Phylogenetic means organisms related by evolutionary history.

Phylogenetic means organisms related by evolutionary history.

• A. Evolutionary history
• B. Taxonomy
• C. Organisms related by evolutionary history
• D. Similar function or form

Answer: (C)

Phylogenetic describes the relationships among living things based on their evolutionary history. It comes from phylogeny, the branching pattern of descent from common ancestors. So the best way to capture its meaning is that it refers to organisms related by evolutionary history—their shared ancestry and how they diverged over time. This focus on relationships through time is what sets phylogeny apart from simply noting history itself, from taxonomy (which is about naming and grouping), or from looking at similarities in function or form that might arise for other reasons. In practice, scientists use genetic data and shared derived traits to build trees that show which species are more closely related and when their lineages split. For example, humans and chimpanzees are closer to each other on the evolutionary family tree than either is to more distant primates, reflecting their more recent common ancestor.
