Which of the following distinguishes Khorapithecus from Sivapithecus? Khoratpithecus's broad front teeth and a flat surface on the tongue side of the canines make it more similar than Sivapithecus to living orangutans.
How was Lucy different from modern humans?
Some experts argue that Lucy was in some ways more adapted to walking upright than a modern human, whose pelvis has to be a compromise between bipedal locomotion and the ability to give birth to large brained babies.
What is the difference between Miocene apes and modern apes?
A difference between Miocene apes and modern apes is the: size of the hands. If you are examining the fossil remains of the genus Dryopithecus, they are most likely from where?
How do the teeth of Old World monkeys and apes differ?
How do the teeth of Old World monkeys and apes differ? Apes have a Y-5 pattern of cusps, whereas Old World monkeys have a bilophodont pattern. Old World monkeys have a 2/1/3/3 dental formula, whereas apes have 2/1/2/3. Apes have a tooth comb, but Old World monkeys do not.
Which trait differentiates hominids from other primates?
This family, called hominids, includes only humans and their human- like ancestors. The main characteristic that separates hominids from other primates is bipedalism. Bipedalism means "walking primarily upright on two feet." Evidence of bipedalism can be seen in a primate's skeletal structure.
What is the difference between a Unifacial and a bifacial tool quizlet?
What is the difference between a unifacial and a bifacial tool? Unifacial tools have one sharp edge, whereas bifacial tools have two sharp edges.
What does the short calcaneus bone of Eosimias demonstrate?
What does the short calcaneus bone of Eosimias demonstrate? The ankle of this animal is anthropoid-like.
What is a difference between Miocene apes and modern apes?
A difference between Miocene apes and modern apes is the: size of the hands. If you are examining the fossil remains of the genus Dryopithecus, they are most likely from where?
How do Haplorhines differ from Strepsirhines?
Strepsirhines have longer snouts, smaller brains and a more highly developed sense of smell than haplorhines. Haplorhines have shorter faces, larger brains and a more highly developed sense of vision than Strepsirhines; their eyes face more forward than the eyes of strepsirhines.
What was so special about Lucy?
Lucy was one of the first hominin fossils to become a household name. Her skeleton is around 40% complete – at the time of her discovery, she was by far the most complete early hominin known.
How do we know Lucy was a hominid?
Johanson suggested taking an alternate route back to the Land Rover, through a nearby gully. Within moments, he spotted a right proximal ulna (forearm bone) and quickly identified it as a hominid.
What is the most distinctive feature of ape dentition which clearly distinguishes apes from Old World monkeys?
The most distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is: a Y-5 molar pattern. The evolution of apes began in Africa and continued into: Europe and Asia.
What is the major anatomical difference between monkeys and apes?
The easiest way to distinguish apes from monkeys is by the presence or absence of a tail. With only a couple of exceptions, all 260 species of monkeys have tails, but no apes have tails.
What behaviors distinguish Old World monkeys from New World monkeys?

|---|---|
| Have cheek pouches. | Lack cheek pouches. |
| Have a raised nose with narrow internasal septum. | Have a flat nose with a broad internasal septum. |

Which is a trait of apes that distinguishes them from most monkeys?
Apes are generally more intelligent than monkeys, and most species of apes exhibit some use of tools. While both monkeys and apes can use sounds and gestures to communicate, apes have demonstrated higher ability with language, and some individual apes have been trained to learn human sign languages.
What is the difference between a hominid and a hominin?
The main difference between hominid and hominin is that hominid is the family to which humans belong whereas hominin is the tribe level to which humans belong to. The tribe level occurs between the subfamily and genus.
What is the difference between hominids and hominoids?
Hominids are bipedal and stand upright. Hominoids are quadrupeds with flexible forelimbs. Note: A hominid is an intelligent human-like species that is bipedal (walks on two legs) (has a large brain and uses tools). Modern man, or Homo sapiens, is the only living species of hominid.
What is the difference between a Unifacial and a bifacial tool?
What is the difference between a unifacial and a bifacial tool? Unifacial tools have one sharp edge, whereas bifacial tools have two sharp edges.
Who were the denisovans quizlet?
A population of Pleistocene hominins known only from ancient DNA recovered from two tiny 41,000-year-old fossils deposited in Denisova Cave, Russian Siberia. Denisovans and Neanderthals are thought to share a common ancestor that left Africa 500,000 years ago.
Which of the following is a way in which Omomyoids differed from adapids?
Which of the following is a way in which omomyids differed from adapids? FEEDBACK: Eocene euprimates – The first true primates. Omomyids, unlike the adapids, had large, projecting central lower incisors, small canines, and wide variation in their premolars and molars.
What is one way haplorhines differ from strepsirhines quizlet?
Strepsirhines have a two part mandible and Haplorhines have a fused one.
