| - | '''Speciation''' is the process by which new distinct species evolve in [[Evolutionary System|evolutionary systems]]. A species is a reproductively isolated, independent evolutionary unit. In the course of [[Evolution|evolution]], a lineage of a species can split into two or more. The branching points in the [[Phylogenetic Tree|phylogenetic tree]] mark the speciation events, where a new species emerges. A main reason for speciation in biology is geographical isolation. | + | '''Speciation''' is the process by which new distinct species evolve in [[Evolutionary System|evolutionary systems]].
