| Question | Answer |
|---|---|
| Published On the Origin of Species by Means of Natural Selection in 1859 | Charles Darwin |
| What are the two points made in The Origin of Species | Today's organisms are descended from ancestral species (DESCENT WITH MODIFICATION) and NATURAL SELECTION provided a mechanism for evolutionary change in populations |
| The dominant philosophy in the 1700's | Natural theology |
| A hierarchal classification system developed by Carolus Linnaeus | Taxonomy |
| Influenced Darwin's views | Fossils |
| Organisms mineralized in sedimentary rocks | Fossils |
| He helped develop paleontology and believed in catastrophism | Georges Cuvier |
| James Hutton proposed this theory that earth must be older than 6000 years | Gradualism |
| Charles Lyell proposed this theory that given enough time, big changes result from subtle processes | Uniformitarianism |
| Published a theory of evolution in 1809 | Jean Baptiste Lamarck |
| Jean Baptiste Lamarck's mechanism of evolution included the concepts of | use and disuse of parts and of inheritance of acquired characteristics |
| The process where humans modify other species by selecting and breeding individuals with desired traits | Artificial selection |
| Darwin's first three observations of nature | 1. Members of a population often vary greatly in their traits 2. Traits are inherited from parents to offspring 3. All species are capable of producing more offspring than the environment can support |
| Darwin's fourth observation of nature | 4. Owing to lack of food or other resources, many of these offspring do not survive |
| Darwin's first inference based on his observations | 1. Individuals whose inherited traits give them a higher probability of surviving and reproducing in a given environment tend to leave more offspring than other individuals |
| Darwin's second inference based on his observations | 2. This unequal ability of individuals to survive and reproduce will lead to the accumulations of favorable traits in the population over generations |
| _____do not evolve, _____ evolve over time | individuals, populations |
| The effect of differential predation on guppy populations and the evolution of drug resistant HIV are examples of _______ | natural selection |
| What happened with Endler's guppy experiment | When he transferred bright guppies to a pool with many predators over time the pop. became less bright. When he transferred drab guppies to a pool with few predators over time the pop. became more bright. |
| 4.6 billion years ago | the solar system/earth formed |
| 3.9 billion years ago | the oldest rocks we have on the planet formed because this is when the earth was cool enough to form rocks |
| 3.5 billion years ago | first life (prokaryotes=cyanobacteria, found in structures called stromatolites, cyanobacteria is sometimes called blue-green algae but they aren't algae because algae are eukaryotes) |
| 2.2-2.7 billion years ago | oxygen revolution changed the earth |
| 2.1 billion years ago | first eukaryotes (single-celled protists) |
| 1.2 billion years ago | 1st multicellular eukaryotes (algae) |
| 600-750 million years ago | snowball earth |
| 544 million years ago | 1st multicellular animals- metazoans (sponges, jellyfish, worms) |
| What forms ozone | oxygen (O2+O2=O3) |
| Evidence for evolution | 1. Direct observation 2. Fossil record 3. Homologies 4. Convergent evolution 4. Biogeography |
| Similarity resulting from common ancestry | Homology. The more homologies shared the closer in relation. Hair is homologous to mammals |
| Anatomical resemblances that represent variations on a structural theme present in a common ancestor | Homologous structures |
| _____existing structures produces imperfections | "retrofitting" (back and knee problems are common in humans) |
| Structures with little or no importance, derived from important ancestral structures. Examples are hind legs in whales or remnants of hind limbs that look like claws in ball pythons | Vestigial organs |
| The Darwinian concept that are hypotheses about the relationships among groups. Can be made using different types of data such as anatomical and DNA sequence data | Evolutionary tree |
| Similar features in distantly related groups that arise when groups independently adapt to similar environments in similar ways | Analogous traits |
| The evolution of analogous features in distantly related groups. Does not provide information about ancestry | Convergent evolution |
| The geographic distribution of species | Biogeography |
| Islands have many ____ species that are often closely related to species on the nearest mainland or island; many species of plants and animals that are found nowhere else in the world | Endemic |
| Earth's continents were formerly united in a single large continent called _____, but have since separated by _____ | Pangaea, continental drift |
| Siad factuality of evolution is beyond a reasonable doubt and that to reject evolution is to reject reason | Pope John Paul II Oct. 22, 1996 Pontifical Academy of Sciences |
| British "God has an inordinate fondness for beetles" | Haldane |
| layers | strata |
| Flood or drought came along and formed layers. Cuvier says that it wiped out species (didn't believe in evolution) | Catastrophism |
| Lyell and Hutton proposed similar theories | Gradualism and uniformitarianism |
| Giraffes stretching necks is an example of | Inheritance of acquired characteristics |
| Temperate and tropical plants of South America are more similar than Temperates in South America and Temperates in Europe | Regional similarity, noted by Darwin |
| Sent Darwin his manuscript in 1858 | Alfred Wallace |
| What Darwin was greatly influence by | Artificial selection |
