Line 45:
The genealogical hierarchy exist as a consequence of the spatial distribution of reproduction in species. The levels within the hierarchy ascend with increasing size and geographic range, and are each subjected to corresponding factors in the ecological hierarchy.<ref name=":1">{{Cite journal|last=Eldredge|first=Niles|date=2007-11-21|title=Hierarchies and the Sloshing Bucket: Toward the Unification of Evolutionary Biology|journal=Evolution: Education and Outreach|volume=1|issue=1|pages=10–15|doi=10.1007/s12052-007-0007-6|issn=1936-6426|doi-access=free}}</ref>
 
The lowest level in the genealogical hierarchy is the organism, specially in its reproductive sense. These organism participate the reproduction of the overall species. The next level up in the hierarchy are '[[Deme (biology)|deme]]' who are the interbreeding local population of a species. These can be thought of as specific regional variations of the species that interbreed. The next and second highest level in the hierarchy are [[species]]. The final and highest level in the genealogical hierarchy are [[Monophyly|monophyletic taxa]], who all share and come from ana common ancestor.
