| two species that become more and more dissimilar overtime are called what | divergion |
| "survival of the fittest" means | natural selection |
| darwin was influenced by who's work on populatiopn | malthus |

| theory similar to darqins but darwin beat him to it? | wallace |
| scientist that established the field of paleontology | george cuvier |
| what level of classification is slightyl more specific than order | family |
| what period is after the permian | triassic period |
| large provkayyotic cells engulfed prokaryotes which evolved into what | mitochondria called endysym,biotic |
| who is Carolus Linnaeus (1707-1778) | Swedish Father of taxonomy-classification Found order in the diversity of life Adopted a system of grouping species into categoriesRanked the categories into a hierarchyclassification hierarchy- domain- kingdom- phylum- class-order -family-genus- species |
| what is Binomial Nomenclature | Developed by Linneaus Two names for each organism Genus species |
| who is Jean Baptiste Lamarck1744-1829 | Was in charge of the invertebrate collection at the Natural History Museum in Paris Compared modern species to fossils Envisioned a ladder of organisms from unicellular to plants and animals |
| what is Lamarck’s Mechanism for Evolution | Use and Disuse: body organs used a lot to cope with environment become stronger and larger and those not use deteriorate Inheritance of Acquired Characteristics: the changes an organism acquired during lifetime could be passed to its offspring |
| acquired characteristics | Lamarck |
| who established paleontology, the study of fossils | George Cuvier |
| who said the theory of geological gradualism, profound changes to Earth over time | James Hutton |
| who said Earth is ancient and that slow and gradual changes over time took place on the Earth; mountains build and erode | Charles Lyell |
| who said populations continue to grow and are held in check by starvation and disease | Rev Thomas Mathus |
| what did thomas malthus write | Essay on the Principle of Population |
| what did charles darwin do | Field research helped frame his view of life |
| what did charles darwin write and what did it say | Wrote on the origin of species and natural selection Published The Origin of Species in 1859 Mechanism for evolution:1. Descent with Modification 2. Natural Selection and Adaptation |
| what is natural selection and adaptation | All species have great potential to form large populationsPopulations, though, tend to remain stable in size, except for seasonal fluctuations There is a struggle for existence among individuals of the population Individuals vary in a population Those ind |
| what did Alfred Russell Wallace do | Developed a theory of natural selection very similar to Darwin Specimen collector in East Indies Darwin published first |
| where did darwin present his paper | Linnaean Society in London |
| what is the unit of evolution | The population: a group of interbreeding individuals belonging to a particular species and sharing a common geographic area Evolution can only be measured as change in relative proportions of variations in a population over several generations |
| what evidence for evolution is there | Biogeography: the geographical distribution of species Fossil Record Comparative Anatomy Vestigial Structures Comparative Embryology Molecular Biology |
| evidence for human evolution | No apparent function Resemble structures found in their presumed ancestor Muscles for wiggling ears in humans Appendix in humans Molars in humans (viligrant structures) |
| what is COEVOLUTION | The change of two or more species in close association with each other. The pattern and speed of evolutionary change result from the changing requirements of the environment. Predators and Prey Flowers and Pollinators Hosts and Parasites |
| what is Convergent Evolution | Organisms appear to be similar but are not closely related by a common ancestor. Typical of analogous structures Organisms evolve similar traits as they adapt to similar environments. |
| what is Divergent Evolution | Two RELATED populations or species become more and more dissimilar. In response to differing environments or habitats. |
| what were darwins 2 claims | 1.Modern species evolved from ancestral forms. Descent with modifications 2.The mechanism for evolution is natural selection |
