How are the concepts of microevolution and macroevolution linked?
Homework Answers
Microevolution changes which are observed lead to large macroevolution changes which are never observed.

5. Using the following evolutionary concepts (speciation, macroevolution, microevolution, gene flow,genetic drift, and natural selection), represent your idea of how these evolutionary concepts are related to another. Use lines to connect and show the relationship between concepts. Write a word or short phrase by each line to specify the relationship between cocnepts.

5. Differentiate between the processes and results of microevolution and macroevolution, and explain how these contribute to speciation. • Explain why individuals do not evolve? At what level does evolution occur? • What are gene pools? Describe microevolution. • What is macroevolution including speciation? What are novel features? 6. Relate the geologic history of the planet to evolutionary history, including mass extinctions and subsequent diversification. • What is the role of mass extinctions and diversification in macroevolution? • How does...

Biology question DNA part 2 6. Which is the difference between microevolution and macroevolution? Select one: a. microevolution affects bacteria and macroevolution affects larger organisms. b. microevolution happens slowly and macroevolution happens quickly. c. microevolution affects up to 100 base pairs and macroevolution affects chromosomes. d. microevolutionary changes are small, and macroevolutionary changes are large. 7. Darwin bred pigeons to have particular traits. Today people breed dogs, cats, horses, and other animals for the same reason. These activities illustrate: Select...

PRER TEACHING QUESTIONS Microevolution and Macroevolution (Chapters 16 and 17 and Lecture Outline) 1. What is the definition of evolution? Explain this in terms of alloles and gene pools. Describe each of the 4 causes of microevolution. What is the significance of mutations to evolution? Why is natural selection the most well-known" cause? 2. What is the biological species concept? Why is this important for our understanding of speciation? What are some of flaws with this definition? What are the...

24. Many creationists will allow that microevolution (for example, changing gene frequencies in a population) has occurred, and will even acknowledge that species adapt to different environments. However, they deny that macroevolution (they define it as the evolution of new "kinds") is supported by evidence. Explain how they are mistaken. How might you help your creationist friend better grasp how modern scientists consider micro- versus macroevolution? (4 points)

4. Systematics and Evolution (35 pts) Briefly describe the distinction between each pair of concepts: D. Biological vs. Paleontological Species Concept E. Genetic Drift vs. Natural Selection F. Cladogenesis vs Anagenesis G. Microevolution vs. Macroevolution

Some individuals agree that microevolution occurs (e g, shifts in allele frequency in a population across generations), but reject that macroevolution occurs, claiming that microevolution cannot create new "kinds" of organisms. For example, some will state that land animals cannot become animals that live exclusively in water (ie., whales). What evidence counters this claim? Note the key word in this question is "evidence". The question is not asking for verbal arguments against the claim, such as pointing out perceived flaws...

1. A major goal in macroevolution is to elucidate the causes of phenotypic trends. Describe at least one type of phenotypic pattern examined in the fossil record (note: this could be some pattern related to the average morphology over time or the variation over time). 2. The neo-Darwinian paradigm is often described as having three pillars: 1: natural selection operates at the individual level, 2: natural selection is the creative force in evolution (generates adaptations), 3: microevolution + time results...

(1) Explain the specific role of homeotic genes in controlling animal development; what specific aspect of development is controlled by homeotic genes, and how do they achieve this? (5 pts) (ii) Explain why a mutation to a homeotic gene can be an important macroevolutionary event. Your response should include a clear discussion of what macroevolution means and the type of evolutionary change associated with macroevolution (as opposed to microevolution), and why mutations to homeotic genes can result in macroevolution. (6...

5. Which of the following statements is true about the theory of evolution? The focus of the theory of evolution is to explain the origins of life. According to the theory of evolution, life evolved entirely randomly. The focus of the theory of evolution is to explain how life diversified from the first living cells. According the theory of evolution, only the strongest and toughest can survive. 6. Which of the following best explains our current understanding of microevolution? Neither...
