Answer

71. Analogous structures are features with similar functions but different origins; example: wings of birds and insects. ### 72. More closely related. ### 73. Differences in traits among individuals. ### 74. Ability to survive and reproduce. ### 75. Transfer of genetic material between populations. ### 76. Evolution of new species. ### 77. Genetic equilibrium. ### 78. Mutual evolutionary influence between species. Explanation 1. Define analogous structure Analogous structures are features in different species that perform similar functions but do not share a common evolutionary origin. Example: Wings of birds and insects. 2. Determine relation based on protein similarity If animals share many proteins, they are more closely related to each other due to shared ancestry. 3. Define variation Variation refers to differences in traits among individuals within a population. 4. Define fitness Fitness is the ability of an organism to survive and reproduce in its environment. 5. Define gene flow Gene flow is the transfer of genetic material between populations through migration. 6. Define speciation Speciation is the process by which new distinct species evolve from existing ones. 7. Identify term for no genetic change When there is no genetic change to a population, it is known as genetic equilibrium. 8. Define coevolution Coevolution is the process where two or more species influence each other's evolution.
