Although phylogenetic trees produced on the basis of sequenced [[gene]]s or [[genome|genomic]] data in different species can provide evolutionary insight, they have important limitations. They do not necessarily accurately represent the evolutionary history of the included taxa. The data on which they are based is [[signal noise|noisy]]; the analysis can be confounded by [[genetic recombination]],<ref name=Arenas_2010>{{cite journal |author=Arenas M, Posada D |title=The effect of recombination on the reconstruction of ancestral sequences |journal=Genetics |volume=184 |issue=4 |pages=1133–1139 |year=2010 |doi=10.1534/genetics.109.113423 }}</ref> [[horizontal gene transfer]],<ref name=Woese_2002>{{cite journal |author=Woese C |title=On the evolution of cells |journal=Proc Natl Acad Sci USA |volume=99 |issue=13 |pages=8742–7 |year=2002 |pmid=12077305 |doi=10.1073/pnas.132266999 |pmc=124369|bibcode = 2002PNAS...99.8742W }}</ref> [[Hybrid (biology)|hybrid]]isation between species that were not nearest neighbors on the tree before hybridisation takes place, [[convergent evolution]], and [[conserved sequence]]s.
