The beta h3 pseudogene of the BALB/c mouse contains sequence defects which prevent transcription and translation to produce a beta-globin. Comparison with other globin gene sequences indicates that beta h3 arose by recombination between an adult beta-globin gene and some significantly diverged globin sequence. Analysis of noncoding sequences shows that the 3' end of mouse beta h3 and the human delta-globin gene are both descended from an ancestral gene, which we call proto-delta. The origin of proto-delta must predate the mammalian radiation. A member of the L1 family of interspersed repetitive elements is inserted into the 3' untranslated delta-homologous sequence in beta h3 from BALB/c. beta h3 is a widespread feature of the rodent beta-globin complex, which has been fixed in the genome for 35 million years. Independent inactivation events produced pseudogenes located between the adult and nonadult beta-globin genes in the rodent, primate, rabbit, and goat lineages. One model to explain the abundance and evolutionary persistence of pseudogenes postulates that the mammalian genome simply has no efficient mechanism for deleting nonessential sequences. Consequently, the genomes of higher eukaryotes have been growing, by the accumulation of duplications, with doubling times of 200 +/- 100 million years.
