Detailed explanation-1: -In a phylogenetic tree, the species of interest are shown at the tips of the tree’s branches. The branches themselves connect up in a way that represents the evolutionary history of the species-that is, how we think they evolved from a common ancestor through a series of divergence (splitting-in-two) events.

Detailed explanation-2: -Branches show the path of transmission of genetic information from one generation to the next. Branch lengths indicate genetic change i.e. the longer the branch, the more genetic change (or divergence) has occurred.

Detailed explanation-3: -The root node represents the most recent common ancestor of all of the taxa represented on the tree. Time is also represented, proceeding from the oldest at the bottom to the most recent at the top.

Detailed explanation-4: -Most phylogenetic trees are rooted, meaning that one branch (which is usually unlabeled) corresponds to the common ancestor of all the species included in the tree.
