title: [Biophysical questions in ecology and environmental research. Part 1: An analysis of intelligence vs biomass development in humans (author's transl)].
abstract: A first analysis of intelligence vs. biomass development in humans shows that the increase of speed to accept new inventions appears not to keep pace with exploding population size. It is suggested to assess more accurately the "collective intelligence" of the human race, an attempt probably useful for several purposes. An equation is presented and used to calculate an upper human population limit for the world suggested by the present intelligence level. The equation suggests 1.5--2.3 billion people educated to the level of industrialized nations. The equation predicts acceptance times for innovations during the early evolution of mankind in the order of 10(6) years. Such a time span seems to be in accordance with archaeological findings for the acceptance of fire as a common tool.
