Alfred Wegner proposed the continental drift hypothesis using key observations. Wegner observed that all these continents fit together. He found that the eastern coast of South America fits perfectly with the western coast of Africa. Additionally, there is supporting evidence that similar rocks and structures show up on parts of different continents to inspire Wegner to believe the super continent was made of South America, Africa, Antarctica, Australia and India. Alfred Wegner found key evidence that fossils of animals and plants were found on continents that are separated by a vast ocean. These animals and plants were not able to move or migrate distances because they could not swim across wide oceans to get to a different continent, adding
In 1596- Abraham Ortelius took note that the coastlines of the continents seemed to be too fitting together. He initiated a theory that stated that the continents were probably joined at one point in time and were torn apart between Europe and Africa. In the year of 1912, Alfred Wegener stated that the continents were once joined in a supercontinent called Pangea.
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.

Who proposed that all of the present continents were once joined together in a single supercontinent called Pangaea?
Because of Pangia humans ended upon 2 continents, Pangia was 1 big super continent. Why they went here is because their food was on those two continents. The original humans food was on Africa and Asia while tetonic plates were moving faster.
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.
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
Dee Brown's Bury My Heart at Wounded Knee was first published in the United States in 1970. This landmark book—which incorporated a number of eyewitness accounts and official records—offered a scathing indictment of the U.S. politicians, soldiers, and citizens who colonized the American West.
Millions of years ago according to scientist the whole world was one large mass called Pangea. When this mass began to split, it divided the Americas from the Eastern World along with the people on it. This resulted in tens of thousands years apart from one another which led to different developments on each continent. After all these years though a man named Columbus’s discovers the Americas in 1492. As soon as he took
Old worlds and new worlds was carried by the drift that was the continental, splitting from Eurasia and Africa is
Alfred Wegener was a meteorologist and astronomer. He was the first scientist to introduce the theory of the continental drift. Wegener theorized that at one time the continents were one large landmass or Pangaea that had drifted apart. His ideas were initially rejected by other scientists. It was not until long after Wegener’s death that proof was obtained and his theory verified.
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.
This geographic proximity and past physical connections mean that plants, animals, peoples, and ideas have been able to move between the two hemispheres with relative ease (xi). So in many ways it was the ocean floor that drew the first north Americans to migrate from Asia. The once water covered floor "had accumulated the natural fertilizers of sea animals and plant remains, on which grew lush forage that lured animals from Asia; the animals lured men" (Brown 23).
Charles Darwin began his scientific breakthroughs and upcoming theories when he began an expedition trip to the Galapagos Islands of South America. While studying there, he discovered that each island had its own type of plant and animal species. Although these plants and animals were similar in appearance, they had other characteristics that made them differ from one another and seem to not appear as similar. Darwin questioned why these plants and animals were on these islands and why they are different in ways.
The Scarlet Letter Critical Analysis Nathaniel Hawthorne was born in 1804 in Salem, Massachusetts, the direct descendant of John Hawthorne, and a judge at the infamous Salemwitchcraft trials. The guilt that Hawthorne felt over the actions of his ancestor had an enormous impact on his writings. In his introduction of "The Scarlet Letter", Hawthorne accepts the guilt from his forefathers and offers to repent for their crimes (Waggoner, 5). This unusual way of viewing guilt and sin is one driving factor in Hawthorne's writing. The other, which is closely related to the first, is the relationship between men, and of man to humanity as a whole.
