Sibley-Ahlquist taxonomy - Wikipedia, the free encyclopedia The Sibley-Ahlquist taxonomy is a radical bird taxonomy based on DNA-DNA hybridization studies conducted in the late 1970s and throughout the 1980s. In fact, the Sibley-Ahlquist taxonomy is merely a highly subdivided hierarchical Linnaean classification; no cladistic methods were used in producing it. Sibley and Ahlquist, though, put penguins in the same superfamily as divers (loons), tubenoses, and frigatebirds; that is, penguins are closer to those birds than herons are to storks. en.wikipedia.org /wiki/Sibley-Ahlquist_taxonomy   (827 words)

You are surfing through the CYBER ANONYMIZER Sibley and Ahlquist's molecular study of the evolution of the bird families has put the radiation of the Procellariiformes in the Oligocene period (35–30 million years ago), though the group has an older history, with a fossil attributed to the order, a seabird known as Tytthostonyx, being found in late Cretaceous rocks (70 mya). This interim taxonomy elevated many established subspecies to full species, but was critisised for not using, in every case, peer reviewed information to justify the splits. The taxonomy of the albatross group has been a source of a great deal of debate. www.goddam.us/nph-cyberanon.cgi/http://en.wikipedia.org/wiki/Albatross   (5556 words)

Wikipedia: Falconiformes Finally, in the influential Sibley-Ahlquist taxonomy, the raptors are all placed in a vastly expanded Ciconiiformes. Falconiforms are known from the Middle Eocene and typically have a sharply hooked beak with a cere (soft mass) on the proximodorsal surface, housing the nostrils. www.factbook.org /wikipedia/en/f/fa/falconiformes.html   (293 words)

List of birds - Wikipedia, the free encyclopedia In particular see Sibley-Ahlquist taxonomy for a very different classification. Taxonomy is very fluid in the age of DNA analysis, so comments are made where appropriate, and all numbers are approximate. This article and the descendant family articles follow the taxonomy of the Handbook of Australian, New Zealand and Antarctic Birds (HANZAB) for families largely endemic to that region, and otherwise the Handbook of Birds of the World (HBW). www.sciencedaily.com /encyclopedia/list_of_birds   (244 words)

Wikipedia: Ciconiiformes Accordingly, the radical and influential Sibley-Ahlquist taxonomy greatly enlarged the Ciconiiformes, adding many more families, including most of those usually regarded as belonging to the Sphenisciformes (penguins), Gaviiformes (diverss). Bird taxonomy has been in a state of flux for some years, and it is reasonable to expect that the large differences between different classification schemes will continue to gradually resolve theselves as more evidence becomes available. Following the development of microbiological research techniques in the late 20th century, in particular methods for studying DNA-DNA hybridisation, a great deal of new information has surfaced, much of it suggesting that many birds, although looking very different to one another, are in fact more closely related than was previously thought. www.factbook.org /wikipedia/en/c/ci/ciconiiformes.html   (678 words)

Sibley House Sibley developed an interest in hybridisation and its implications for evolution and taxonomy and, in the early 1960s he began to focus on molecular studies: of blood proteins, and then the electrophoresis of egg-white proteins. Sibley was elected first as Chairman of the Board of Trustees, and then under the first city charter of 1806 as the first mayor of Detroit. Sibley was instrumental in passing the legislation in 1802 by which Detroit was incorporated as a town. www.artistbooking.com /trips/186/sibley-house.html   (1323 words)

Books Now that avian taxonomy has become a "hot" field, due in large part to the work of Sibley and Ahlquist, I strongly recommend that future revisions be published on CD-ROM disks with the entire updated text avail- able in one place. The answer to both questions is, "Of course not." Many reviews of Distribution and Taxonomy by taxonomists cited a wide range of disagreements, primarily in areas where Monroe had adopted older taxonomy to "flesh out" to the genus and species level, the framework established by Sibley and Ahlquist. For instance, in western North America, Monroe and Sibley re-split Black-crested and Tufted Titmouse, but do not split the Plain Titmouse into California and Rocky Moun- tain species as suggested by Johnston, whose biochemical work indicated that separation be- tween the California and Rocky Mountain forms was much wider than between Black-crested and Tufted Titmouse. elibrary.unm.edu /sora/NABB/v019n01/p0024-p0026.html   (1998 words)

Charadriiformes For an alternative taxonomy, see also Sibley-Ahlquist taxonomy. The Sibley-Alquist taxonomy which has been widely accepted in America, lumps all the Charadriiformes, seabirds and birds of prey into a greatly enlarged Ciconiiformes. This group are the typical shorebirds, most of which feed by probing in the mud or picking items off the surface in both coastal and freshwater environments. www.ebroadcast.com.au /lookup/encyclopedia/ch/Charadriiformes.html   (141 words)

Cuculiformes - Encyclopedia, History, Geography and Biography Sibley-Ahlquist taxonomy raises the Musophagidae to an order Musophagiformes, and the Hoatzin continues to be enigmatic. However, the taxonomy of this group is now controversial. Although the DNA evidence places it with the Cuculiformes, it has structural features inconsistent with that group. www.arikah.net /encyclopedia/Cuculiformes   (91 words)

Hummingbird In the modern Sibley-Ahlquist taxonomy, hummingbirds are separated as a new hummingbird order Trochiliformes. Traditionally hummingbirds were placed in the order Apodiformes, which also contains the swifts. www.black-science.org /wikipedia/h/hu/hummingbird.html   (255 words)

cars - Falconiformes The American Ornithologist's Union leaves Falconidae and Accipitridae in Falconiformes, but places the New World vultures (family Cathartidae) with the storks in Ciconiiformes following the influential Sibley-Ahlquist taxonomy, in which all the raptors are placed into Ciconiiformes, but the Cathartids are considered to be outside the lineage that includes other raptors. However, in Europe, it bas become common to split the order into two: the falcons and caracaras remain in the order Falconiformes (about 60 species in 4 groups), while the remaining 220-odd species (including the Accipitridae—eagles, hawks, and many others) are placed in the separate order Accipitriformes. The idea that Falconiformes should be divided into many orders, is because of the suggestion that the order may not share a single lineage that is exclusive of other birds, and the most controversial suggestion is that Cathartidae are not Falconiformes but are related to the storks, in the separate order, Ciconiiformes. www.carluvers.com /cars/Falconiformes   (366 words)

Sibley and Ahlquist's Phylogeny and Classification of Birds (1990) is a landmark work on the classification of birds (although frequently debated and constantly revised).

Nightjar For more detail and an alternative classification scheme, see Caprimulgiformes and Sibley-Ahlquist taxonomy. In their pioneering DNA-DNA hybridisation work, Sibley and Ahlquist found that the genetic difference between the eared nighjars and the typical nightjars was, in fact, greater than that between the typical nightjars and the nighthawks of the New World. Accordingly, they placed the eared nightjars in a separate family: Eurostopodidae. www.icyclopedia.com /encyclopedia/n/ni/nightjar.html   (360 words)

Kingfishers Fry, Fry and Harris follow the Sibley and Ahlquist (1990) taxonomy at the family level, and thus discuss three separate families of kingfishers [but why their Daceloninae became the Halcyoninae by Woodall (2001), I don't know]. Biochemically, these three groups are distinctive and some (e.g., Sibley and Ahlquist 1990, Sibley and Monroe 1990) have even considered the three groups as three separate families. A lot of authors were quick to adopt Sibley and Ahlquist's revisions lock, stock and barrel. www.montereybay.com /creagrus/kingfishers.html   (2572 words)

Christian Web Site Forum Archive - ChristianWebSite.com Mark's analysis is compelling dissent, and it appears he isn't the only one who is suspicious of Sibley and Ahlquist.... The original findings of Sibley and Ahlquist have been roundly confirmed by more sensitive methods of analysis (theirs was a relatively crude technique, path-breaking at the time, but subsequently superseded by more powerful techniques) According to Powell, "The Sibley work is good science inasmuch as it is repeatable and independently corroborated." Actually, good science is simply carried out competently and honestly. www.botcw.com /talk/archive/index.php/t-11686.html   (18216 words)
