WebRather, Eukaryotic genes present in bacterial and archaeal organisms are hypothesized to be from horizontal transfer from an early ancestor of modern eukaryotes. This putative ancestor possessed crucial "starter" genes that enabled increased cellular complexity. This common ancestor, or a relative, eventually led to the evolution of eukaryotes. WebAs such, if Eukarya descend from Archaea, this last group becomes paraphyletic and offers the possible identification of the FECA (First Eukaryotic Common Ancestor),i.e. the oldest branching point at which the eukaryote lineage and its closest extant relatives separated.
