Hint: During one or more episodes of geologic time, continental drift, large-scale horizontal motions of continents relative to each other, and the ocean basins. This idea was an important precursor to the growth of the plate tectonics theory, which integrates it.
Complete answer:
Continental drift is the theory that the continents of the Planet have shifted relative to each other over geological time, thereby appearing to have 'drifted' around the ocean bed. In 1596, Abraham Ortelius first put forward the speculation that continents may have 'drifted'. Alfred Wegener introduced the idea independently and more thoroughly in 1912, but many dismissed his theory because of the absence of any motive mechanism. For that mechanism, Arthur Holmes later suggested mantle convection. The theory of plate tectonics, which explains that the continents shift by riding on plates of the lithosphere of the Earth, has since subsumed the principle of continental drift.
Species were divided by seas and oceans as continents broke away from Pangaea, and speciation occurred. Individuals that were once capable of interbreeding were separated from each other reproductively and ultimately developed adaptations that rendered them incompatible. This, by developing new organisms, drove evolution.
Continental drift affects the history of life on earth, By splitting the continents into various geographical circumstances. Alfred Wegner suggested the Continental Drift hypothesis in 1912. According to this theory, the land of Gondwana, South America, Australia, was divided into various climatic conditions. The history of life is influenced by complex climatic conditions. It is backed by the comparable fossils of that time in these continents.
Note:
They pass into new climates as the continents drift. What was at the equator once could now be close to the poles. If animals in the weather and temperature could not adapt to these changes, therefore they will not survive and go extinct. New organisms in the new areas will take their place and learn to survive.
