They focused only on the ribosomal RNA gene, disregarding genetic material that might have been acquired more recently by symbiosis or lateral gene transfer. Lateral gene transfer occurs when organisms acquire genes from other organisms in their environment, rather than inherit them.
In the case of bacteria, lateral gene transfer has been considered to be so widespread that it renders the concept of species among bacteria meaningless and makes it impossible to construct an evolutionary tree.
This possibility has gained interest since biologists found that bacteria, with surprising frequency, exchange genes with each other through a process called lateral gene transfer (SN: 7/22/00, p.
This lateral gene transfer would not have occurred recently, because the Fe-hydrogenases of entamoebas and giardias showed only a 40% amino acid identity with each other, and each fe-hydrogenase gene has the codon usage of its host.

"It's an interesting case of Lateral Gene Transfer, or the movement of genes between distantly related species," said Patrick Keeling, a University of British Columbia botany professor and one of the study's authors.
In fact, a recent article on horizontal or lateral gene transfer cites Lederberg and Tatum's 1946 paper as its first reference (McInerney & Pisani, 2007).
