The science of the geneticist found independence a little more than 100 years ago and began with studying hybrid life forms. In the center of consideration of modern genetics there are two fundamental properties of living organisms – heredity and variability. The methods used by scientists-geneticists allow to answer the important questions directly related to evolution of living organisms.
The ecology is a science about studying ecosystems. The ecological equilibrium in various dictionaries is defined as "a condition of dynamic balance in community of organisms in which a genetic, species and ecosystem diversity remain rather stable, are subject to gradual changes in the course of natural inheritance" or "stable equilibrium of number of each look in an ecosystem".
