On the tree above circle a monophyletic group with 2 or more

On the tree above, circle a monophyletic group (with 2 or more taxa), a paraphyletic group, and a polyphyletic group. Be sure to label your groups on the tree and explain how you made your groupings. Use 3 different colors to circle the three different types of groups or otherwise clearly identify circled groups as mono-, para-, or polyphyletic.

Solution

Taxon or a group which are having the common ancestor is called Monophyletic Group here Whale and Hippopotamus are Monophyletic . They belongs to the same order Cetartiodactyla.Both are semi aquatic.

Polyphyletic taxon is the group in which there would be no common ancestor. here Horse and Giraffee are polyphyletic with out having a common ancetor.

Paraphyletic group is the one which have resemblance with the monophyletic group but differs in some of the characters . They are placed separately in a clade. Here seal is placed under different clade pinnidae which means that it is paraphyletic.
