The serengeti region of africa contains a population of cheetahs and a population of lions. studies have shown that the cheetah population has very low genetic diversity, while the genetic diversity of the lion population is quite high. the cheetah population is also much smaller than the lion population. both populations are vulnerable to infection with a particular virus that can be fatal in both species. what is the most likely outcome if both populations are infected with this virus? a. the cheetah population is more likely to survive because lower genetic diversity increases immunity to viruses. b. the lion population is more likely to survive because larger populations are immune to viruses. c. the lion population is more likely to survive because it is more likely to have individuals with traits to combat the virus. d. the cheetah population is more likely to survive because there are fewer individuals for the virus to attack.

Archeologists have discovered three sites showing conclusive evidence for the mastery of fire in tanzania, from a period slightly after the time that homo habilis was present in africa. these sites clearly were founded by homo erectus, the descendent species of homo habilis that migrated north, out of africa and into asia. homo erectus was known to have mastered fire, from ample evidence at sites in asia. there is no reason to attribute mastery of fire to homo ergaster, the descendent species of homo habilis that remained in africa. which of the following is an assumption on which the argument depends? (a) before their migration, homo erectus occupied african territory as far south as tanzania.(b) the strain of migration provided the selective pressure motivating homo erectus‘ mastery of fire.(c) homo ergaster would not have derived as much benefit from the mastery of fire as did homo erectus.(d) homo ergaster inherited all cultural knowledge from homo habilis, a species that did not have mastery of fire.(e) homo ergaster did not occupy regions as far south as tanzania until well after the time of these three sites.
