What does Phylogeny mean?

What does Phylogeny mean?

• A. The genetic history of an organism
• B. The evolutionary history of an organism
• C. A current snapshot of its behavior
• D. Its lifespan and aging process

Answer: (B)

Phylogeny is the evolutionary history of a species or group, showing how they are related through common ancestry and how lineages have split and diversified over time. It’s what scientists depict with a phylogenetic tree to illustrate which organisms are more closely related and which diverged earlier. This concept isn’t about present behavior or lifespan, and while it uses genetic data, it’s about reconstructing relationships and descent rather than describing the organism’s current state. So the best description is the evolutionary history of an organism.
