Whale skeletons contain nonfunctional pelvic bonesa. as a result of convergent evolution.b. due to catastrophism.c. because whales evolved from ancestors that had hind legs.d. because the bones might be needed for a future adaptation.

Which of the following early hominins exhibits the most morphological similarities with the last common ancestor of humans and chimpanzees? a. Orrorin tugenensis b. Sahelanthropus tchadensis c. Australopithecus anamensis d. Ardipithecus ramidus

The H. erectus site of Zhoukoudian is significant because A. It represents the first time hominins inhabited a cave site. B. The fossils date to approximately 100,000 years ago. C. The fossils are the oldest from Eastern Asia. D. 40-50 individuals, stone tools, and food remains were found.

Which of the following examples provides biogeographical evidence for the process of evolution?   a. Pythons retain leg bones within their body   b. Marsupials evolved in Australia when it separated from other landmasses   c. Whales are related to hippos because they have similar pelvic and leg bones   d. All organisms have DNA   e. Both B & D

Of the following, which one is an example of an evolutionary explanation (as opposed to a functional explanation)?A. People evolved a fear of snakes because many snakes are dangerous.B. Humans have a (tiny) tailbone because our ancient monkey-like ancestors had a tail.C. People evolved an ability to recognize faces because that ability is essential for cooperative social behaviors.D. People evolved a tendency to form long-term male–female bonds because human infants benefit from the help of two parents during their long period of dependence.

It is thought that jaws, which are found in the higher vertebrates, evolved from: a. progressive hardening of the cyclostome mouth. b. cartilaginous arches used to support gills. c. small bones associated with the brain capsule. d. the bony teeth found on lamprey tongues.

Along comes Dr Phil Bell and deep in the mines of Lightning Ridge, finds an amazingly preserved pterosaur that preserves feathers. He hypothesises that this means that feathers must have evolved before the origin of dinosaurs and therefore must have been primitive. How would you go about testing this hypothesis of feather origins?

Lampreys are jawless fish. Which conclusion about lamprey evolution is supported by the evidence in the diagram?     A. Lampreys developed after hinged jaws formed.   B. Lampreys once had hinged jaws but lost them during evolution.   C. Lampreys are invertebrates and could not develop hinged jaws.   D. Lampreys diverged from other vertebrates before hinged jaws evolved.
