How can you explain the diversity of living organisms on our planet?

The huge diversity of species on our planet is explained by the various existing biogeocenoses, in which conditions differ from each other. This gives rise to a change in the genetic heritage of living systems inhabiting the designated area. The difference in climatic factors, nutrition, natural enemies leads to the fact that organisms have different adaptations to life – adaptations. An individual with new traits, especially if they are useful and have adaptive and selective value, multiplies and gives birth to offspring with a phenotype and genotype that was not there before.
