Evоlutiоn is the cоre theory of biology, linking аll orgаnisms over time by а common bond of relatedness. The study of evolution is a complex, multi-disciplinary task. To understand how biologists think and explain the natural world, you must understand the theory of evolution. For each of the following, indicate if the statement is true by selecting "True" or selecting "False" in the dropdown. [a] a. Historians tell us that until the early 1800's most people, scientists included, accepted that the world was young and that species were created and not changed – a very reasonable understanding at the time. [b] b. Biogeographers tell us that organisms are not distributed upon the earth randomly, but seem to be adapted to the environment in which they exist. [c] c. Geologists tell us that the earth is very old, and that slow processes given enough time can make great changes. d. Evolutionary biologists refine and apply their understanding of Charles Darwin's idea of natural selection. Are the following elements of Darwin's process of natural selection stated correctly below? [d1] d1. Individual living things vary, and their variations can be heritable, that is they can be passed from generation to generation, from parent to offspring. [d2] d2. Living things have more young than can survive. [d3] d3. Living things with certain variations will do better in a specific environment, or said another way, will be better adapted to that environment. [d4] d4. Those that have variations which best adapt them to the environment will capture the most resources and mates and produce the most offspring. [d5] d5. Offspring who inherit the adaptive variation in general will become more numerous in that environment, so that over time many or all of that living thing may come to possess the variation. [e] e. Population biologists tell us that populations of a species, if they stop interbreeding, can change so much that they can no longer reproduce successfully, and thereby become separate species. [f] f. Evolution is referred to as a theory because scientists have little confidence in it. [g] g. The Theory of Evolution as we know it is a product of the work of only one person – Charles Darwin.
