Mehr aus der Welt der Biologie:
Da die Welt bekanntlich fraktal aufgebgaut ist, bilden nicht nur Gruppen von Menschen Schwärme, sondern auch einzelne Individuen, und darunter auch deren Organe.
As Dr. Couzinâ€™s model predicted, the human swarm made a quick, unconscious decision about which way to go. People tended to follow the largest group of leaders, even if it contained only one additional person.
Dr. Couzin and his colleagues describe the results of these experiments in a paper to be published in the journal Animal Behavior.
The rules of the swarm may also apply to the cells inside our bodies. Dr. Couzin is working with cancer biologists to discover the rules by which cancer cells work together to build tumors or migrate through tissues. Even brain cells may follow the same rules for collective behavior seen in locusts or fish.
â€œOne of the really fun things that weâ€™re doing now is understanding how the type of feedbacks in these groups is like the ones in the brain that allows humans to make decisions,â€ Dr. Couzin said. Those decisions are not just about what to order for lunch, but about basic perception â€” making sense, for example, of the flood of signals coming from the eyes. â€œHow does your brain take this information and come to a collective decision about what youâ€™re seeing?â€ Dr. Couzin said. The answer, he suspects, may lie in our inner swarm.
