Introduction to Evolution Terminology You should be able to define and describe the Characteristics of the following terms processes individuals and concepts and either use them in a sentence or provide an example of each Evolution Microevolution Macroevolution Species Fitness Carolus J ean B aptiste Charles Darwin Descent with Variation Linnaeus Lamarck Modification Heritable Natural Adaptation Fossil Records Vertical Selection Transmission Speciation Biogeography Convergent ArtificialSelectiv Homology Evolution 6 Breeding Vestigial Traits Anatomical Developmental Molecular Gene Homology Homology Homology Review Questions Below are a series of questions that in addition to the PERQ for this unit will help you understand and review material found in this lecture Importantly you should be able to explain why the answer you have Chosen is the correct answer 1 The term natural selection is sometimes confused with the term evolution Discuss the meanings of these two terms Explain how the terms are different and how they are related to each other The theory of evolution is best described by Charles Darwin as descent with modification In other words populations evolve gradually over time from a common ancestor Keep in mind that there are two forms of evolution microevolution in which changes in a single gene occur over time as a result of mutation and macroevolution or the genesis of new species Natural selection acts on the individual to drive the evolutionary process by selecting for those traits that increase fitness an organism s ability to survive and reproduce The bird example discussed during lecture 3 is a prime example of this 2 The process of biological evolution a Is not supported by scientific evidence Results in a Change in the features of individuals in a population Takes place over the course of generations B and C are correct A B and C are correct 099quot 3 A species of crayfish that lives in caves produces eyestalks like its above ground relatives but no eyes Eyestalks in cave dwelling crayfish are thus An evolutionary error A dominant mutation Biogeographical evidence of evolution A vestigial trait Evidence that evolutionary theory may be incorrect 990599 4 Antibiotic resistant bacteria are becoming a major concern in the healthcare field Using what you know about the processes of natural selection and evolution describe howwhy these bacteria might develop a resistance to specific drugs such as Penicillin Antibiotic resistance often emerges as a mechanism for bacteria to evade drugs such as penicillin which would otherwise kill the bacteria This evolutionary process takes place gradually and is caused by a mutation in the bacteria s genome that confers antibiotic resistance 5 The only microevolutionary process that adds heritable changes to the gene pool total number of alleles genes of a population is a Fitness b Natural selection c Gene ow d Genetic drift e Mutation
