=== Horizontal gene transfer ===
Horizontal gene transfer is the mobility of genetic info between different organisms that can have immediate or delayed effects for the reciprocal host.<ref>{{Cite journal |last1=Emamalipour |first1=Melissa |last2=Seidi |first2=Khaled |last3=Zununi Vahed |first3=Sepideh |last4=Jahanban-Esfahlan |first4=Ali |last5=Jaymand |first5=Mehdi |last6=Majdi |first6=Hasan |last7=Amoozgar |first7=Zohreh |last8=Chitkushev |first8=L.

This does typically not directly interfere with ancestry of the organism, but can complicate the determination of that ancestry. On another level, one can map the horizontal gene transfer processes, by determining the phylogeny of the individual genes using cladistics.
