Final answer:
Alfred Wegener wrote 'The Origin of Continents and Oceans' in 1915 and hypothesized the theory of continental drift.
Step-by-step explanation:
Alfred Wegener, a German meteorologist and astronomer, wrote a book called 'The Origin of Continents and Oceans' in 1915. In this book, he proposed the theory of continental drift, which suggests that the continents were once connected and have slowly moved apart over time. Wegener's evidence included the fit of the continents, matching fossils and mountain ranges, and paleoclimate evidence. His hypothesis was initially met with skepticism, but it laid the foundation for the development of plate tectonics in the future.
