BigIdea Investigation 2 S25 Evolution 1 INVESTIGATION 2 MATHEMATICAL MODELING: HARDY-WEINBERG* How can mathematical models be used to investigate the relationship between allele frequencies in populations of organisms and evolutionary change? ? BACKGROUND Evolution occurs in populations of organisms and involves variation in the population, heredity, and di!erential survival. One way to study evolution is to study how the frequency of alleles in a population changes from generation to generation. In other words, you can ask What are the inheritance patterns of alleles, not just from two parental organisms, but also in a population? You can then explore how allele frequencies change in populations and how these changes might predict what will happen to a population in

Hardy–Weinberg principle

CHAPTER 23 THE EVOLUTION OF POPULATIONS OUTLINE I. Population Genetics A. The modern evolutionary synthesis integrated Darwinian selection and Mendelian inheritance B. The genetic structure of a population is defined by its allele and genotype frequencies C. The Hardy-Weinberg theorem describes a nonevolving population II. Causes of Microevolution A. Microevolution is a generation-to-generation change in a population's allele or genotype frequencies B. The five causes of microevolution are genetic drift, gene flow, mutation, nonrandom mating, and natural selection III. Genetic Variation, the Substrate for Natural Selection A. Genetic variation occurs within and between populations B. Mutation and sexual recombination generate genetic variation

On the Origin of Species

Chapter 22: Descent with Modification: Darwinian View of Life?Lecture Outline Overview: Darwin Introduces a Revolutionary Theory On November 24, 1859, Charles Darwin published On the Origin of Species by Means of Natural Selection. Darwin?s book drew a cohesive picture of life by connecting what had once seemed a bewildering array of unrelated facts. Darwin made two major points in The Origin of Species: Today?s organisms descended from ancestral species that were different from modern species. Natural selection provided a mechanism for this evolutionary change. The basic idea of natural selection is that a population can change over time if individuals that possess certain heritable traits leave more offspring than other individuals.

Natural Selection: The biological process by which variations that enhance a populations ability to survive in a particular environment become dominant in a species over very long periods and lead to evolution of a new species. Africa was thought of the origin of all humans because of the large populations of apes even though there was no evidence.

Chapter 13 Meiosis and Sexual Life Cycles Overview: Hereditary Similarity and Variation Living organisms are distinguished by their ability to reproduce their own kind Heredity is the transmission of traits from one generation to the next Variation shows that offspring differ in appearance from parents and siblings Genetics is the scientific study of heredity and variation Concept 13.1: Offspring acquire genes from parents by inheriting chromosomes In a literal sense, children do not inherit particular physical traits from their parents It is genes that are actually inherited Inheritance of Genes Genes are the units of heredity Genes are segments of DNA Each gene has a specific locus on a certain chromosome One set of chromosomes is inherited from each parent

Eugenics ? Traits Studied Charles Davenport was the director of three institutions based at Cold Spring Harbor ? the ERO, the Biological Laboratory, and the Carnegie Institute of Washington?s Station for Experimental Evolution He noted in his 1909 Annual Report that the inability to conduct controlled experiments ruled out human genetics as a suitable topic for the Station for Experimental Evolution He and his wife published 4 papers between 1907 and 1910 that applied Mendelian principles to the human inheritance of eye color, hair color, hair texture and pigmentation The paper on skin pigmentation made the first reference to polygenic inheritance ? a trait influenced by two or more genes The eye color paper relied on data supplied by ?school principals and other friends?
