of this =rab or ditions ionary escen- se or 5. Describe two examples of vestigial structures that you can find among the Caminalcules. These are structures that have been reduced to the point that they are virtually useless. Ear muscles and the tail bones are examples of vestigial structures in our own species. Explain how vestigial structures provide clues about a species' evolutionary past. Illustrate your argument with vestigial structures found in humans or other real species.

1) Of all of the robust australopithecines, I am the most primitive, dated to 2.5 mya. I have an enormous sagittal crest on the top of my head, a back of the skull that looks like A. afarensis, and am quite prognathic. My discovery seemed to justify my removal from the genus Australopithecus, and the creation of an new genus with two other species sharing similar anatomy..................... 2. Why did the scientists in England not believe that Raymond Dart's Taung Child fossil was an early human ancestor?  Check all that apply. a) The Piltdown Man fossil was considered a better early human ancestor. b) It had a small brain. c) No other fossils had been found in Africa. d) It was found in caves. e)The Taung Child lacked any human-like traits.

This organism is an animal. What can you infer about its bodystructure and lifestyle (that might not be obvious from itsappearance)? This animal has a protostome developmentalpattern and a trochophore larva. Identify the major clades thatthis animal belongs to. Explain your selection, and describe whenthese clades originated and how they are related to one another.

1) describe the four distinguishing characteristics of chordata a d the structural, functional, and reproductive adaptations throughtout the group 2) discuss the evolutionary history of hominins and homo sapiens, relating our species to other ales other primates and other mammals
