theory of evolutoin
| Question | Answer |
|---|---|
| when did explorers travel the globe? | explorers traveled the globe in the 18th and 19th centuries |
| who were the many new species discovered by? | naturalists |
| were the new soecies similar? | yes |
| what question did the naturalist ask? | if the species were related |
| who are the 2 scientists? | Alfred Russell Wallace and Charles Darwin |
| who wrote a book? | Darwin |
| what was it called? | On the Origin of Species |
| who explained there theory in a book? | Darwin |
| when was the book published? | 1859 |
| how do we know this theory? | theory of evolution by natural selection |
| how many point does it have? | 5 |
| what is 1 of 5? | Organisms produce similar organisms -- a cat produces a cat, an oak tree produces another oak tree, and a bird produces a bird. |
| 2 of 5 | Often, organisms produce more offspring than can survive in any given environment. |
| 3 of 5 | In any population, individuals vary with respect to any given trait, such as height, color, or body shape. We now know that mutations and genetic recombination in DNA cause these variations (Darwin did not). |
| 3 of 5 extended | These variations can be passed on to the next generation. |
| 4 of 5 | Individuals with variations that make them best suited to their environment will survive, while those with variations that are ill-suited to the environment will die out. |
| 4 of 5 | Only those organisms that survive will pass their favorable traits on to their offspring. This process is natural selection. |
| 5 of 5 | Given sufficient time (Darwin thought a long time), natural selection will accumulate these favorable traits. The species will evolve from one form to another as environmental conditions change. |
| what did darwin do that no other scientist would do? | showing how evolution could happen. |
| what did the geographical evidence site? | that the earth was very old. |
| what did the fossils show? | change over time. |
| what did the embryos show? | that the diverse organisms resembled each other. |
| most prganism share what? | common body plan. |
| since DNA technology has become more advanced, what has mankind been able to do? | we have changed the genetic make-up of populations and created new organisms, such as bacteria that produce human insulin. |
