- Which of the following is not a component of evolution bynatural selection?a. Variation exists within a population.b. Organisms compete for resources.c. Individuals have different reproductive success.d. Organisms adapt due to environmental changes.e. Species are fixed.arrow_forwardAlfred Russel Wallace and Charles Darwin argued that evolution by means of natural selection involves all of the following steps except: a. variation is present in all species b. species can produce more offspring than the environment can sustain c. all individuals within a species have equal chances to improve their fitness d. those individuals that are more fit will survive and reproduce in the greatest numbers e. over time, the species will evolve as the more fit individuals replace the less fit individualsarrow_forwardWhat is meant by the following statement? "When mutation is random, natural selection is not." Mark all correct answers Group of answer choices A. A mutation is caused by changes in the environment. B. Natural selection can favor some mutations and not others. C.Mutations for advantageous traits are more likely to be passed on to the next generation. D.Selection can change depending on the environment.arrow_forward
- Which of the following is false regarding artificial selection? B. Artificial selection is responsible for creating new varieties of plants and animals D. Many if not most organisms created through artificial selection could not survive without humans E. None of the above---all are true statements A. Darwin's understanding of artificial selection helped him arrive at his theory of evolution by natural selection C. Artificial selection is caused through the process of selective breedingarrow_forwardWhich of the following best explains the role mutations play in natural selection?A. Most mutations are negative and result in the extinction of the entire speciesB. Mutations may appear for one or two generations, but they usually disappear quickly.C. If the environment changes, an existing organism develops a mutation that will help them to survive.D. Some mutations give individuals an advantage in their environment, allowing them to survive and reproduce.D is my answer is it correct?arrow_forwardDarwin’s finches are a noteworthy case study of evolution by natural selection because evidence suggests a. they are descendants of many different species that colonized the Galápagos. b. they radiated from a single species that colonized the Galápagos. c. they are more closely related to mainland species than to one another. d. None of the choices is correct.arrow_forward
- Which of Darwin's five 'theories' was something that he strongly emphasized but that we now think is a bit over emphasized on his part. Group of answer choices A. evolution has happened B. evolution is a process of change and splitting C. evolution is a very slow and gradual process D.all life has a common ancestor E.natural selection is the primary force causing evolutionarrow_forwardDarwin was not the first to propose a mechanism for evolution. Lamarck proposed “acquired inheritance” in which individuals inherit those traits acquired in the lifetime of their parents (e.g., long necks). Compare Lamark’s mechanism to Darwin’s mechanism for evolution (descent with modification). As part of your answer describe how each theory is similar to the other and how each is different? Finally, Lamarck’s theory can be easily shown to be unworkable (e.g., amputees don’t have babies that are amputees meaning babies don’t inherit the acquired trait). What makes Darwin’s theory workable when compared to Lamarck’s unworkable theory.arrow_forwardThe theory of evolution by Darwin is a composite theory, i.e. it has five component theories: 1. Evolution as such is the simple proposition that the characteristics of lineages of organisms change over time 2. Common descent is a radically different view of evolution than the scheme Lamarck proposed. Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. 3. Gradualism – Darwin’s proposition that the differences between even radically different organisms have evolved incrementally, by small steps through intermediate forms. The alternative to this theory, as discussed in later sections, is saltation with great reference to large differences that are believed to have evolved by leaps without intermediates. 4. Populational change – Darwin’s thesis that evolution occurs by changes in the proportions of individuals within a population that have different inherited characteristics. 5.
