Marsupials Survived in Australia (As Opposed to Asia) Because ________.
Marsupials survived in Australia (as opposed to Asia) because ________.
A) marsupials were better adapted to the climatic conditions of Australia than were eutherians
B) marsupials were, and are, better competitors than eutherians
C) Australia had separated from Pangea, and eutherians were not able to invade Australia
D) continental drift, caused by plate tectonic processes, allowed eutherians to invade Asia and the Americas
On the back of your skull you can feel a small bump, below which is an opening where the spinal cord enters the skull. The location of this opening toward the bottom of the skull is significant in evolutionary biology for what reason?
A) It allowed for the hominin brain to grow much larger than other primates.
B) It provided greater protection for the spinal cord.
C) It occurred as a result of the change to a bipedal stance.
D) This change was necessary for the increase in size from prosimian forms to anthropoid forms.
Use the following information to answer the question.
Brown et al. and Morwood et al. reported in 2004 that they had found skeletal remains of a previously unknown type of hominin, now dubbed Homo floresiensis, on the Indonesian island of Flores. These hominins were small (approximately 1 metre tall) with small braincases (approximately 380 cubic centimetres) as compared with other hominins. The remains of H. floresiensis were found alongside handmade stone tools and the remains of dwarf elephants that also inhabited the island, suggesting that H. floresiensis was able both to make tools and to coordinate the hunting of animals much larger than itself. H. floresiensis is estimated to have lived at the site where the remains were found from at least 38,000 years ago to 18,000 years ago.
Which would be the most feasible method of figuring out to which other hominin species H. floresiensis was most closely related?
A) Compare the type of prey hunted by H. floresiensis to that hunted by each of the other hominin species.
B) Compare the average body size of H. floresiensis to that of each of the other hominin species.
C) Compare the skeletal morphology of H. floresiensis to that of each of the other hominin species.
D) Compare the estimated life span of H. floresiensis to that of each of the other hominin species.
In what respect do hominins differ from all other anthropoids?
A) lack of a tail
B) eyes on the front of the face
C) bipedal posture
D) opposable thumbs
