1. The advantage of bipedalism is

• having the ability to move through the treetops and clinging to vines.
• having the ability to run faster.
• freeing of hands to carry objects and use tools.
• increased brain size.
• All of the answer choices are correct.

2. Select the statement that correctly describes the evolution and spread of Homo sapiens.

• Homo sapiens evolved in Africa and subsequently migrated to all the continents, with the farthest continents east from Africa being colonized last.
• Homo sapiens evolved from Homo erectus in Asia and then spread both west and south to Europe and Africa, replacing Homo ergaster and Homo heidelbergensis, and east toward North America.
• Three species of Homo gave rise to Homo sapiens in different parts of the world at approximately the same time: Homo ergaster in Africa, Homo erectus in Asia, and Homo neanderthalensis in Europe.
• Homo sapiens evolved in Asia and Africa at the same time, and the African group spread northward toward Europe, and the Asian group spread east toward Australia and North America.

3. Hominoids include

• New World monkeys, Old World monkeys, and apes.
• gibbons and all of the great apes.
• prosimians, monkeys, and gibbons.
• New World monkeys and Old World monkeys.
• prosimians, New World monkeys, and Old World monkeys.

4. One of your friends asks you, "If humans are related to chimpanzees, then you must think that humans evolved from chimps. Why, then, are there still chimps?" What is the best response to this?

• It is true that, in certain regions of the world, humans evolved from chimps; in other regions the selective pressures did not favor evolution of chimps into humans, so chimps still exist.
• Humans did not evolve from chimps. In fact, chimps evolved from humans. The cladograms are just usually drawn to show
• humans at the top.
• Humans did not evolve from chimps. Humans and chimps share a common ancestor that was neither a chimp nor a human.
• Well, that's a good point. I had never thought about that.
• While it is true that humans evolved from chimps, this does not mean that all chimps will become humans.

5. In enveloped viruses, the viral spikes are

• proteins on the surface of the envelope.
• individual capsid proteins.
• tail fibers that aid in attachment to the host cell.
• receptors on the host cell membrane to which the virus binds.

6. The three groups in the primate lineage are

• chimpanzees, gorillas, and humans.
• prosimians, monkeys, and hominoids.
• monkeys, gibbons, and orangutans.
• hominines, hominids, and hominoids.
• gorillas, bonobos, and chimpanzees.
