There were scientists who supported Wegener: the South African geologist Alexander Du Toit supported it as an explanation for the close similarity of strata and fossils between Africa and South America, and the Swiss geologist Émile Argand saw continental collisions as the best explanation for the folded and buckled strata that he observed in the Swiss Alps. It didn't take a scientist to realize that his argument was ridiculous. He celebrated his fiftieth birthday on November 1, but shortly afterwards the team got separated, and he was lost in a blizzard. Being German wasn't Wegener's only problem; the arguments he used to support his hypothesis crossed into disciplines that were not his specialty. Eventually, 13 of these men would turn around but Wegener continued and got to the location five weeks after starting the expedition.
Wanting to return home as soon as possible, he insisted upon starting back to the base camp the very next morning. He went as the official meteorologist on a two-year Danish expedition. Wegener's theory was soon rejected because he could not propose a suitable mechanism to account for the supposed drifting of continents. Authorities are expert in the current view of their discipline. We have an image in our minds as to what they looked like the last time we saw them, and they are much different. Further, we have to be prepared always for the possibility that each new discovery, no matter what science furnishes it, may modify the conclusions we draw.
After a long but unsuccessful search for a university position in his native Germany, he accepted a professorship at the University of Graz in Austria. Wegener was one of the first to realize that an understanding of how the Earth works required input and knowledge from all the earth sciences. Tenacious by nature, Wegener spent much of his adult life vigorously defending his theory of continental drift, which was severely attacked from the start and never gained acceptance in his lifetime. Travelling under frigid conditions, with temperatures as low as minus 54 °C, Wegener reached the station five weeks later. Mendel proposed an alternative to blending where traits were inherited whole see. Wegener also found that the fossils found in a certain place often indicated a climate utterly different from the climate of today: for example, fossils of tropical plants, such as ferns and cycads, are found today on the Arctic island of Spitsbergen. Wegener also presented examples where fossils of exactly the same prehistoric species were distributed where you would expect them to be if there had been Continental Drift e.
Many scientists and cartographers had noticed that the landmasses of the planet fit together like a giant jigsaw puzzle—the most noticeable example probably being the east of South America and the west coast of Africa. Coal was found in Antarctica and Britain, areas that could never support coal formation today. Returning, he accepted a post as tutor at the University of Marburg, taking time to visit Greenland again in 1912-1913. An attachment to the status quo doesn't explain all of the criticism. One, we really don't see what whole continents look like in real time, and two, they move so slowly that people die before any noticeable changes can take place.
In 1909, a massive find of 65,000 more specimens of early Cambrian life was discovered in the Burgess Shale in British Columbia, Canada. During his time there he gained an interest in the ancient history of the Earth's continents and their placement after noticing in 1910 that the eastern coast of South America and the northwestern coast of Africa looked like they were once connected.

Might the similarities among organisms be due, not to land bridges, but to the continents having been joined together at one time? Wegener took an interest physical and Earth sciences and studied these subjects at universities in both Germany and Austria. Reaction to Wegener's theory was almost uniformly hostile, and often exceptionally harsh and scathing; Dr.
A couple of years before his death, Wegener finally achieved one of his lifetime goals: an academic position. If the continents of the earth move and grow, why don't we notice that? In addition to these duties he found time to write his famous book on continental drift. His research created a forward understanding of the technical and scientific logic before the shift was confirmed. After many delays due to severe weather, Wegener and 14 others set out for the winter station in September of 1930 with 15 sledges and 4,000 pounds of supplies. Wegener, Galileo and Darwin The main problem with Wegener's hypothesis of Continental Drift was the lack of a mechanism. Even if I only arrived at the idea due to the correspondence between the coastlines, the documentation will naturally have to be based on material from geological observation.
Only early scientists like Galileo needed to fear the reaction to their radical views. A year before his untimely death, the fourth revised edition 1929 of his classic book was published; in this edition, he had already made the significant observation that shallower oceans were geologically younger. One of Alfred Wegener's critics, the geologist R. For example, Wegener mentioned , ancient climate similarities, fossil evidence, comparisons of rock structures and more. He died during his last expedition to Greenland in 1930.
