- You have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity:arrow_forwardA major source of evidence for evolution is to be found in the comparative anatomy of organisms. Features that look different but have similar structural origin are calleda. homologous structures.b. analogous structures.c. vestigial structures.d. convergent structuresarrow_forwardWhich one of the following traits is not shared by most model species? A. High fecundity B. Short generation time C. Ease of maintaining populations in a lab environment D. Exhibit traits that are relevant to human biomedical science E. Developmental fate of each cell has been mapped from embryo to adultarrow_forward
- With regard to biological evolution, which of the following statements is incorrect? Explain why.A. During its lifetime, an animal evolves to become better adaptedto its environment.B. The process of biological evolution has produced species thatare better adapted to their environments.C. When an animal is better adapted to its environment, the process of natural selection makes it more likely that the animalwill reproduce.arrow_forwardSome advocates of the view that all organisms were created simultaneously by God argue that vestigial structures do not constitute evidence of evolution, because they show only that a divinely created structure can degenerate over time. According to this view, human tailbones are not evidence of evolution because they do not show that an adaptive improvement has occurred. Is this a valid argument?arrow_forwardDarwin's concept of evolution "the theory of decent with modification through variation and natural selection" can best be demonstrated by which of the following examples? a. A giraffe stretches his neck to reach higher branches. The exercise of stretching up strengthens the muscles in the giraffe's neck and legs. This ability to stretch is also seen in the giraffe's offspring. b. A monkey accidentally drops her fruit in the salty water of a bay. She recovers the fruit and eats it. She discovers the fruit is cleaner and tastes better after it has been in the salty water. She continues to wash the fruit in the bay before eating it. Her offspring see what she has done and also wash their fruit in the salty water. Soon, the whole population of monkeys is washing their fruit. c. Several turtles hatch from a clutch of eggs buried in the sand on a beach. One of the turtles is the color of the sand; the others are darker in color. The turtles scurry toward the water,…arrow_forward
- Which of the following is correct regarding the process ofevolutionary change?a. an adapted individual is the one that survives and passes on itsgenes to offspring.b. changes in phenotype are passed on by way of the genotype tothe next generation.c. organisms are able to bring about a change in their phenotype.d. evolution is striving toward particular traits.e. All of these are correct.arrow_forwardEvolution is based on which of the following concepts? (a) organisms share a common origin (b) over time, organisms have diverged from a common ancestor (c) an animals body parts can change over its lifetime, and these acquired changes are passed to the next generation (d) a and b (e) a, b, and carrow_forwarddescribe the modern theory of evoluton and discuss how it is supported by evidence from two of the following three areas a.population genetics b.molecular biology c.comparative anatomy and embryology evolution is one of the major unifying concepts of modern biology.explain the mechanism that lead to evolutionary change.describe how scientists use each of the following as evidence fornevolution a.bacterial resistance to antibiotics b.comparative biochemistry c.the fossil recordsarrow_forward
- Evolutionary change caused by natural selection results in species witha. greater complexity.b. less complexity.c. greater reproductive success in their native environment.d. the ability to survive longer.arrow_forwardWhich of the following most likely demonstrates that classification is the basis of evolutionary relatedness? A. Organisms that share similar characteristics are impliedly understood to have common ancestors, thus having an evolutionary relationship. B. Classification is to organize organisms into groups based on their differences and similarities and evolutionary history, so as evolution changes, classification will also change C. Classification based on evolutionary relatedness always infer that all organisms that evolved similarly shares the same history. D. Homologous structures among organisms depicts the same evolutionary history or paths.arrow_forwardMutations cause variations among individuals. If these variations provide an advantage to individuals, then the resulting traits are known as adaptations. Which of the following statements about adaptations is incorrect? A. They are structural or physiological in nature. B. They modify the behaviour of organisms. C. They provide a selective advantage in any environment. D .They increase reproductive success of organisms.arrow_forward
