Also called scaling; the differential proportion among various anatomical structures (e.g., the size of the brain in proportion to overall body size during the development of an individual). Scaling effects must also be considered when comparing species.
Surfaces on which an object such as a palm nut, root, or seed is placed before being struck with another object such as a stone.
Behavior that benefits another individual at some potential risk or cost to oneself.
Viewing nonhuman organisms in terms of human experience and capabilities; emphasizing the importance of humans over everything else.
Belonging to the same species, to specifically understand traits between a species. (An example would be the focus on conspecific vocalizations within nonhuman primates that we have learned about in class.)
The portion of a home range containing the highest concentration and most reliable supplies of food and water. The ____________ is frequently the area that will be most aggressively defended.
Layer. In the brain, the _____________ is the layer that covers the cerebral hemispheres, which in turn cover more primitive, or older, structures related to bodily functions and the sense of smell. The ___________ is composed of nerve cells called neurons, which communicate with each other and send and receive messages to and from all parts of the body.
The proportional size of the brain relative to some other measure, usually an estimate of overall body size, such as weight. More precisely, the term refers to increases in brain size beyond what would be expected given the body size of a particular species.
The ability to identify with the feelings and emotions of others.
Localized to one side of the brain. Being _____________ means your functional specialization of the hemispheres of the brain are used for specific activities.
The areas of the brain's cortex involved with movement. The _______________ is located at the back of the frontal lobe and is composed of cells that send information to muscle cells throughout the body.
The more recently evolved portions of the cortex of the brain that are involved with higher mental functions and composed of areas that integrate incoming information form different sensory organs.
Actions that benefit another individual even when there is no reward to the performer. _____________________ include sharing, assisting, and comforting and in humans are motivated in part by empathy and compassion.
The portion of a home range actively defended against intrusion, particularly by members of the same species.
