Exam 9: Primate Origins and Evolution: The First 50 Million Years

The skeleton of most Miocene apes was more like that of living monkeys than like that of living apes.

A press release on the findings from a dig in the Bighorn Basin of Wyoming report the finding of a series of extinct primate fossils that may be a link between lesiadapiforms and later primates due to an opposable big toe.The find is likely:

The earliest known South American primate is a 26-million-year-old monkey from Bolivia called:

Which of the following is NOT true of the Eocene euprimates?

The most likely contender for the common ancestor of all later catarrhines is:

The northern African fossil primate called Biretia may be an early anthropoid,based on the morphology of its:

If you are examining the fossil remains of the genus Dryopithecus,they are most likely from where?

Apes went extinct in southern Europe (e.g.,France,Spain,Italy,Greece)during the late Miocene,probably as a result of:

While reading a journal article on the evolution of primate characteristics you note that the author supports the arboreal hypothesis as the driver of the primate evolution.Which of the following arguments could you develop in response to this article?

During the Miocene epoch of the Cenozoic era,there was an adaptive radiation of which kind of primate?

Which of the following is NOT one of the main hypotheses to explain primate origins?

Platyrrhine fossils first appear in the South American fossil record during the late Oligocene epoch.Since they are not found in earlier fossil-bearing sediments,and South America at that time was essentially an island continent,how do scientists think they got there?

If you are digging in a 20-million-year-old fossil site in eastern Africa,which primate are you most likely to come across?

Primitive Old World monkeys from the mid- to the late Miocene of Africa are members of which family?

Which anatomical feature would you expect to find in the fossil remains of a nocturnal species?

Which of the following apes has been proposed as the last common ancestor of living African apes and humans?

Adapids had a tooth comb in the lower jaw,like living lemurs.

The space between the canine and the first premolar in the lower jaw of some primates is a(n):

Which of the following is NOT a typical primate trait?

Early fossil primates from the Eocene would most likely have shared their habitat with:
