Arboreal adaptation and
A suite of physical traits that enable an organism to live in trees.
Refers to the lower molars, in old world monkeys that have two ridges
Organism's that move by Brachiation, or arm-swinging.
Canine-premolar honing complex
The dental form in which the upper canines are sharpened against the lower third premolars when the jaws are opened and closed.
The numerical description of a species' teeth, listing the number, in one quadrant of the jaws, of incisors, canines, premolars, and molars.
Characteristics present in only one or a few species of a group.
A space between two teeth
A diets flexibility in adapting to a given environment
Refers to those organism's that normally are awake and active during daylight hours.
The cladistic classification for the primate group that consists of anthropoids and tarsiers
Humans and human ancestors in a more recent evolutionary taxonomy; based on genetics.
An enamel ridge connecting cusps on a tooths surface
Refers to those organism's that are awake and active during the night
The portion of the anterior brain that detects odors
Refers to primates' thumb, in that it can touch each of the four fingertips, enabling a grasping ability
The time and energy parents expend for their offsprings benefit.
The evolutionary relationships of a group of organisms.
A fist-like grip on which fingers and thumbs wrap around an object in opposite directions
An organism's use of an anatomical feature in a way unrelated to the feature's original function
A precise grip in which the tips of the fingers and thumbs come together, enabling fine manipulation
A tail that acts as a kind of hand for support in trees, common in new world monkeys.
Characteristics present in multiple species of a group
The naked surface around the nostrils, typically wet in mammals.
Refers to a premolar adapted for cutting.
The cladistic classification for the primate group that consists of lorises and lemurs
Anterior teeth (incisors and canines) that have been tilted forward, creating a scraper.
Hominoids' pattern of lower molar cups
What's the difference between communication, speech, and language
Language and speech help us communicate,
