Therefore, he called this type of selection natural selection. Darwin knew artificial selection could change domestic species over time. He inferred that natural selection could also change species over time. In fact, he thought that if a species changed enough, it might evolve into a new species.

Second, more offspring are produced than are able to survive; in other words, resources for survival and reproduction are limited.Study with Quizlet and memorize flashcards containing terms like Why is heritability important for both natural and artificial selection?, Natural selection is based on four main principles: variation, overproduction, adaptation, and descent with modification.

Along with cognitive psychologists, evolutionary psychologists propose that much, if not all, of our behavior can be explained by appeal to internal psychological mechanisms.

Natural selection is based on four main principles: variation, overproduction, adaptation and descent with modification. Briefly explain how each of these principles is necessary for natural selection to occur. Variation = natural variation in genetic code, due to mutations. Without this, change would never occur.
