Phyletic lineage refers to the evolutionary lineage or ancestral line of descent of a particular organism or group of organisms. It traces the evolutionary history and relationships between different species over time.
Biodiversity refers to the variety of life forms on Earth, encompassing the diversity of species, ecosystems, and genetic diversity within species. It's crucial

Phyletic lineages, or evolutionary lineages, play a vital role in biodiversity by tracing the evolutionary history of organisms over time. Understanding these lineages helps scientists comprehend the relationships between species, how they've evolved, and how they're interconnected within ecosystems. It's fundamental for conservation efforts, evolutionary biology, and understanding the dynamics of life on Earth.
