In the present article, a depiction of complexity versus time will be used for the construction of a novel form of a tree of life, called The Pattern of Life, comprising the biological, cultural, and scientific forms of the evolutionary process. This diagram accentuates the implication of the successive modifications of developmental programs, in the cultural and scientific realms coupled to a feedback mechanism that is decisive for the accelerating pace of complexity growth, also suggested to be of support of (...) a cautious prediction of future evolution.

In this article I analyze a regular pattern in the developmental and evolutionary processes, formed by a gradual shortening of developmental stages. This shortening is the expected result of a selection process, in the biological as well as in the cultural evolutionary process. Biology and culture are in this way unified by a common mechanism. A mathematical analysis further indicates a vital condition for a continued progress of human culture, especially for a continued progressive scientific evolution, implying continued shortening of (...) mental developmental stages by means of enhanced education.

In this paper, I discuss the concept of complexity. I show that the principle of natural selection as acting on complexity gives a solution to the problem of reconciling the seemingly contradictory notion of generally increasing complexity and the observation that most species don’t follow such a trend. I suggest the process of evolution to be illustrated by means of a schematic diagram of complexity versus time, interpreted as a form of the Tree of Life. The suggested model implies that (...) complexity is cumulatively increasing, giving evolution a direction, an arrow of time, thus also implying that the latest emerging species will be the one with the highest level of complexity. Since the human species is the last species evolved in the evolutionary process seen at large, this means that we are the species with the highest complexity. The model implies that the human species constitutes an integral part of organic evolution, yet rendering us the exclusive status as the species of the highest complexity. (shrink)

In this article I suggest a view of evolution characterized as a progressive process toward successively higher levels of complexity. In this approach, complexity is defined by means of an operational definition giving the possibility of its measurement by means of a procedure in which development has a crucial role. Furthermore, the concept of competition applied in the complexity space explains the cumulative emergence of new species as well as the presence of stagnant species. In this process, species are formed (...) in a hierarchical order in which the human species is situated on the highest level. This view of evolution, thus also embracing human cultural evolution, is depicted in a diagram of complexity versus time, thus forming a new kind of a Tree of Life. The purpose of the suggested interpretation of evolution is to make it more readily acceptable for common people. (shrink)

This article investigates the rate at different periods of the evolutionary process on Earth. The investigation is based on the author's previous investigations of the growth of evolutionary complexity and on other recent investigations of the rates of scientific evolution and information technology. The measures of the evolutionary rates are given in terms of their doubling times, being several million years for animal evolution, and ranging from a million years to some thousand years for human cultural evolution. After the Galilean (...) scientific revolution the doubling time shows a dramatic drop to about only twenty years and is found to be still shorter for modern information technology. The result shows that the totality of the evolutionary processes on Earth follows a superexponentially increasing rate, characterized by steadily decreasing doubling times. (shrink)

In the present paper I develop a model of the evolutionary process associated to the widespread although controversial notion of a prevailing trend of increasing complexity over time. The model builds on a coupling of evolution to individual developmental programs and introduces an integrated view of evolution implying that human culture and science form a continuous extension of organic evolution. It is formed as a mathematical model that has made possible a quantitative estimation in relative terms of the growth of (...) complexity. This estimation is accomplished by means of computer simulations the result of which indicates a strong acceleration of complexity all the way from the appearance of multicellular organisms up to modern man.
