Phylogenetic species concept Notes:
This concept of a species describes species as an irreducible group whose members are descended from a common ancestor and who all possess a combination of certain defining, or derived, traits. Hence, this concept defines a species as a group having a shared and unique evolutionary history. With this concept the breeding between members of different species does not pose a problem. Also, it permits successive species to be defined even if they have evolved in an unbroken line of descent, with continuity of sexual fertility.
