Bio 1610 Test 6
Biosytematics, Evolutionary Theory and Evolutionary History
| Question | Answer |
|---|---|
| Described many plants according to the "creators Plan" | John Ray |
| The Father of Taxonomy. Published Systema Naturae. Binomial System | Caroleus Linnaeus |
| Name System based on utility | Ancient Taxonomy |
| Name System based on one or very few attributes. Very Rarely used. Canary and Banana are yellow. | Artificial Taxonomy |
| Name system based on as many attributes as possible. Physical Characteristics, not behavior | Natural Taxonomy. |
| Characteristics w/ a common evolutionary history | Phylogenics |
| Classifications according to order in time | Cladistics |
| method for identifying organisms, made of couplet and leads | Dichotomous Keys |
| Group of two leads | Couplets |
| Two contrasting statments | Leads |
| Example - ophyta | Division |
| Example -opsida | Class |
| Example -ales | order |
| Example - aceae | Family |
| Example - Sequoiadendron | Genus |
| Example - giganteum | Specific epithet |
| Example Felis Concolor | Species |
| Father of speculative science. Life arose through water. "study nature through nature" | Thales |
| Pupil of Thales "simple things precede complex things" | Anaximander |
| The Father of Biology. Published Scala Naturae. The great chain of being- everything tries to move towards perfection | Aristotle |
| Belief that the world is 6000 years old, and shaped by sudden catastrophic events | Catastrophism |
| The Father of historical geology. Published Theory of the Earth | James Hutton |
| 1st of Hutton's Principles Belief that the earth formed gradually over time | Uniformitarianism |
| 2nd of Hutton's principles older geologic strati buried, newest on top | Principle of superposition |
| 3rd of Hutton's principles. Layers that cross cut other layers are newer than the ones they penetrate | Principle of Cross-cutting Relationships |
| Hutton's 4th principle- 6000 years could not have been the amount of time required to form the earth | Deep Time |
| Formed the idea that individuals evolve to suit environment...Lamarckianism | Lamarck |
| Essays on the Principles of Populations. External Controls on population, competition for resources limits pop. size | Malthus |
| Inspired by Malthus' book, lived in SE Asia, observed natural selection. Sent unpublished paper to Darwin | Wallace |
| Copublished Evolution by Natural Selection w/ Wallace. The Origin of Species. | Darwin |
| Human beings breed traits in organisms that we desire . Variation under domestic conditions, faster than evolution | Artificial Selection |
| As many traits as possible, chosen by nature. Variation under natural conditions. Evolution | Natural Selection |
| natural differences. Mutation accounts for most of this | Variation |
| how fitness is acquired. Fitness changes according to environment | Adaptation. |
| A single supercontinent 250 mya | Pangaea |
| Majority of the Geologic timescale | Precambrian |
| Ran El. Currents through CH4, NH3, H2, and H20 Vapor, and amino acids formed | Miller and Urey |
| Comparative anatomy | Haekel |
| Adaptive Radiation. Structures start from same plant, become diff. based on env. | Homologous Structures |
| Two vastly diff. organisms look similary b/c of environmental similarities | Convergent Evolution |
| Structures that have lost some or all of their functions. Ex. Legs in Whales, tail bones, appendix, third molars, nipples on males in humans) | Vestigial Structures |
| Genes that remain in genome, but rarely or never are activated. Ex. teeth in chicken, tail in humans, extra nipples. | Atavistic traits |
| Barrier to interbreeding of species. Egg and sperm never meet | Pre-zygotic |
| Barrier to especiation. Results after egg and sperm join. Ex. limited offspring viability, reduced fertility | Post-zygotic |
| males and females look different, females responsible for selection | Sexual dimorphism |
| can produce viable offspring | Biological species |
| evolution of new species | Speciation |
| Formed as a result of geographic isolation | Allopatric speciation |
| Formed while living in same environment | Sympatric speciation |
| Requirements of this mathmatical function include- Large Population size, No genetic drift, No mutations, Completely Random mating (no preferred genes), No Natural selection | Hardy- Weinberg |
| p+q=1 p= dominant q = recessive | allelic frequencies |
