EVOLUTION LINK. In what ways does evolution depend on transfer of information? In what ways does transfer of information depend on evolution?
One way to prevent a small population of a plant or animal species from going extinct is to deliberately introduce some individuals from a large population of the same species into the smaller population. In terms of the evolutionary mechanisms discussed in this chapter, what are the potential benefits and drawbacks of transferring individuals from one population to another? Do you think biologists and concerned citizens should take such actions?
Some scientists say that modern medicine and better sanitation are slowing down or altering the course of human evolution in highly developed countries today. As a result, evolution in humans today has gone from survival of the fittest to survival of almost everyone. Do you think that this idea is valid? Why or why not?

- The concept of evolution has always been connected with some notion of progress–natural selection pushing populations toward better and better adaptations to create "perfect organisms." How would you argue that evolution does not craft perfect organisms?arrow_forwardThe theory of evolution was controversial when it was first proposed in 1859, yet within 20 years virtually every working biologist had accepted evolution as the explanation for the diversity of life. Explain in at least 50 words why.arrow_forwardWhat causes variation among a population of living things and How can variation in one generation influence the next generation? Is the variation in a population will be examined as the “raw material” upon which natural selection acts. Why are there so many different kinds of living things? Comparing species that exist today reveals a lot about their relationships to one another and provides evidence of common origins. This session explores the theory of evolution: change in species over time.arrow_forward
- Which evolutionary mechanisms (natural selection, mutation, genetic drift, or gene flow) would you need to understand to predict the success of genetically modified mosquitoes to: 1. Drive the mosquito population to extinction? 2. Replace the mosquito population with genetically modified mosquitoes that can not transmit malaria?arrow_forwardSelect all the forces of evolution below. gene flow natural selection random mating genetic drift competition mutation non-random matingarrow_forwardWhich of the following is correct concerning adaptations? (Choose one.) Group of answer choices a)They always increase an organism's ability to survive better than other individuals in the population. b)They can increase an organism's ability to survive better or reproduce better than other individuals, but not both at the same time. c)They increase an organism's ability to reproduce better than other individuals in the population, in a given environment. d)They result from any mechanism of evolution.arrow_forward
- How might an evolutionary biologist explain why a species of salamander becomes blind after colonizing a cave? Group of answer choices Members of the ancestral population that colonized the cave differed in their ability to see. If maintaining the ability to see in the cave was a waste of energy, blind salamanders might actually have more offspring than those who could see. It is possible that in the cave there is a source of pollution that increases the mutation rate for a gene that makes salamanders blind. Over time, due to exposure to this chemical, the membersof the population lose their sight. There is no way to explain this in terms of natural selection. The members of this salamander species no longer needed to use their eyes. Over time, due to lack of use, they lost the ability to see.arrow_forwardOnce a mutualistic relationship evolves between two species, will natural selection and co-evolution cause the two species to become continuously more dependent on each other? Or is it possible for one to end the mutualism? Describe.arrow_forwardHow does the increasing frequency of anabiotic resistant strains of bacteria represent an example of the occurrence of evolution?

- What is environmental evolution? How do all living things share a common ancestor? What is random evolution?arrow_forwardWhich of the following statements is not true about the concept of natural selection? Group of answer choices A-Geographical isolation contributes to the formation of new species as individuals begin to adapt to different environments B-Natural selection explains the increase in the yield of kernels per corn plant over the last several thousand years C-Infers that later generations may be distinct from ancestral ones, or a new species can appear D-Selective pressures cause distinct species to develop E-Suggests that over long periods of geological time, successful variations accumulate in a populationarrow_forwardWhy are vestigial structures among organisms evidence for evolution? Give an example of another vestigial structure.arrow_forward
