We discuss the evolutionary significance of four aberrant 18S rDNA clones
that were obtained from human, chimpanzee, and gorilla DNA libraries. We
show that these clones carry representatives of a small 18S rDNA pseudogene
family that arose in a common ancestor of these species. Aspects of their
structure and phylogenetic distribution suggest that the 18S pseudogenes no
longer interact genetically with normal ribosomal genes and therefore may
not be linked to nucleolus organizer regions.
