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

The tree below shows a proposed phylogeny of the three broadest mammal groups. monotremes marsupials eutherians Figure 1: Phylogenetic relationsbips between defrent ypes of mammals. a. Which group of mammals branched off the earliest? b. Which letter designates the common ancestor to monotremes and marsupials? c. Indicate where on the tree (short perpendicular line) each of the following characters arose. 1. long-lived placenta 4. internal gestation (rather than in egg) 2. body hair 5. long-term gestation 3. production of milk for young 6. live birth (rather than egg laying e. Which of the above characters are shared ancestral characters of eutherians? List all that apply.

Differentiate Australopithecus afarensis from Australopithecus africanus. Basis A. afarensis A. africanus a. Discoverer     b. cultural means of adaptation     c. diet     d. greatest achievement     e. size of the skull     f. brain mass     g. timeline of survival on earth     h. specific habitat     i. height and size

The biome in which anatomically modern Homo sapiens probably initially evolved was the: A. Asian steppe. B. Tropical rainforest. C. African savanna. D. Australian desert. E. North American steppe.

One hypothesis for the Cambrian explosion was an increase in predator-prey relationships. It is thought that the resulting co-evolution of predator and prey may have been a factor in the rapid speciation of animals seen during this time. What findings in the fossil record would most support this? Group of answer choices a. increased incidence of larger-bodied animals b. increased incidence of sessile animals c. decreased incidence of animals with bilateral symmetry d. increased incidence of animals with radial symmetry e. increased incidence of shells, bony plates, spines, and/or claws

Why was Jean Baptiste Lamarck wrong about the mechanism of evolution?   A. Because giraffes haven't evolved in billions of years.    B. Because individuals do not pass on any traits that they acquire during their lifetime.   C. Because individuals can change their traits during their lifetime and pass on those traits to their offpsring.    D. Because he misunderstood the structure of DNA.
