A biological process tree or organic process tree may be a branching diagram or "tree" showing the inferred organic process relationships among numerous biological species or alternative entities primarily based upon similarities and variations in their physical and/or genetic characteristics. The taxa joined along within the tree square measure tacit to own descended from a typical relative. In an exceedingly stock-still biological process tree, every node with descendants represents the inferred most up-to-date common relative of the descendants, and also the edge lengths in some trees is also taken as time estimates every node is named a categorization unit. Internal nodes square measure usually known as theoretical categorization units, as they cannot be directly determined. Trees square measure helpful in fields of biology like bioinformatics, science, and comparative phylogenetics.
