- A ship was caught in a storm and landed on a small island in the middle of the South Pacific. For generations, no one encountered this small colony who, despite the odds, made a thriving settlement on their island. After many years, what characteristics would be unique about this island population? a. The people would look very different from each other, and may have evolved some odd characteristics that aren't seen in other humans. b. The people would look very different from each other, and may exhibit abnormally high occurrences of genetic diseases that are rare in the general human population. c.The people would look very similar to each other, and may exhibit abnormally high occurrences of genetic diseases that are rare in the general human population. d. The people would no longer be considered humans after evolving independently for several generations.arrow_forwardPlease answer question 18arrow_forwardA student lists statements about how a species adapts to the environment. One statement needs to be edited for accuracy. 1. Variation in a species occurs from predictable mutations. 2. Variation exists in the phenotypes of the species. 3. Physical characteristics influence an organism's ability to utilize resources. 4. Physical characteristics affect an organism's ability to reproduce. Which statement should be edited, and what should the change be? O Statement1-Variation in a species occurs from random mutations. O Statement 2-Variation exists in the genes of the species. Statement 3-Physical characteristics influence an organism's ability to find resources. O Statement 4-Behavioral characteristics affect an organism's ability to reproduce.arrow_forward
- Answer the followingarrow_forwardThe three beetle species live in the same ecosystem, and they likely evolved from the ancestral species that colonized the region. Which statement best explains how descent with modification influenced speciation in these beetles? A. The ancestral species carried neutral gene mutations that spontaneously caused speciation when they colonized the region. B. The ancestral species randomly diverged into three species before colonization and then colonized the regions that best suited their new adaptations. C. After colonization, small groups separated from the rest of the ancestral species and developed different adaptations that helped them survive and reproduce. D. After colonization, the large group interbred until they developed enough neutral genetic mutations for speciation to occur.arrow_forwardA subpopulation of a species of birds migrates to a different location from the rest of the species for breeding purposes. How might the genes change in the subpopulation? A. Their genes would change randomly and eventually revert to normalcy, which would allow the subpopulation to return to the main population. B. Their genes would change to better allow them to survive and reproduce in their new location. C. Their genes would not change at all and they would merely be a subpopulation living in a different location. D. Their genes would change so that they would continue to be well-adapted to their former location.arrow_forward

Group of answer choices a. genetic drift b. convergent evolution c. mutation d. homology e. gene flowarrow_forwardTwo related populations can mate with each other but don't because a mountain range separates them. What type of reproductive isolation does this describe?A. Temporal isolationB. Behavioral isolation C. Habitat isolation D. Mechanical isolationarrow_forwardSeveral very distantly related species (e.g., bats, birds, insects) have evolved the capability of flight. The most recent common ancestor of insects and vertebrates likely lived over 500 million years ago and was flightless. This independent evolution of flight in multiple, distantly related taxa is an example of what evolutionary process/pattern? a. Evolutionary reversal b. Convergent evolution c. Speciation d.
