If this model continues, with no major changes to the environment, what do you expect to happen? A) rabbits will continue to get lighter over time B) there is no way to predict because mutations are random C) mutations will all die out leaving only the original fur color D) dark gray fur will become the common phenotype because it favors survival
Are gene mutations caused by selective pressures in the environment? In other words, do gene mutations arise in an organism out of need or want? Group of answer choices A. No, because gene mutations are not purely random. B. Yes, because gene mutations are not purely random. C. No, because gene mutations are purely random. D. Yes, because gene mutations are purely random.
Mutations 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.
The fact that DNA sequences are more similar in more closely related organisms is evidence of what? a. optimal design in organisms b. adaptation c. mutation d. descent with modification
Which of the following does not support the idea of descent with modification? A. Organisms and the cells that they are composed of arise from DNA B. When organisms reproduce they generate new copies of DNA to pass down to their offspring C. We inherit traits from our ancestors because in possess molecules of their DNA that you received from your parents D. In the process of DNA replication, mutations occur with the goal of increasing an organism's fitness
Which of the following is true about adaptation? a) It occurs through the inheritance of acquired characteristics b) It always results in the evolution of new traits c) It is a result of chance mutations d) It is the result of natural selection acting on heritable variation
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.
Evolutionary Thought: answer the question in essay form. Explain the benefits, effects, and contributions of the Five Agents of Evolutionary Change
What result in adaptation comes from natural selection?
How does the study of the field of archaeology help one to study evolution? a. Look for patterns in evolution b. To study human emotions c. To study evidence of fossil records d. To understand Darwin's theory of evolution
Evolutionary biologists often say that evolution “selects for outcomes” not for the particular genetic changes that lead to that adaptive outcome. Given that perspective, is it surprising that different gene mutations might be involved in the evolution of the same trait (such as light skin or adaptation to living in high mountains)? Why or why not?
Why was Jean Baptiste Lamarck wrong about the mechanism of evolution? A. Because giraffes haven't evolved in billions of years. B. Because individuals do not pass on any traits that they acquire during their lifetime. C. Because individuals can change their traits during their lifetime and pass on those traits to their offpsring. D. Because he misunderstood the structure of DNA.
