The evolution of birds does NOT include Group of answer choices evidence for a close relationship with the major group of dinosaurs known as theropods. the only examples of fossilized feathers. reduction and fusion of digits in the hand over time. the transitional fossil known as Archaeopteryx, which had teeth and claws like a dinosaur, but wings and a beak like modern birds.

Archaeopteryx represents a group of transitional fossils between older (extinct) dinosaur lineages and modern (extant) ones, i.e., birds. What does the phylogenetic position of Archaeopteryx tell us about the evolution of morphological adaptations for flight in birds with respect to the relative timing of the evolution of feathers vs. muscular and skeletal modifications?

The cetaceans (whales, dolphins, and porpoises) are marine mammal descendants of land mammals. If you are studying a fossil that is a possible evolutionary link between early cetaceans and land mammals, which of the following characteristic(s) would you expect to find? Choose all of the answers that apply. a. Fins. b. Gills. c. Wings. d. Cartilaginous skeleton. e. None of the above. 2. Archaeopteryx is a bird-like dinosaur that is thought to be the evolutionary link between non-avian feathered dinosaurs and modern birds. a. Describe two characteristics that Archaeopteryx may have had and why these characteristics suggest that it may be the evolutionary link between non-avian feathered dinosaurs and modern birds. 3. b. If an extremely well-preserved example of Archaeopteryx was found, what other technique could you use to prove that Archaeopteryx is the missing link between non-avian feathered dinosaurs and modern birds?
