The hierofalcons are four closely related species of falcon which make up the subgenus Hierofalco: Lanner falcon, Falco biarmicus Laggar falcon, Falco jugger Saker falcon, Falco cherrug Gyrfalcon, Falco rusticolus The black falcon of Australia is occasionally considered allied to the hierofalcons: indeed it seems fairly close to them (Wink et al. 2004). They represent members of their genus which are similar to species like the peregrine falcon in outward appearance, but usually with more phaeomelanins which impart reddish or brown colors, and generally more strongly patterned plumage reminiscent of hawks. Their undersides usually have a lengthwise pattern of dark blotches, lines or arrowhead marks. They hunt usually in level flight, more like Accipiters than peregrines with their dive attack or hobbies with their acrobatic pursuits. Recent DNA sequence data studies have confirmed that the hierofalcons are a monophyletic group—and, incidentally, that hybridization runs rampant in the present species complex. Initial results of mtDNA cytochrome b sequence analyses that suggested they are basal among all living falcons were in error, due to a numt (Wink & Sauer-Gürth 2000). The biogeographically entirely distinct prairie falcon was sometimes placed with the hierofalcons due to its similar coloration; it is now considered not to belong in this subgenus, the similarities being the result of convergent evolution in adaptation to similar habitat. The hierofalcon lineage as such seems of Late Pliocene origin, maybe as old as the "typical" kestrels (Gelasian, some 2.5–2 million years ago), maybe somewhat older, though little is known about their fossil history. It seems to have originated in Africa or adjacent regions but apparently became nearly extinct in the past: the present hierofalcon diversity is of rather recent origin, presumably not older than the Eemian interglacial (about 130,000–115,000 years ago) at the start of the Late Pleistocene; only one of the hierofalcon species that presumably diverged between the Pliocene and the Middle Pleistocene has left any living descendants.

Prairie falcon

The prairie falcon (Falco mexicanus) is a medium-large sized falcon of western North America. It is about the size of a peregrine falcon or a crow, with an average length of 40 cm (16 in), wingspan of approximately 1 meter (40 in), and average weight of 720 g (1.6 lb). As in all falcons, females are noticeably bigger than males. Though a separate species from the peregrine, the prairie falcon is basically an arid environment divergence of the early peregrine falcon lineage, able to subsist on less food than the peregrine, and generally lighter in weight than a peregrine of similar wing span.

Gyrfalcon

The gyrfalcon (ˈdʒɜrˌfɔː(l)kən or ˈdʒɜrˌfælkən) (), the largest of the falcon species, is a bird of prey. The abbreviation gyr is also used. It breeds on Arctic coasts and tundra, and the islands of northern North America and the Eurosiberian region. It is mainly a resident there also, but some gyrfalcons disperse more widely after the breeding season, or in winter. Individual vagrancy can take birds for long distances. Its plumage varies with location, with birds being coloured from all-white to dark brown.

Lanner falcon

The lanner falcon (Falco biarmicus) is a medium-sized bird of prey that breeds in Africa, southeast Europe and just into Asia. It prefers open habitat and is mainly resident, but some birds disperse more widely after the breeding season. A large falcon, it preys on birds and bats. Most likely either the lanner or peregrine falcon was the sacred species of falcon to the ancient Egyptians, and some ancient Egyptian deities, like Ra and Horus, were often represented as a man with the head of a lanner falcon.

Reanalysis of mtDNA mutations of human primordial germ cells (PGCs) reveals NUMT contamination and suggests that selection in PGCs may be positive

Konstantin Popadin

The resilience of the mitochondrial genome (mtDNA) to a high mutational pressure depends, in part, on negative purifying selection in the germline. A paradigm in the field has been that such selection, at least in part, takes place in primordial germ cells ...
