who have the largest brain for body size
HUMANS
26
What is strepsirhini
Strepsirrhini ("moist-nosed" emphasis on sense of smell
27
what is haplorhini
Haplorhini is a suborder of primates containing the tarsiers and the simians
28
what primates belong to the infraorder lemuriformes?
Lemurs
29
what primates belong to the infraorder trasiiformes?
tarsiers
30
characteristics of lemurs & lorises | eyes
Nocturnal; eyes adapted for night vision; no color vision. Have Large eyes Have Stereoscopic Vision
31
characteristics of lemurs & lorises | smell
well dveloped smell; protruding snout; nostrils surrounded by a rhinarium ; upper lips attached to to gums by a philtrum (STREPSIRHINE; NOSE WITH CURVED NOSTRILS
32
characteristics of lemurs & lorises | hands & feet
prehensile hands & feet , but limited opposability of thumbs second toes that end in claws- grooming claws THEY GOT DENTAL COMBS TOO
33
explain dental comb
a dental structure found in some mammals, comprising a group of front teeth arranged in a manner that facilitates grooming, similar to a hair comb. The toothcomb occurs in lemuriform primates
34
what do lemurs eat
variety of foods, omnivorous in some cases
35
do lemur species vary in size
ya from 15 pounds to few ounces
36
tarsiers characteristics | where?
certain islands in east asia
37
tarsier characteristic | eyes
STRICTLY nocturnal with very large eyes
38
what do tarsiers lack
rhinarium
39
type of face tarsiers have
flat face
40
do tarsiers have more or less emphasis on smell compared to lemurs
TARSIERS LESS
41
what do tarsiers use to groom
grooming clawes, they dont have dental comb
42
describe size of tarisers
very small
43
foods that tarsiers eat?
insects, lizards
44
What are the chracteristics of NW Monkeys
``` platyrrhine nose (broad nose) smaller than OW stricty ARBOREAL prehensile tail (in some species) 3 premolars in each quarter of the month dental formulas 2.1.3.3. or 2.1.3.2. ```
45
what are characteristics of OW monkeys
cattarhine nose (hook nose) opposable thumbs LARGER sexual dimorphism no prehensile tail 2 premolars per quadrant DENTAL FORMULA:2.1.2.3. Both semi terrestrial + arboreal sexual skin in females SEXUAL DIMORPHISM
46
wht is sexual dimorphism
difference in body size and behavior between male and females
47
what is the estrus
he period of time when female animals are sexually excited and receptive to mating. Estrus occurs around the time of ovulation in many species.
48
what is sexual skin
a nearly hairless large swollen patch of skin around the genital area of females that becomes very prominent when they are in estrus click this icon to hear the preceding term pronounced. These areas swell with fluids and turn bright pink or red due to hormonal changes that occur in preparation for ovulation. The sexual skin also produces odors that excite males of the species. They become highly attentive to the females at this time. Sexual skins are found among many of the Old World monkey species in the subfamily Cercopithecinae (e.g., baboons) as well as the chimpanzees and bonobos.
49
what is sexual sleection
Sexual Selection is a "special case" of-natural selection, and acts on an organisms ability to successfully attract, keep and copulate with a mate
50
explain opposable thumb
your thumb moves in different directions than your fingers. That is why thumbs are also known as opposable thumbs.
51
prehensility
Prehensility is the quality of an appendage or organ that has adapted for grasping or holding.
52
what is a precision grip
A precision grip is the way you grab an object between the opposed tactile pads of the tips of the thumb and the fingers. Tactile pads are areas of the skin that are especially sensitive to pressure.
53
what are tactile pads
A tactile pad is an area of skin that is particularly sensitive to pressure, temperature, or pain. Tactile pads are characterized by high concentrations of free nerve endings. In primates, the last phalanges in the fingers and toes have tactile pads, allowing very accurate manipulation of objects.
54
what is a power grip
a power grip is the strongest human grip,
55
what is rhinarium
The rhinarium is the naked skin surface surrounding the external openings of the nostrils in most mammals
56
what is the philtrum
The philtrum, or medial cleft, is a vertical indentation in the middle area of the upper lip, common to many mammals, extending in humans from the nasal septum to the tubercle of the upper lip.
57
what is suspensory behavior
Suspensory behaviour is a form of arboreal locomotion or a feeding behavior that involves hanging or suspension of the body below or among tree branches. This behavior enables faster travel while reducing path lengths to cover more ground when travelling, searching for food and avoiding predators.
58
charactersitics of hominoids in general
bipedalism and big brains less separation between the brain and the face. walk upright smaller at the top and larger at the bottom spine of hominids also curves femur, which is the thigh bone in hominids, is angled towards the knee, which stabilizes the body in relation to gravity.
59
what hominoids belong to the family hylobatidae
siamangs and gibbons
60
what are the characteristics of hylobatidaes
smaller of all apes brachiating mode of locomotion male & female form monogamous groups siamangs produce very loud calls
61
what hominoids belong to hominidae
ponginae (orangutangs) gorillinae (gorillas) homininae (chimps, bonobos, humans)
62
what are the characteristics of the ponginae | orangutangs
``` Fairly large; pronounced sexual dimorphism long & coarse hair; orange, brown arboreal , solitary long birth intervals found in sumatra and borneo ( indonesia) ```
63
genus and species are reffered to as...
major taxa
64
family, order, class,phyla, kindgom are reffered to as
higher taxa
65
what species do humans belong to
HOMOSAPIENS
