This is evident in humans with the genes of fatal diseases; their genes are still in the gene pool even though conditions are unfavorable for their survival. Now that this idea is stuck in our lexicon, there isn't much that can be done to help others understand the actual meaning of the phrase beyond explaining the intended definition of the word "fittest" and the context in which it was said. An alternative could be to avoid using the phrase altogether when discussing the Theory of Evolution or natural selection. It's acceptable for a person to use the term "survival of the fittest" if he or she understands the scientific definition. However, casual use of the phrase by someone without knowledge of natural selection can be misleading.
Students who are first learning about evolution and natural selection should avoid using the term until they have a deeper knowledge of the subject. Share Flipboard Email. Heather Scoville.

The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species. Select from these resources to teach your classroom about this subfield of evolutionary biology. Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
Artificial selection works the same way as natural selection, except that with natural selection it is nature, not human interference, that makes these decisions. Charles Darwin and Alfred Wallace developed the idea of evolution through natural selection. But this idea was not accepted by scientists until more evidence came along. Use this infographic to explore how Darwinism and genetics came together to explain what we know today about evolution. A mutation is a change in the sequence of genetic letters, called bases, within a molecule of DNA.
