Intelligence (biology)

From Citizendium, the Citizens' Compendium

In biology, intelligence refers to the ability of an organism to adapt to its environment through learning and memory. Interindividual differences in intelligence reflect differences in the 'quality' of learning and memory, where quality may consist in efficiency, speed, capacity, and/or structure, among other factors, all of which remain under active investigation. To measure the intelligence of an individual requires performing some kind of intelligence testing, in which case what the intelligence test measures defines 'intelligence' in that circumstance.
