The evolutionary history and relationship of an organism or group of organisms is called its phylogeny. A phylogenetic tree, also known as a "Tree of Life" or "Dendrogram", is a diagram that shows the evolutionary relationships between living organisms. It depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor. The tree of life starts with the three main branches of the phylogenetic tree: bacteria, archaea, and eukarya. Phylogeny is the study of the organisms with respect to its evolution and the relationship with other organisms. It...

The tree of life starts with the three main branches of the phylogenetic tree: bacteria, archaea, and eukarya. Phylogeny is the study of the organisms with respect to its evolution and the relationship with other organisms. It helps in identifying the organisms and the ancestral relatives and the history of these organisms by creating a phylogenetic tree. Phylogenetic trees are hypotheses, not definitive facts. The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors.
