Julia is trying to place a duckbilled platypus, lizard, bear, and monkey on a phylogenetic tree. she learns that the duckbilled playpus, bear, and monkey are classified as mammals. she also learns that mammals share a common ancestor with reptiles. which additional piece of information will be most to julia to properly build her phylogenetic tree?

The correct answer for the question that is being presented above is this one: "the mammal and the reptile." The additional piece of information will be most helpful to Julia to properly build her phylogenetic tree is that it is trying to figure out on what tree it belongs to but it has some features of the animals but the 2 main ones: the mammal and the reptile.
