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 |
|

-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 |
