa.

Geologists believe that between 280 million and 225 million years ago, the earth’s previously separate land areas became welded into a landmass called Pangaea. About 120 million years ago, they believe, this landmass began to separate. As this happened, the Atlantic Ocean formed, dividing the Americas from Africa and Eurasia. Over the course of the next several million years in both the Americas and in Afro-Eurasia, biological evolution followed individual paths, creating two primarily separate biological worlds. However, when Christopher Columbus and his crew made land in the Bahamas in October 1492, these two long-separated worlds were reunited. Columbus’ voyage, along with the many voyages that followed, disrupted much of the biological segregation brought about by continental drift.

who had traveled to America during the last ice age using the broad landmass, Beringia which connected North America and Asia. To solve this mystery, anthropologists came up with different theories to try and explain the differences in physical features. It is the discovery of Naia, a 12,000 to 13,000 year-old skeleton that helps them to make the connection.

Most theories of how the American continent was populated date back thousands of years and are brought up by evidence such as bone structure, genetics, skeletons, and weather patterns. Although some religions and tribes have opposing theories not based on cold hard facts but beliefs. To begin, the Clovis theory states that around 16,500 years ago modern humans migrated from Southern Siberia over the Bering Land Bridge that connected the American continent to the Asian continent. This theory is based off of genetic findings and past knowledge of weather patterns, earth’s movements, and the tectonic plate theory. To continue, the second theory is that African people

Have you ever wondered how people got to North America in the first place. Some people say that there used to be land that connected Alaska and Asia. Others say that it is not geographically possible. I agree with the theory that the Native Americans came over to America across the bering land bridge. Even though there is no land there anymore, there is still a lot of evidence that supports that it used to be there.

As we all know, the founder of the North America and South America is a voyager whose name is Christopher Columbus. After having read the story of the famous merchant-Marco Polo, he became to looking forward to the land of wealthy and mystery-China. He believed that the earth is round so he decided to sailed west from Europe, then he would reach the Asia. But he didn’t land on the land of the China, he found the new land instead. After he found the America, there are lots of common on his discovery. Then they divided to the different opinion, the positive and the negative.

Although thousands of years have shrouded the Peopling of the Americas in mystery, many archaeologists can agree on several basic factors. For example, All archaeologists agree that the Americas were initially migrated to during the late Pleistocene period, which ended 11,700 years ago and marked the last glacial period, but the specific dates and origins are still contested (Dixon 2003). The environment during this time was marked by distinctly low sea levels and both the emergence and melting of alpine glaciers, which blocked many migration routes (Other Migration Theories). Additionally, only three main origin hypotheses are generally identified as the most credible possibilities among the scientific community. The hypotheses are as follows: (1) the Ice-free Corridor Hypothesis, (2) the Solutrean Hypothesis, and (3) the Pacific Coastal Group Hypothesis. The scientific community, however, is not the be-all and end-all; many Native American groups propose another more culturally-inclined hypothesis.

During the Tertiary period, there were three oceans and seven continents. The three oceans were the Pacific, Atlantic, and Indian. The seven continents were Eurasia (Europe), North America, South America, Africa, India, Australia and Antarctica.

Other samples of the clay were taken to laboratories to be analyzed. Part of the results showed a large concentration of platinum and iridium. These elements are very rare on the surface of the earth at the moment but they are present in meteoric dust that rains down from space at a known rate. That rate allowed for a measurement of how long it took for the clay to form.
