What are the principles of natural selection?

For natural selection to occur, four basic conditions are necessary:

​​

  • 1) Reproduction: organisms must reproduce to form new generations;
  • 2) Variability: there must be differences between individuals in the population;
  • 3) Heredity: Descendants must inherit characteristics from their parents.

Natural selection is the evolutionary mechanism proposed by Charles Darwin, who stated that the environment acts as a selector of characteristics, perpetuating the organisms best able to survive in a given place.
