What is phylogeny?

What is phylogeny?

• A. A behavior change tactic using positive punishment
• B. The history of the natural evolution of a species
• C. A method of time sampling
• D. A relation between stimulus and response

Answer: (B)

Phylogeny refers to the history of the natural evolution of a species. It covers the inherited traits and behaviors that have developed over many generations through natural selection, not what an individual learns or experiences in its own life. This is different from ontogeny, which is how a single organism grows and develops, including learned behaviors. So the best answer describes the evolutionary history of a species. The other options describe a behavior-change tactic, a data-collection method, or a stimulus–response relationship, none of which capture evolutionary history.
