17. Which of the following could be a potential reason for the shift in spatial Shh expression in embryonic feather buds? A nonconservative substitution within the coding region of Shh A nonconservative substitution within a transcription factor that now allows it to bind to silencer elements upstream of Shh within the entire scale/feather bud An inversion mutation within the chromosome containing Shh that allows for the close proximity of Shh and new enhancer elements A conservative substitution within the coding region of Shh A duplication mutation of Shh that allows different paralogs to be expressed in different domains of the embryonic feather bud
18. Tyrannosoids share a most recent common ancestor (MRCA) with: The MRCA of the clade containing Oviraptorosaurs, Dromeosaurids, Archaeopterix, and Living birds Oviraptorosaurs Compsognathids The MRCA of the clade containing Allosaurids and Compsognathids Living birds
19. Which of the following characteristics is ancestral in Oviraptorosaurs? Lack of semilunate carpal in hand Lack of hollow bones Lack of three digits in hand Lack of bird-like sleeping position Lack of tufted feathers
