What Are Some Misconceptions About Natural Selection

Natural selection involves organisms trying to adapt. Natural selection gives organisms what they need. Humans can’t negatively impact ecosystems, because species will just evolve what they need to survive. Natural selection acts for the good of the species.

What is a bad thing about natural selection?

If negative selection is too strong for the whole population, extinction will occur, unless the population is rescued in time. Extinction can occur if the negative selection considered is “hard” selection, which actually reduces the number of surviving offspring that are produced.

Why is natural selection not the same as evolution?

Evolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
