[Taxacom] incorrect topology

In a paper by Glazko and Nei (2003: Molecular biology and evolution 20:
424-34) the authors state (p. 425) that a NJ tree was constructed for
each gene that "eliminated all the genes that produced the incorrect
topology except for humans, chimpanzees, and gorillas" Since the only
other taxa were orangutans, an artiodactyl, a mouse, and a rat, one
might wonder if they found topologies that supported a human-orangutan
relationship but because this was 'wrong' it was eliminated. I'll see if
I can get an answer out of the authors, but the problematic aspect of
this statement is that the 'wrong' topologies were never identified.
