Oligocene

What was Pangaea?

Pangaea was the supercontinent that existed around 200 million years ago. All current continents are derived from this land mass.

what kind of culture do primates have

Primates have material culture.

the earth is how many billion years old ?

4.6 billion years

how many teeth do humans have in each quadrant ?

8 teeth

how do Diana monkeys treat vocalizations ?

Diana monkeys treat vocalizations associated with one type of predator the same way that they treat sounds from that predator.

Which primates are excellent leapers because they have elongated tarsals?

Tarsiers

why do humans have non projecting and small canine teeth ?

The small, non-projecting canine teeth of humans are an evolutionary trend in hominins due to a shift to a soft diet and the development of tools

What is one of the key indicators of primates' adaptability?

They live in a wide range of habitats.

Who discovered an extinct ground sloth in Virginia?

Taphonomy is:

the study of what happens to an organism's remains after death

what is one of the main reasons why scientist study primate behavior ?

to address the question of why primates are social.

what doesn't The cladistic classification scheme use?

angiosperm radiation hypothesis

a derived characteristic is one that ?

appears after a group splits from a common ancestor

have scientist ever found fossil evidence of primates in Australia ?

no

Humans have ________ canine teeth.

non-projecting and small

catarrhines include ?

old world monkeys, apes, and humans

these fossil primates were nocturnal, had short snouts, and are likely ancestors of tarsiers

omomyids

the following primates are Strepsirhini

- Aye-ayes - Slow lorises - Ring-tailed lemurs

Primate fossils have been found in which continents ?

- North America - Asia - Africa

what conditions are likely to help preserve animal remains, making it more likely for them to become fossils,

- rapid burial - low levels of oxygen in the sediment in which remains are buried - no scavengers in the vicinity

Jane Goodall was the first to document all the following behaviors in chimpanzees

- tool use - meat eating - enduring mother-offspring bonds

Which trait below separates apes from monkeys?

Apes do not have a tail but monkeys do.

hypotheses about how anthropoids first reached South America,

Areas of the ocean might have been shallow and dotted with series of islands. Primates might have crossed via ocean currents, on natural rafts consisting of accumulated vegetation. However, there is currently no concrete evidence that this occurred. It seems unlikely that primates migrated from Africa to South America via the Atlantic, especially in view of the wide and prohibitive expanse of open sea separating the west coast of Africa from the east coast of South America.

______ dating is a form of absolute dating in which the sample is bombarded with fast neutrons in a nuclear reactor to measure the ratio of argon-40 to argon-39 in a sample. This method only works on igneous rock.

Argon-argon

Australia and Antarctica ((Nonhuman primates have lived on every continent except Australia and Antarctica.))

platyrrhines ancestors most likely originated in ?

africa

Which of the following residence patterns is the rarest among primates?

groups with a single reproductively active female and several males ((Groups with a single reproductively active female and several adult males are relatively rare in primate societies. It has been observed in some New World monkeys, but they do not always practice this system.))

similarities between species that are most easily explained by a shared common ancestor are

homologies

Which primate has the longest period of growth and development?

humans

The earliest New World monkey fossils come from a late Oligocene site where?

in Bolivia.

The most strongly altruistic behaviors tend to occur when ?

in primates that live with their relatives. ((presence of such behavior is part of the kin selection hypothesis, which holds that altruistic acts increase the inclusive fitness of the related group. This animation further summarizes kin selection.))

What do primatologists need to have to understand what the primate communication data they collect means?

knowledge of both context and vocalizations

relative dating methods tell us ?

whether a fossil is older or younger than another
