{{Image|Phylogenetic Tree of life SVG.svg|left|600px|A phylogenetic tree of [[life]], showing the relationship between [[species (biology)|species]] whose [[genomes]] have been [[Genome project|mapped]] by humans. The very center represents the [[last universal ancestor]] of all [[life]] on [[earth]]. The different colors represent the three [[domain (biology)|domains of life]]: pink represents [[eukaryota]] (animals and plants); blue represents [[bacteria]]; and green represents [[archaea]]. Our species ([[Homo sapiens]]) is second from the rightmost edge of the pink segment. The light and dark bands along the edge correspond to clades: the rightmost light red band is [[Metazoa]], with dark red [[Ascomycota]] to its left, and light blue [[Firmicutes]] to its right.}} 
{{Image|Labrid fish phylogenetic tree.png|right|350px|[[Phylogenetic]] relationships among the [[Labroid]] [[family (biology)|families]] of [[fish]], based on whole [[mitochondrial DNA]] [[DNA sequence|sequences]]. Note that the species of the [[Labridae]] and those of the remaining three labroid families ([[Cichlidae]], [[Pomacentridae]], and [[Embiotocidae]]) form different [[monophyletic group]]s, respectively.}}
