Alfred Lothar Wegener (1880-1930), the originator of the theory of continental drift. (Photograph courtesy of the Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany.) |

According to the continental drift theory, the supercontinent Pangaea began to break up about 225-200 million years ago, eventually fragmenting into the continents as we know them today. 〔W. Jacquelyne Kious and Robert I. TillingによるThis Dynamic Earth: the Story of Plate Tectonicsから〕 大陸移動説によれば、超大陸パンゲアは約2億年前に分裂を始めた。 |
As noted by Snider-Pellegrini and Wegener, the locations of certain fossil plants and animals on present-day, widely separated continents would form definite patterns (shown by the bands of colors), if the continents are rejoined. 〔W. Jacquelyne Kious and Robert I. TillingによるThis Dynamic Earth: the Story of Plate Tectonicsから〕 現在見られる動植物の化石の分布は、当時大陸が合体していたと考えると説明できる。 |
