Alfred Wegener : born on November 1, 1800, was a German polar researcher
He suggested that a supercontinent he called Pangeahad existedin the past, broke up starting 200 million years ago
it appeared that Greenland had moved a mile away from Europe in a hundred years. And Paris and Washington, D.C., seemed to be moving apart by about 15 feet each year while San Diego and Shanghai got about six feet closer. On top of that, Wegener learned that related species, too small to swim the oceans, were found on different continents, as were similar fossils.
In 1912 he proposed that the continents we know today were once all attached in a single landmass he called Pangaea (Greek for "all earth")
evidence seemed to match up: the shape of the continents, fossil evidence, matching rock types and geologic structures, and evidence of ancient climate patterns
he tought of the Earth almost fit together like a jigsaw puzzle
Wegener died in Clarinetania, Greenland, in November 1930
