Answer

Brief Explanations:

A phylogenetic tree shows evolutionary relationships. Since mammals share a common ancestor with reptiles and we know platypus is a mammal, information about its reptile - like trait (laying eggs) helps in building the tree by highlighting its ancestral - like characteristics.

Answer:

The platypus lays eggs like a reptile.
