“…Although recent molecular investigations revealed that within Aquilinae the genera Spizaetus, Aquila and Hieraaetus as currently defined are paraphyletic groups (Helbig et al, 2005;Lerner and Mindell, 2005;Griffiths et al, 2007;Haring et al, 2007) and, accordingly, several species mentioned in this article should be renamed, a thorough taxonomic revision comprising all representatives of this subfamily is still lacking. Thus, we follow Dickinson (2003) and use the conventional names in this article (also concerning orders, families and subfamilies).…”

Repeated sequence homogenization between the control and pseudo‐control regions in the mitochondrial genomes of the subfamily Aquilinae

In birds, the noncoding control region (CR) and its flanking genes are the only parts of the mitochondrial (mt) genome that have been modified by intragenomic rearrangements. In raptors, two noncoding regions are present: the CR has shifted to a new position with respect to the ''ancestral avian gene order,'' whereas the pseudo-control region (CCR) is located at the original genomic position of the CR. As possible mechanisms for this rearrangement, duplication and transposition have been considered. During characterization of the mt gene order in Bonelli's eagle Hieraaetus fasciatus, we detected intragenomic sequence similarity between the two regions supporting the duplication hypothesis. We performed intra-and intergenomic sequence comparisons in H. fasciatus and other falconiform species to trace the evolution of the noncoding mtDNA regions in Falconiformes. We identified sections displaying different levels of similarity between the CR and CCR. On the basis of phylogenetic analyses, we outline an evolutionary scenario of the underlying mutation events involving duplication and homogenization processes followed by sporadic deletions. Apparently, homogenization may easily occur if sufficient sequence similarity between the CR and CCR exists. Moreover, homogenization itself allows perpetuation of this continued equalization, unless this process is stopped by deletion. The Pandionidae and the Aquilinae seem to be the only two lineages of Falconiformes where homology between both regions is still detectable, whereas in other raptors no similarity was found so far. In these two lineages, the process of sequence degeneration may have slowed down by homogenization events retaining high sequence similarity at least in some sections.In contrast to the nuclear genome, where duplications and rearrangements are an important driving force of genome evolution, the mitochondrial (mt) genome of vertebrates has a more or less conserved structure. Nevertheless, modifications and rearrangements were detected in several groups of vertebrates. For example, the exchange of the positions of tRNA genes has been found in marsupials (Pääbo et al., '91),

“…Recent DNA studies suggest that these two genera in the traditional sense are paraphyletic, with some Hieraaetus species more closely related to Aquila and vice versa (Wink and Sauer-Gü rth 2004, Helbig et al 2005, Lerner and Mindell 2005. The two genera may either be merged, or some species may be transferred between the two genera, with the Wedge-tailed Eagle in Aquila and the Little Eagle remaining in a more circumscribed Hieraaetus (Helbig et al 2005, Debus et al 2007a.…”

“…Comparisons of the specimen were made with Australian and extralimital species of these genera and of Hieraaetus, sister genus to Aquila and also represented in Australia. Lerner & Mindell (2005) and Helbig et al (2005) found that Aquila and Hieraaetus, as conventionally circumscribed, were polyphyletic relative to each other. Some authors (e.g., Sangster et al, 2005) synonymized the two genera.…”

aBstract. A large accipitrine bird of prey is described from the Mid Miocene Camfield Beds, Bullock Creek, Northern Territory, Australia, based on a distal humeral fragment. Comparisons with the larger living Australian eagles show that this bird belongs in Aquila rather than Haliaeetus. It can be differentiated from living species of Aquila by morphology and size, and is here named as a new fossil species. This specimen comprises the oldest record of this genus in Australia, and possibly the oldest in the world.
