One example is the forelimb of humans, dogs, birds, and whales. What term best describes the relationship between these structures? * Embryological Analogous Homologous no answer Vestigial Which of the following is NOT true about creationism? * no answer There is no extinction of organisms because organisms can always survive as long as they try hard enough. The earth was created only 6000 years ago because the evidence of the rocks support that idea. Any great change is due to small but cumulative changes that occur over long periods of time. All organisms are perfect because they are created to be able to survive in their habitat.arrow_forward
- Which of the following BEST describes Lamarck's idea about evolution? Species evolve into different forms in response to changes in the environment. Organisms can be classified according to their similarities. Earth is much older than previously thought. no answer More complex forms of life evolved from less complex forms. Many organisms have similar amino acid code that suggests descent from a common ancestry with modifications. This is an example of which evolutionary evidence? * Fossil record Anatomical homology Convergent evolution Biogeography no answerarrow_forwardBirds and butterflies have wings they use for flying. The wings of butterflies are made of semitransparent, tough scales. Bird wings are covered with feathers. The wings of birds and butterflies did not evolve from a common ancestor that had wings. Instead, they have evolved as a result of similar environmental pressures. Which statement best explains the evolutionary relationship of birds and butterflies? Bird and butterfly wings are a result of divergent evolution because birds and butterflies did not evolve from a winged common ancestor. Bird and butterfly wings are a result of convergent evolution because birds and butterflies evolved from a winged common ancestor. Bird and butterfly wings are analogous structures because they have similar functions, are structurally different, and are a result of convergent evolution. Bird and butterfly wings are homologous structures because they have similar functions, are structurally the same, and are a result of divergent evolution.arrow_forwardThe fossil record of evolution correlates with evidence from ______. a. the geologic record b. radiometric dating c. comparing development patterns and morphology d. comparative biochemistry e. all of the abovearrow_forward
