Introduction

Model of Evolutionary Self-development of a Large Ecosystem

The model for the self-development of a large ecosystem

The model for the evolution of ecosystem parameters

The law of biota self-reproduction

General form of the model of evolution of a “transient” population

  • mixed (asexual/sexual) type of reproduction,

  • logistic law of reproduction W,

  • exponentially rational law H of the influence of population density on the average life span of an individual,

  • two evolving parameters C and D,

  • function of adaptability Ffitness = W,

  • influx or migration of live biota from the outside, kin.

Results

Cyclic and intermittent dynamics in the model of evolution of a “transient” population

Global extinction in the history of life as a bistability phenomenon
