This human ancestor phylogenetic tree is a graphical representation of the evolutionary relationship between different taxa—the phylogenetic tree, including reconstruction and verification. The terms evolutionary tree and cladogram are frequently used interchangeably to refer to the same thing: the evolutionary relationships between taxa. Although there are subtle differences, as shown in this human ancestor phylogenetic tree diagram, the terms dendrogram and cladogram are used interchangeably. Phylogenetic trees are mathematical structures that summarize the most recent common ancestor relationships among a group of organisms. Download EdrawMax and create useful phylogenetic trees today.
