All of the observations listed were present in Wegener's original theory of continental drift. Wegener proposed that the shapes of the continents America and south America fit together, and he also noted the presence of large mid-ocean ridges where the new ocean floor was made and evidence that earthquakes occur to great depths in subduction zones. He also pointed to the presence of similar fossils on different continents as evidence for his theory.
Wegener's theory was not widely accepted at the time due to a lack of a satisfactory explanation for the mechanism that would drive the movement of the continents. It was not until the 1960s and the plate tectonic revolution that a more complete understanding of the movement of the Earth's crust was developed, incorporating the observations that Wegener had made.
Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each different, therefore performing to have "drifted" throughout the seabed. The concept of continental drift has been subsumed into the science of plate tectonics, which studies the motion of the continents as they ride on plates of the Earth's lithosphere.
The speculation that continents may have 'drifted' turned into the first recommendation through Abraham Ortelius in 1596. A pioneer of the current view of mobilizing changed into the Austrian geologist Otto Ampferer. The idea was independently and extra completely advanced by using Alfred Wegener in 1912, but the speculation turned into rejected by many for loss of any motive mechanism. The English geologist Arthur Holmes later proposed mantle convection for that mechanism.
