Detailed explanation-1: -Both phylogenetic trees and cladograms help show the relationships between different organisms, but only phylogenetic trees have branches that represent evolutionary time and amount of change.
Detailed explanation-2: -A phylogenetic tree may not indicate how much time passed between the evolution of amniotic eggs and hair. What the tree does show is the order in which things took place.
Detailed explanation-3: -In the context of molecular phylogenetics, the expressions phylogenetic tree, phylogram, cladogram, and dendrogram are used interchangeably to mean the same thing-that is, a branching tree structure that represents the evolutionary relationships among the taxa (OTUs), which are gene/protein sequences.
Detailed explanation-4: -The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors. In trees, two species are more related if they have a more recent common ancestor and less related if they have a less recent common ancestor.
