Biodiversity & Evolution Virtual Lab (BIOL 1405)- Fall 2020 Domestic Platypus Gecko Alligator Triceratops Velociraptor Archaeopteryx Pigeon cat Beak replaces teeth AVES MAMMALIA Flight Feathers COELUROSAURIA Embryo attaches to mother's uterus Bowed ulna, Feathers DINOSAURIA Females lactate Hip socket with large perforation ARCHOSAURIA Specialized lower jaw opening REPTILIA Skull with two post-orbital openings AMNIOTA Embryo develops in water-tight egg on land Figure 4. A simple phylogeny showing the relationship of a modern bird, a pigeon, to other vertebrate animals. Questions to answer for next lab session. 1. Can the pigeon be a reptile (a member of clade Reptilia) as well as a dinosaur? Explain your answer using what you've learned about phylogenies. 2. Does a pigeon have a skull with two post-orbital openings and a hip socket with a large perforation? How do you know based on the phylogeny? 3. Is Triceratops more closely related to the pigeon or to the alligator? Explain your answer, 4. Is the platypus more closely related to the domestic cat or to the gecko? Explain your answer. 5. Both alligators and pigeons have well-developed parental care strategies where the young are attended to when they are juveniles. Based on the phylogeny in Figure 3, what type of parental care would you predict for Velociraptor or Triceratops? Is there evidence of parental care among fossil dinosaurs? If so, does that agree with what the phylogeny predicts?
