This convergence may have been facilitated by the fact that many potential evolutionary pathways to a C4 phenotype exist, many of which involve initial evolutionary steps not directly related to photosynthesis.
Esta converxencia puido ser facilitada porque existen moitas vías evolutivas potenciais para que apareza o fenotipo C4, moitas das cales implican pasos evolutivos iniciais non directamente relacionadas coa fotosíntese.
