question
As a corollary to the idea that primates emerged as an adaptation to an arboreal environment, Matt Cartmill proposed that
answer

question
While flipping through the channels, you stop on a television program about primate evolution. The host says that there is a 6-million-year gap in the fossil evidence between the latest Oligocene catarrhines and the earliest Miocene proconsulids, which could mean that primates disappeared from Earth and evolved anew some time later. Your roommate comes running when you start yelling at the television,
answer
"The resemblance between the Fayum catarrhines and the Miocene proconsulids in skull form and dentition suggests an evolutionary relationship, even if the direct fossil evidence isn't there!"

answer
Georges Cuvier
question
A valid criticism of the idea that anthropoids evolved independently in Africa and South America is that
answer
c. there are striking similarities between Old and New World primates not only in phenotype but also in genotype.
question
The common ancestor of all later catarrhines, Old World Monkeys, and hominins was likely
answer

question

answer
Europe; Asia
question
A valid criticism of the arboreal hypothesis of primate origins is that
answer
the opossum is also an arboreal mammal but did not develop uniquely primate traits.
question
Your classmate, whose part-time job entails reorganizing the paleoanthropology lab on campus, asks you to take a look at a skeleton that she thinks is from a primate. After noting the absence of a postorbital bar, nails, and an opposable thumb, you tell her that
answer
she should label this skeleton as a plesiadapiform rather than as a primate.
question
While walking across campus, you overhear a guy telling his girlfriend that the origin of every human ancestor was in Africa. You stop him and explain that he is not completely correct because
answer
based on the current fossil evidence, Asia could equally likely be the place where higher primates originated.
question
Your biology instructor says in class that the fossil remains of primates from the Eocene demonstrate that they were nothing like the primates of today. After class, you argue with him, noting that
answer
a variety of primate traits, such as convergent eyes, grasping digits, and a large brain, are common to both Eocene primates and those of today.

answer
leaves, nuts, and fruits.
question
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:
answer
differences in ability to exploit the habitats that resulted after a change in global climate.
question

answer
orangutan
