Geologic History And Evolution: The other major advance in zoogeography during the past year was the publication of a theory of island biogeography based on a synthesis of knowledge from various disciplines— population genetics, evolution, taxonomy, zoogeography, and ecology. Charles Darwin's observation of the faunas of islands, especially those of the Galapagos, played a key role in the development of his concept of evolution; through the years, insular biogeography contributed much to document the theory of evolution.
The distinctive features of a planet are its composition, structure, and geologic history and evolution. A good deal is known about these first two characteristics of the earth, but its early geologic history and evolution and development are largely lost because water and wind have eroded ancient surface structures, while earthquake and volcanic activity have steadily reshaped its surface. But other planets, and their orbiting moons, may have preserved their original features, thus affording an opportunity to gain insights into planetary evolution.
The concept of evolution has transformed the older view of nature, just as it did our view of man when it was earlier applied to illumine his social, ethical and religious life. For evolution is just an attempt to explain the world by showing the relations between things as parts of a single living process. |
