Biology 242 – Genomes & Evolution Fall 2017 Biology 242 – Genomes & Evolution Instructor: Dr. Terry Bird Office: Shiley Center for Science and Technology 432 Laboratory: Shiley Center for Science and Technology 474 Phone #: (619) 260-4671 email: [email protected] Office hours: Mon, Tues & Wed 1:30-2:30pm, Thurs 12:30-2:30pm or by appointment Text: Campbell Biology (11th Edition) (Mastering Biology) Inquiry in Action: Interpreting Scientific Papers, Buskirk & Gillen A Student Handbook for Writing Biology, 4th ed., Karin Knisely Course description This one-semester course for biology majors provides an introduction to the mechanisms and results of information flow through organisms and their lineages. Lecture topics will include the nature, expression, and change of hereditary information in DNA, the mechanisms of evolution, and the origins and relationships of major groups of organisms. The laboratory (Bio 242L) must be taken concurrently and will include inquiry into the genetic basis of evolutionary change, and testing of hypotheses of adaptation. Bio 242 and Bio 242L constitute half of the year of introductory biology. Bio 240 and 240L, Bioenergetics and Systems, should be taken the semester before or after Bio 242. This introductory series meets the general biology requirements of the biology major and health science professional programs, as well as the Core requirement for Scientific and Technological Inquiry. Students in majors other than the sciences should consider taking designated biology courses below the 200-level to fulfill this Core requirement. Course Learning Outcomes At the end of the semester a student who takes both Bio 242 lecture and lab should be able to: 1. Design and conduct an experimental and/or observational investigation to generate scientific knowledge. 2. Analyze data using methods appropriate to Biology in order to make valid and reliable interpretations. 3. Describe how information flows through cells, organisms, and entire populations; and how it contributes to the evolution of diverse organisms. 4. Identify and use appropriate and sufficient scientific evidence to evaluate claims and explanations about the natural world. 5. Define the role innovation plays in biology and articulate how biology fosters innovation toward societal change. Consider the role diverse perspectives play toward the creative and critical thinking necessary to biology. Fall 2017 Grading There are two midterm exams, each worth 100 points; there is one final worth 150 points. Note that all examinations, including midterms, are cumulative.

  • Microevolution and the Genetics of Populations ​ ​ Microevolution Refers to Varieties Within a Given Type
    Chapter 8: Evolution Lesson 8.3: Microevolution and the Genetics of Populations ​ ​ Microevolution refers to varieties within a given type. Change happens within a group, but the descendant is clearly of the same type as the ancestor. This might better be called variation, or adaptation, but the changes are "horizontal" in effect, not "vertical." Such changes might be accomplished by "natural selection," in which a trait ​ ​ ​ ​ within the present variety is selected as the best for a given set of conditions, or accomplished by "artificial selection," such as when dog breeders produce a new breed of dog. Lesson Objectives ● Distinguish what is microevolution and how it affects changes in populations. ● Define gene pool, and explain how to calculate allele frequencies. ● State the Hardy-Weinberg theorem ● Identify the five forces of evolution. Vocabulary ● adaptive radiation ● gene pool ● migration ● allele frequency ● genetic drift ● mutation ● artificial selection ● Hardy-Weinberg theorem ● natural selection ● directional selection ● macroevolution ● population genetics ● disruptive selection ● microevolution ● stabilizing selection ● gene flow Introduction Darwin knew that heritable variations are needed for evolution to occur. However, he knew nothing about Mendel’s laws of genetics. Mendel’s laws were rediscovered in the early 1900s. Only then could scientists fully understand the process of evolution. Microevolution is how individual traits within a population change over time. In order for a population to change, some things must be assumed to be true. In other words, there must be some sort of process happening that causes microevolution. The five ways alleles within a population change over time are natural selection, migration (gene flow), mating, mutations, or genetic drift.

  • Adaptation, Natural Selection and Evolution Learning Intentions • Give the Meaning of the Term Mutation
    Adaptation, natural selection and evolution Learning Intentions • Give the meaning of the term mutation. • State that mutations may be neutral, confer an advantage or a disadvantage. • State that mutations are spontaneous and are the only source of new alleles. • Give two environmental factors which can increase the rate of mutation. • Give the meaning of the term adaptation. • Give examples of adaptations which allow a species to survive. • State that adaptation may be structural, physiological or behavioural. • Describe examples of behaviours which allow a species to survive. • State that variation within a population makes it possible for a population to evolve over time in response to changing conditions. • Describe natural selection/survival of the fittest. • Describe the process of speciation. Mutation • A mutation is a random change to the genetic material of an organism • Mutations are rare, random and spontaneous • Mutations can alter the phenotype or functioning of the organism. • Mutations which occur in sex cells are inherited by offspring, they are the only source of new alleles, and can alter the phenotype or functioning of the organism. Types of Mutation • Mutations can be neutral, an advantage or a disadvantage • Neutral – these have no effect on the organism • Confer an advantage – for example the peppered moth mutation which made moths dark in colour – this allowed them to be camouflaged in industrial areas with soot covering trees • Confer a disadvantage – for example a gene mutation in chromosome 7 in humans leads to cystic fibrosis Moths…how many can you see? Mutagenic Agents • The rate of mutations can be artificially increased by environmental factors such as: – Radiation such as X-rays, UV light, gamma rays – Chemicals like colchicine, mustard gas and benzene.

Chapter 23: Population Genetics (Microevolution) Microevolution is a change in allele frequencies or genotype frequencies in a population over time Genetic equilibrium in populations: the Hardy-Weinberg theorem Microevolution is deviation from Hardy- Weinberg equilibrium Genetic variation must exist for natural selection to occur . Microevolution is a change in allele frequencies or genotype frequencies in a population over time population – a localized group of individuals capable of interbreeding and producing fertile offspring, and that are more or less isolated from other such groups gene pool – all alleles present in a population at a given time phenotype frequency – proportion of a population with a given phenotype genotype frequency – proportion of a population with a given genotype allele frequency – proportion of a specific allele in a population . Microevolution is a change in allele frequencies or genotype frequencies in a population over time allele frequency – proportion of a specific allele in a population diploid individuals have two alleles for each gene if you know genotype frequencies, it is easy to calculate allele frequencies example: population (1000) = genotypes AA (490) + Aa (420) + aa (90) allele number (2000) = A (490x2 + 420) + a (420 + 90x2) = A (1400) + a (600) freq[A] = 1400/2000 = 0.70 freq[a] = 600/2000 = 0.30 note that the sum of all allele frequencies is 1.0 (sum rule of probability) .

  • Science, Evolution, and Creationism: Brochure
    Why Is Evolution Important? The discovery and understanding of the processes of evolution represent one of the most powerful achievements in the history of science. Evolution successfully explains the diversity of life on Earth and has been confirmed repeatedly through observation and experiment in a broad spectrum of scientific disciplines. Evolutionary science provides the foundation for modern biology. It has opened the door to entirely new types of medical, agricultural, and environmental research, and has led to the devel- opment of technologies that can help prevent and combat disease. Regrettably, effective science education in our schools is being undermined by efforts to introduce non-scientific concepts about evolution into science classrooms. How Science Works The study of evolution provides an excellent example of how scientists go about their work. They observe nature and ask testable questions about the natural world, test those questions through experiment and new observations, and construct explanations of evolution based on evidence. As scientists gather new results and findings, they continue to refine their ideas. Explanations are altered or sometimes rejected when compelling contradictory evidence comes to light. Some scientific explanations are so well established that no new evidence is likely to alter them. The explanation becomes a scientific theory. In everyday language a theory means a hunch or speculation. Not so in science. In science, the word theory refers to a comprehensive explanation of an important feature of nature that is supported by many facts gathered over time. Theories also allow scientists to make predictions about as yet unobserved phenomena. A good example is the theory of gravity.

  • The Scientific Controversy Over Whether Microevolution Can Account for Macroevolution
    SUMMARY: The Scientific Controversy Over Whether Microevolution Can Account For Macroevolution © Center for Science and Culture/Discovery Institute, 1511 Third Avenue, Suite 808, Seattle, WA 98101 When Charles Darwin published The Origin of Species in 1859, it was already known that existing species can change over time. This is the basis of artificial breeding, which had been practiced for thousands of years. Darwin and his contemporaries were also familiar enough with the fossil record to know that major changes in living things had occurred over geological time. Darwin's theory was that a process analogous to artificial breeding also occurs in nature; he called that process natural selection. Darwin's theory was also that changes in existing species due primarily to natural selection could, if given enough time, produce the major changes we see in the fossil record. After Darwin, the first phenomenon (changes within an existing species or gene pool) was named "microevolution." There is abundant evidence that changes can occur within existing species, both domestic and wild, so microevolution is uncontroversial. The second phenomenon (large-scale changes over geological time) was named "macroevolution," and Darwin's theory that the processes of the former can account for the latter was controversial right from the start. Many biologists during and after Darwin's lifetime have questioned whether the natural counterpart of domestic breeding could do what domestic breeding has never done -- namely, produce new species, organs, and body plans. In the first few decades of the twentieth century, skepticism over this aspect of evolution was so strong that Darwin's theory went into eclipse.
