If you were using cladistics to build a phylogenetic tree of cats, which of the following would be the best outgroup?
a.wolf c.lion
b.domestic cat d.leopard

Respuesta :

Answer: a. Wolf

Explanation:

A phylogenetic tree is a diagrammatic representation in which the premitive living species are compared with the modern organisms on the basis of morphological as well as genetic similarities and differences. Hence, they are separated into distinct groups.

All the given organisms in the options (wolf, domestic cat, lion, and leopard) belong to the vertebrata phyllum. Among the options given all the organisms, except wolf, the other organisms are morphologically close to one other. Thus for constructing a phylogenetic tree for these organisms, wolfs will be an out-group. The other organisms will be the descendent belonging to the same group.

When using cladistics to build a phylogenetic tree of cats, then a WOLF would be the BEST outgroup (Option a).

  • Cladistic is an evolutionary approach to classify taxonomic groups  (i.e., clades) based on the most recent common ancestor of these clades.

  • In cladistics, phylogenetic trees are graphical representations that show lines of evolutionary descent of different clades from a common ancestor.

  • An outgroup is a more distantly related clade that helps to determine the level of evolutionary relationships among organisms or taxonomic groups (e.g., species) within a phylogenetic cladistic tree.

In conclusion, when using cladistics to build a phylogenetic tree of cats, then a WOLF would be the BEST outgroup (Option a).
