phylogenetic species concept
The Phylogenetic Species Concept defines a species based on its evolutionary history and genetic relationships. It focuses on identifying groups of organisms that share a common ancestor and exhibit distinct characteristics that set them apart from other groups. Essentially, it classifies species based on a "family tree" of life, showing how different organisms are related through evolution. This concept helps scientists understand biodiversity by emphasizing not just physical traits but also the genetic and historical connections among species.

The phylogenetic species concept defines a species as the smallest group of organisms that share a common ancestor and can be distinguished from other such groups based on genetic, morphological, or evolutionary traits. This approach emphasizes the evolutionary relationships among organisms, looking at their shared history rather than solely physical characteristics. In essence, it aims to identify species based on their lineage and the unique traits that result from their evolutionary path, helping scientists understand biodiversity and how different species are related through evolution.
