Some biologists claim that most evolutionary change takes place as a result of a series of very small changes . , June . 5, . 2015. HOMEWORK: . Evolution . Test June . 10,11,15,16. OBJECTIVE:. . I will be able to . identify two patterns that describe the rate of evolution using evidence for . evolution. DO . NOW: . PUNCTUATED EQUILIBRIUM OR EVOLUTION?: 1PUNCTUATED EQUILIBRIUM OR EVOLUTION?:1element that would identify changes over time. Even assuming that fully established enduring 2manifestations of rivalries, EVOLUTION #1 (Group 3). Strawberry Frogs Forever. Participants: Lin Xiang. Ingo . Schlupp. Tiffany Roberts. Anne . Grippo. Jerry Farris. Facilitators: Brooke . I. Species Definitions. Species represent the boundary for the spread of alleles . and define the unit in which the modes of evolution operate. Biological Species Concept. Individuals belong to the same species if they can interbreed with each other. 3 Mechanisms for selection and an introduction to . Hardy-Weinberg. Lyell’s Influence. In attempt to . explain the past in terms of present day processes. , Darwin went to local farmers and animal breeders and observed…. Section 1 Vocabulary Pretest. Population Genetics. Microevolution. Gene Pool. Allele Frequency. Phenotype Frequency. Total genetic information in a population. Portion of gene copies of a given allele. Sympatric Speciation. Sympatric Speciation occurs . without. geographic isolation, thus it occurs at a local level. . There is something within the environment that keeps a single species separated into two or more distinct groups.. Gene Pool. All the alleles present in the reproducing members of a population at a given time.. The gene pool is constantly changing. Mutations add new alleles to the population. Immigration also adds new alleles; changes the allele frequency. I. Species Definitions. Species represent the boundary for the spread of alleles . and define the unit in which the modes of evolution operate. Biological Species Concept. Individuals belong to the same species if they can interbreed with each other. Chapter 11 Biology Textbook. KEY CONCEPT . Hardy-Weinberg equilibrium provides a framework for understanding how populations evolve.. . Hardy-Weinberg equilibrium describes populations that are not evolving. . They do this through a series of . proposed explanations for observed phenomena. called . hypotheses. . . These hypotheses are then tested over a period of years to determine if they are supported by facts or if they need to be revised..
