Nikolaas "Niko" Tinbergen (April 15, 1907 – December 21, 1988) was a Dutch ethologist and ornithologist who shared the 1973 Nobel Prize in Physiology or Medicine with Karl von Frisch and Konrad Lorenz for their discoveries concerning organization and elicitation of individual and social behaviour patterns in animals.

Origins

Born in The Hague, Netherlands, he is also noted as the brother of Jan Tinbergen, who won the first Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel. He had a third eminent brother, Luuk Tinbergen.

Tinbergen's interest in nature manifested itself when he was young. He studied biology at Leiden University and was a prisoner of war during World War II. Tinbergen's experience as a prisoner of the Nazis led to some friction with longtime intellectual collaborator Konrad Lorenz, and it was several years before the two reconciled. After the war, Tinbergen moved to England, where he taught at the University of Oxford.

He married Elisabeth Rutten and they had five children. Tinbergen died December 21, 1988, after suffering a stroke at his home in Oxford, England.

Main article: Tinbergen's four questions

He is well known for originating the four questions he believed should be asked of any animal behaviour, which were:

Proximate mechanisms:

• 1. Causation: what are the stimuli that elicit the response, and how has it been modified by recent learning? How do behaviour and psyche "function" on the molecular, physiological, neuro-ethological, cognitive and social level, and what do the relations between the levels look like? (compare: Nicolai Hartmann: "The laws about the levels of complexity")
• 2. Development (Ontogeny): how does the behaviour change with age, and what early experiences are necessary for the behaviour to be shown? Which developmental steps (the ontogenesis follows an "inner plan") and which environmental factors play when / which role? (compare: Recapitulation theory)

Ultimate mechanisms:

• 3. Function (Adaptation): how does the behaviour impact on the animal's chances of survival and reproduction?
• 4. Evolution (Phylogeny): how does the behaviour compare with similar behaviour in related species, and how might it have arisen through the process of phylogeny? Why did structural associations (behaviour can be seen as a "time space structure") evolve in this manner and not otherwise?

In ethology and sociobiology causation and ontogeny are summarized as the "proximate mechanisms" and adaptation and phylogeny as the "ultimate mechanisms". They are still considered as the cornerstone of modern ethology, sociobiology and transdisciplinarity in Human Sciences.
