Explain why molecular techniques are needed to support the neutral theory of evolution

Researchers studied the effects of artificial selection on largemouth bass. The fish are bred in fisheries to have the desired trait of a high vulnerability rate (HVR) so they are easily caught by human anglers, and then released in artificial ponds and lakes that allow recreational fishing. Within three generations, a fishery can produce a population saturated with members that have the HVR trait in the study. Researchers compared the health of three groups of fish, as measured by the time it took them to recover after exercise: fish with HVR, fish with a low vulnerability rate (LVR), and a control group of wild fish. Each groups' cardiac output, heart rate, and stroke volume are represented in the graph. 85 80 75 70 65 60 55 50 Control LV HV Group of Fish Does the practice of artificial selection in fisheries of largemouth bass for a greater frequency of members with HVR affect the variability in their heart rate, and why? No, artificial selection produces fish with the HVR trait…

Match the terms to their descriptors. NOTE: If you want to change your selection, you'll need to delete the one you already chose. After you delete it, the list of choices will pop back up and you can make a different choice. Two species evolve in different directions from a common starting point Divergent evolution Two species independently evolve similar structures Homologous structures Traits that look similar but were not inherited from a common Convergent evolution ancestor Analogous structures Traits that are similar because they were inherited from a common ancestor

With two specific examples, explain why phylogenetics is a useful scientific tool for studying Organismal biology?
