Emilie Knight · Answer 1

Rooted trees shows the most basal ancestor of the tree. Unrooted phylogenetic tree does not show an ancestral root.

Rohan · Answer 2

In a phylogenetic tree, every node represents a species ... A rooted tree is a tree in which one of the nodes is stipulated to be the root, and thus the direction of ancestral relationships is determined. An unrooted tree, as could be imagined, has no pre-determined root and therefore induces no hierarchy.
