What kinds of adaptive evolution are its driving forces?

The driving forces of evolution are changes during which an organism can change its structure due to changing environmental conditions. Changes can be both positive and negative. The main driving forces are:

– idioadaptation – the body changes its phenotypic characteristics under the influence of certain factors;

– natural selection – stronger and more adapted individuals remain in the course of this selection and continue their offspring;

– the struggle for existence – there is an interspecific struggle, a struggle within one species for food and females, a struggle against negative environmental conditions.
