A new winged species is discovered in the Amazon rainforest. Select the evidence that supports that this species' wings are homologous to vertebrate animals and analogous to insecet wings. Check ali that apply A The wings have an underlying bone structure. B The wings are poisonous. _C_ Blood vessels are networked through the wings. -D-The wings are covered in chitinous scales. 75. Which observations illustrate shared ancestry by anatomical comparison studies? Check all that apply. The same structure has evolved to carry out different functions. B A Different structures evolve in similar ways when subjected to the same selective pressures. C A structure becomes vestigial. _D-Structures are found to be homologous. 76. Choose the true statements about species that show convergent evolution. Check all that apply. do not share a recent common ancestor must be found in the same biogeographical region A B C subject to similar selection pressures D have similar phenotypes 77. Chose the scientifie evidence that supports evolutionary theory, Check all that apply the fossil record homologous structures the molecular record intelligent design vestigial structures A B C D E 78. Why can't "scientific creationism" be considered a science? Check all that apply. It is not supported by any empirical observations. It does not obtain its principles from observation, as does science. Its assumptions lead to no hypotheses that could be tested and possibly disproved The idea of creation by a supernatural agency lies outside the realm of science A B D E-Only non-scientists believe it. 79. Select all of the following that are valid counterarguments to the idea that evolution is "just a theory." A Scientists use the word theory to describe unifying ideas B Evolution is just a collection of facts without a central theme and this is not a theory C Scientific theories are supported by many types of evidence and no empirical data refutes them. D Evolution occurred in the past, but it is not occurring in the present, so it cannot be a theory.Explanation / Answer
