The idea posits that, in general, the most fit organisms instinctively behave according to some natural rule (often, these rules vary among and are specific to the species).

Matching and reinforcing human and animal responses to a random number generator he was able to have humans and other organisms behave "randomly".

According to classical evolutionary theory, an organism will only behave in ways that maximize its own fitness.

Biology looks at how animals and other organisms behave and work, and what they are like.

They demonstrated that reinforcers could be delivered on schedules, and further that organisms behaved differently under different schedules.

On a behavior level, buildings mimic how an organism behaves or relates to its larger context.

The organisms used should be disease-free and appear healthy, behave normally, feed well, and have low mortality in cultures, during holding, and in test control.

Later, he turned to the flow of information outside the organism, and how physics constrains how organisms behave.
