Linnaeus’s taxonomic system is referred to as a “hierarchy” because:
a. each species has a “higher level” genus and “lower level” species, and are placed
within additional higher level categories.
b. species are placed in a ranked list called the “Great Chain of Being.”
c. humans are considered the most evolved species.
d. naming species officially requires approval of an appointed board of high-level
experts.
The shift from the Miocene, which had greater diversity of ape species and fewer
monkey species, to a living assemblage with greater diversity of monkey species and
fewer ape species may be the result of:
a. global climate changes that resulted in cooler, wetter environments less optimal for
ape species.
b. differences in ability to exploit the habitats that resulted after a change in global
climate.
c. cooler climates, where it is more difficult to preserve larger ape fossils.
d. declines in ape diversity, caused by competition from hominin species.
The fossils called Homo floresiensis were dated to:
