What does evolution talk about?
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
When evolution occurs at a slow constant rate with periods of rapid change it is known as?

What is it called when evolution occurs rapidly?
When geologic and climatic conditions are changing, evolution may occur more quickly. Thus, long periods of little change may be interrupted by bursts of rapid change. This model of the timing of evolution is called punctuated equilibrium. It is better supported by the fossil record than is gradualism.

What is evolution process?

Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species. An example of macroevolution is the evolution of a new species. …

What type of evolution occurs gradually and slowly over a long period of time?
Phyletic gradualism is one theory of evolution that tries to model this rate. It predicts that species are always gradually evolving, changing very slowly over time.
