Solved in 2 steps
- 1. How do we measure and define evolution? 2. Evolution occurs: 1. at the level of the individual. 2. in traits. 3. in a single generation. 4. only at the phenotypic level. 3. The only source of entirely new genetic material is: 1. natural selection. 2. mutation. 3. recombination. 4. genetic drift. 4. Which of the following is not a key component of natural selection? 1. Traits for strength and vitality are favored over other traits. 2. Random variation exists for every trait in a population. 3. There will always be competition for resources. 4. Those with advantageous traits will outreproduce others. 5. The founder effect is a specific type of: 1. gene flow. 2. meiosis. 3. genetic drift. 4. mutation. 6. When a substantial amount of genetic variation is lost, we call it a: 1. genetic die-off. 2. gene flow. 3. genetic bottleneck. 4. gene dam. 7. When two previously isolated populations begin interbreeding and exchanging genes, we call it: 1. genetic drift. 2. founder effect. 3. incest.…In Darwin's theory of natural selection, which of the following is a source of evolution: a.Individuals who do not vary from their progenitors. b.Intelligent and purposeful design. c.Individuals with random mutations who are able to reproduce. d.Individuals with random mutations who die without reproducing.What is the theory of Darwinism?What did Darwin propose as the mechanism of evolution?
- Describe the two principles of evolution that Charles Darwin proposed: 1) Common Descent with Modification and 2) Natural Selection. Give examples of eachThe theory of evolution by Darwin is a composite theory, i.e. it has five component theories: 1. Evolution as such is the simple proposition that the characteristics of lineages of organisms change over time 2. Common descent is a radically different view of evolution than the scheme Lamarck proposed. Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. 3. Gradualism – Darwin’s proposition that the differences between even radically different organisms have evolved incrementally, by small steps through intermediate forms. The alternative to this theory, as discussed in later sections, is saltation with great reference to large differences that are believed to have evolved by leaps without intermediates. 4. Populational change – Darwin’s thesis that evolution occurs by changes in the proportions of individuals within a population that have different inherited characteristics. 5. Natural selection – Darwin’s…The theory of evolution by Darwin is a composite theory, i.e. it has five component theories: 1.
