Alfred Wegener was a geophysicist and meteorologist that defended that once all the continents were joined together in an called “Urkontinent” before breaking up and drifting to their current positions. Once the plate tectonics was discovered Wegener theory became less far fetched because it reassured that he was right in his assumptions about similar fossils and rocks in different continents.
there was a fossils of a linguistic rule that was active in an earlier period, or in a language from which the words were borrowed, or they might arise by sheer chance.
