Which of the following is true about these three species? All three species should be classified within the same genus. All three species evolved over time to best fit unique environments. All three species have not adapted since their existence.

The statement that is true about the three species is: **"All three species share a distant common ancestor."** This is a common principle in evolutionary biology, where different species share a common ancestor in the course of their evolution. The other statements may not hold true universally; for example, the species might not be in the same genus, and while some species may have evolved to fit unique environments, it is unlikely that they have not adapted at all since their existence.
