Alfred Wegener, a German meteorologist, proposed the theory of continental drift in 1912. According to this theory, all the continents were once joined together in a single landmass, which Wegener called Pangaea (meaning "all lands" in Greek). About 200 million years ago, Pangaea began to break up and the continents started to drift apart.

Wegener's theory was based on several pieces of evidence:

1. Fit of the Continents: Wegener noticed that the coastlines of some continents, like South America and Africa, seemed to fit together like pieces of a jigsaw puzzle. This suggested that they were once joined together and have since drifted apart.

2. Fossil Evidence: Fossils of the same species of plants and animals have been found on continents that are now thousands of miles apart. For example, fossils of the reptile Mesosaurus have been found in both South America and Africa. This suggests that these continents were once connected, allowing these species to inhabit both areas.

3. Rock Formations and Mountain Ranges: Similar rock formations and mountain ranges have been found on continents that are now separated by oceans. For example, the Appalachian Mountains in North America are similar in age and structure to the Scottish Highlands in Europe. This suggests that these areas were once part of the same landmass.

4. Climate Evidence: Evidence of past climates, such as glacial deposits in Africa and coal deposits in Antarctica, suggest that these continents were once located in different positions on the Earth's surface.

Despite this evidence, Wegener's theory was not widely accepted during his lifetime. It was only in the 1960s, with the development of the theory of plate tectonics, that the idea of continental drift became widely accepted in the scientific community. Plate tectonics provided a mechanism for continental drift, explaining how the continents could move across the Earth's surface.
