Towards the Big History of information. Approaching the origins of information behaviour

A palaeontological analysis of the evolutionary steps of Metazoa is tracing back the appearance and first steps of information behaviour as far as the Proterozoic Eon. Either the neural cell or the nervous system or the eyesight did not trigger the appearance of the information behaviour, but it did a novel way of diet. Carnivorous diet appeared on Earth slightly before the information behaviour as a completely new way of feeding - and what is more important: the application of light into the behavioural complexes as a radically innovative survival supporting tool. A genetic toolkit was ready for Metazoa, and the combination of the neural system, eyesight and carnivorous diet initiated the information behaviour. We provide an answer for this simple question: why did the carnivorous diet result in the first disruptive innovation in information behaviour? The junction of Big History, palaeontology and information history provides many challenging new aspects for further research.
