Behavior - Biology

Biology

In humans, behavior is believed to be controlled primarily by the endocrine system and the nervous system. It is most commonly believed that complexity in the behavior of an organism is correlated to the complexity of its nervous system. Generally, organisms with more complex nervous systems have a greater capacity to learn new responses and thus adjust their behavior.

Behaviors can be either innate or learned, however, current research in the Human Microbiome Project points towards a possibility that human behavior may be influenced by the composition of the microbe population within a human body.

Behavior can be regarded as any action of an organism that changes its relationship to its environment. Behavior provides outputs from the organism to the environment.
