22 Cards in this Set
- Front
- Back
prehensile |
-capable of grasping -ex. primate and human hands -also tails in some primates (South American) |
|
opposable digit |
-able to move to touch the other fingers -a part of prehensile hands -evident in humans and primates -derived trait |
|
Omnivorous |
-a diet consisting of many food types including plant materials, meat and insects -no dietary specialization |
|
Diurnal |
-active during the day -color vision -mammals who do this rely more on vision that olafactory |
|
Olfaction |
-the sense of smell -used heavily by nocturnal mammals |
|
Nocturnal |
-active during the night |
|
Stereoscopic vision |
-ability to perceive objects in 3-D -Eyes are placed toward the front of the face -eyes are superimposed -partly a function of the brain (visual information transmitted to both sides of the brain) |
|
Binocular vision |
-eyes placed at front of the head -allows for overlapping visual fields |
|
Neocortex |
-recently evolved portions of the cortex (outer layer) -higher mental functions -integrate incoming information from sensory organs -derived trait |
|
Arboreal |
-tree living, adapted to life in trees -evolved to be able to find leaves, bugs, etc. in trees -an adaptive niche |
|
Dental formula |
-teeth types in a mammal -numerical device that indicates the number of each type of tooth in each side of the upper and lower jaws -incisors, canines, premolars and molars Humans: 2.1.2.3 New world monkey: 2.1.3.3 |
|
Quadrapedal |
-using all four limbs to support the body during locomotion, the basic primate form of locomotion -primates use more than one type of locomotion -Arboreal vs terrestrial |
|
Brachiation |
-arm-swinging -being supported from one arm limb to the other -new world monkeys also use their tails -arms are longer than the legs |
|
Rhinarium |
-moist, hairless pad at the end of the nose seen in most mammalian species -enhances animal's ability to smell |
|
Dental comb |
-dental structure found in some mammals that allows for grooming |
|
Anthropoids |
-humans, apes, new and old world monkeys -primate order anthropoidea -based on physical similarities |
|
Prosimians |
-primate order prosimii -lemurs, tarsiers -used to explain why tarsiers are so weird -based on physical similarities |
|
Catarrhines |
-old world primates -also includes apes and man |
|
Platyhrrines |
-new world monkeys |
|
Hominoids |
-classification of apes and man |
|
Strepsirhines |
-primate suborder that includes lemurs and lorises -Revised taxonomy based upon unique derived features |
|
Haplorhines |
-the primate suborder that includes tarsiers, monkeys, apes and humans -Revised taxonomy based upon unique derived features |
