Choose the best explanation of the difference between evolution and natural selection. a. natural selection is the idea that species change over time, and evolution is the idea that our world changes over time. b. evolution is the idea that species change over time, and natural selection is the idea that nature changes over time. c. natural selection is the idea that species change over time, and evolution is the idea that the species' food source also changes over time. d. evolution is the idea that species change over time, and natural selection is a mechanism by which evolution takes place.

The correct answer is D. Evolution is the idea that species change over time, and natural selection is a mechanism by which evolution takes place.

Explanation:

In biology, the word "evolution" refers to  the changes in terms of genes (Genotype) and observable traits (phenotype) species undergo over time or through successive generations that led to changes within species but also to the emergence of new species as the result of mutations, genes changing or event genes being combines. On the other hand, the natural selection is one of the main mechanism that explain evolution, because natural selection refers to the prevalence of certain features that support survival and reproduction and that because of these are inherited which means those traits remain while other traits that are not favorable disappear over time which implies changes in species or evolution.  Therefore, the statement that shows the difference between evolution and natural selection is "Evolution is the idea that species change over time, and natural selection is a mechanism by which evolution takes place".
