What are adapids and omomyids?
The adapids were lemur-like primates, while the omomyids closely resembled living tarsiers, but both had forward-oriented eyes and adaptations to life in the trees. Both these groups are relevant to yesterday's big announcement.
What are two differences between plesiadapiforms and primates?
And while primates have a versatile dentition, plesiadapiforms had very specialized anterior (front) teeth, which were separated from the posterior (rear) teeth by a large gap. In addition, Plesiadapis and other plesiadapiforms had much smaller brains than did true primate ancestors.
What is one way haplorhines differ from strepsirhines quizlet?
Strepsirhines have a two part mandible and Haplorhines have a fused one.
What is the difference between platyrrhines and catarrhines?
Catarrhines and platyrrhines are distinguished by the shape of their nostrils. Catarrhines have narrow downward facing nostrils, while platyrrhines have broad, flat, sideways facing nostrils. There are certain physical features that help set primates apart from other animals.
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.
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 difference between primates and monkeys?
A primate is an animal belonging to the biological order 'Primates', a group that contains all species of lemurs, monkeys, and apes worldwide. The term 'monkey' is generally accepted to refer to two groups of primates – New World monkeys and Old World monkeys.
What is the difference between monkey and chimpanzee?
Monkey vs Chimpanzee: Appearance Monkeys have tails while chimpanzees don't. A simple way to tell the difference between monkeys and apes is to look for a tail; monkeys have one, and apes don't, so chimps don't have one either. However, Old World Monkeys have shorter tails than New World Monkeys.
What is a valid criticism of the idea that anthropoids evolved independently in Africa and South America?
What is a valid criticism of the idea that anthropoids evolved independently in Africa and South America? There are striking similarities between Old World and New World primates, not only in phenotype but also in genotype.
How do the arboreal hypothesis and the visual predation hypothesis differ from each other?
The arboreal hypothesis proposes that defining primate characteristics were adaptations to life in the trees, such as: grasping hands and feet, developed vision, and greater intelligence. The visual predation hypothesis proposes that: primate traits arose as adaptations to preying on insects and small animals.
Are omomyids nocturnal?
Large orbits in genera such as Tetonius, Shoshonius, Necrolemur, and Microchoerus indicate that these taxa were probably nocturnal. At least one omomyid genus from the late Eocene of Texas (Rooneyia) had small orbits and was probably diurnal.
Which of the following derived characteristics did the earliest Oligopithecid primates share with modern Haplorrhines?
Which of the following derived characteristics did the earliest oligopithecid primates share with modern haplorrhines? Their eye sockets were fully enclosed by bone.
In what way does the skull of a haplorhines differ from that of an strepsirrhine?
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.
Why are plesiadapiforms not primates?
Although plesiadapiforms are similar to modern primates in a number of characteristics of their skeleton, they were still on a much lower evolutionary level, comparable perhaps to the living tree-shrews (1). Modern primates are unique among mammals in their adaptation to life in the trees.
How are Strepsirhines and haplorhines different?
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 is the difference between platyrrhines and Catarrhines?
Catarrhines and platyrrhines are distinguished by the shape of their nostrils. Catarrhines have narrow downward facing nostrils, while platyrrhines have broad, flat, sideways facing nostrils. There are certain physical features that help set primates apart from other animals.
What are the key differences between Parvoorders catarrhines and platyrrhines?
Platyrrhines refer to the parvorder Platyrrhini, consisting of flat-nosed simians, having more flatter noses than those other simians, with sideways-facing nostrils, while catarrhines refer to the second parvorder, parvorder Catarrhini, consisting of simians with hooked noses with nostrils facing downward.
In what way does the skull of a Haplorhines differ from that of an Strepsirrhine?

Some characteristics that have distinguished hominins from other primates, living and extinct, are their erect posture, bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use and, in some cases, communication through language.
What are the key differences between Parvoorders catarrhines and Platyrrhines?
