The article analyses the concepts and model of social evolution. The most important concepts of biological evolution (mutation, selection, evolution, micro-evolution, selective pressure, environment of evolutionary adaptation, evolutionary stable strategy) are taken for granted and adapted to describe some important phenomena of sociology, with their necessary adaptation to social 'institutions'. The article argues that in sociology one should use the concept of evolution as precisely as in biology. It analyses certain similarities and important differences of the two types of the evolutionary processes: the Darwinian and the Lamarckian ones. Based on the proposed concept of social evolution, it outlines the model and contour of evolutionary sociology.
