Whether clades with few living species may be very young. Introduction: A group of organisms that have been originated and evolved from one common ancestor is called a clade. The variation occurred due to the evolution of a common ancestor to adapt and diversify into one or more species and subgroups. Since the origin is same, clade is said to be monophyletic. The construction of a phylogenetic tree helps to observe clades.

It is possible for two different genes to imply different phylogenetic relationships among a group of species. What are the possible reasons for this? If there is only one true history of formation of these species, what might we do in order to determine which (if either) gene accurately portrays that history? Is it possible for both phylogenetic trees to be accurate even if there has been only one history of species divergence?

n which situation would it make sense to use the phylogenetic species concept? When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive data When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed When you only have genetic data about each organism in your study When working with fossils from extinct organisms

Currently, two of the extant porpoise species (Y and Z) are placed in the genus Tursiops, and a third species (X) is placed in the genus Delphinus. Assuming this classification reflects evolutionary relatedness, which of the following is the most accurate phylogenetic tree? d O C OB OA OD
