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

Which of the following was the first primate fossil ever recorded?

Based on their morphology, omomyids are probably closely related to ________ .

Discuss the reasons why Paleocene-aged plesiadapiforms should or should not be included in the order Primates.

Both Colobines and Cercopithecines appear in the late Miocene fossil record, representing the two subfamilies of living

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

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

Gigantopithecus, the largest primate that ever lived, weighed approximately

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

Based on genetic analysis of living primates calibrated by the fossil record, it is estimated that apes and Old World monkeys diverged into separate lineages around

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?
