Zoology Lecture 1
Science of Zoology and Evolution of Animal Diversity
| Question | Answer |
|---|---|
| Define Zoology | The biological study of animals |
| Scientific method process and approach | Observe, Question, Hypothesis Formation, Experimental Design, Test Hypothesis, Collect Date, Analyze Data, Publication |
| Define Paradigm | Major concepts that guide extensive research |
| Define Scientific Revolution | Refutement and replacement of Paradigm |
| Two major paradigm that guide zoological research | Darwin's Theory of Evolution / Chromosomal Theory of Inheritance |
| Darwin's Theory of Evolution | Compacted mutually theories smuched into one than leads to Drawinism 5 major theories and these theories MUST be followed |
| The Chromosomal Theory of Inheritance | |
| Experimental Science | Explain the immediate or proximate causes the functioning of biological system at a time and place |
| Evolutionary Sciences | Seek to answer ultimate causes by using a similar pattern method instead of experimentation |
| Charles Linnaeus | He developed the Taxonomy system and Binomial Nomenclature (naming of the species) and classification system. "Father of modern Taxonomy." |
| Two word termology | Genus and Species. Genus captailized. Underlined or itallic. Ex. H. spaiens |
| James Hutton | Developed Uniformitarianism (physical factors that operate history) |
| Charles Lyell | Helped Hutton. Principles of Geology. |
| Lamarck | First one to formalized the idea on evolution based on inheritance |
| Thomas Malthus | British scholar and economist. Focus human population growth |
| What was is Malthus theory? | Population decreases because not enough recsources |
| Charles Darwin | British Naturalist. Went on the Beagle to explore evolution. |
| Gregor Mendal | Experimented on peas. Work was ignored until it was the key ingrediant to evolution. Father of genetics |
| What did Darwin not know? | Genetics |
| What are the 5 theories of Darwinism? | - |
| 1. | Perpetual Change |
| 2. | Common Descent |
| 3. | Multiplication of the Species |
| 4. | Gradualism |
| 5. | Natural Selection |
| Perpetual Change | The world and all that inhabit it is ever changing |
| Common Descent | All living organisms are from a common ancestor |
| Phylogeney | Evolutionary Tree |
| Multiplication of the Species | Shows the growth of a species. 1 species = 2 descendant species |
| Gradualism | Small differences is the raw material of an organisms evolution. Not massive events. |
| Adaptive Radiation | Adapting to a biome |
| Alleles | Code for a trait. Form of a gene |
| Neo-Darwinism | Putting together genetic and other ideas (Natural Selection) |
| Natural Selection | Darwin's mechanism of evolution. Organisms adapt to environment to surive |
| Darwin's Model of Evolution: Observations and Inferences | Name all |
| O1 | High Reproductive Potential |
| O2 | Natural populations remain relatively constant in size |
| O3 | Resources are limited in nature |
| O3 Inferences | Competition for resources |
| O4 | Considerable variation within populations |
| O5 | Some variation is heritable (offspring looks like parents) |
| O5 Inferences | Differential survival and reproduction |
| O5 Inferences | Over many generations NS produces new adaptations and species |
| Phenotype | Physical traits |
| Genotype | Genetic make-up |
| Neo-Darwinism | Darwin theories modified by incorporating the Chromosomal Theory of Inheritance |
| Chromosomal Theory of Inheritance | Chromosomes take certain/specific positions in the gene |
| Microevolution and Macroevolution differ in what? | The scale of inquiry |
| Microevolution | Evolutionary change in alleles form and frequencies within a population |
| Macroevolution | Grand evolutionary transitions |
| What criteria must the Hardy-Weinberg equilibrium to exist? | Large population with random mating / Diploids / No migration / No emigration / Balanced mutation & migration / No natural selection |
| Study Hard-Weinberg equation | |
| Define Gene pool | All alleles in all genes exist in a population |
| Define Polymorphism | Different allelic forms of gene constitute |
| Define Allelic Frequency | Frequency of a specific allele in a population |
| Genetic Drift | The lose of genes randomly without chance |
| Bottleneck | Leads to speciation / large reduction in population which increases the occurance of genetic drift / associates with the formtation of founder effect |
| Founder Effect | Species re in a new area and form a new structure |
| Ex. of Bottleneck | Elephant Seals and Cheetahs |
| Identify and define Positive Assortative Mating | Individuals mate with each other of the same gene pool / Increases Homozygosity / Decreases Heterozygosity / Does not change allelic frequency |
| Identify and define Inbreeding | Look at slide Page 20 |
| Identify and define Migration | Look at slide Page 20 |
| Identify and define stabilizing, disruptive, and directional selection | Look at slide Page 21 |
