Topic: Charles Sibley


  
  Charles Sibley - Wikipedia, the free encyclopedia
Charles Gald Sibley (August 7, 1917 - April 12, 1998) was an American ornithologist and molecular biologist.
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.
By the early 1970s Sibley was pioneering DNA-DNA hybridisation studies, with the aim of discovering, once and for all, the true relationships between the modern orders of birds.

Charles Sibley (August 7, 1917 - April 12, 1998) was an American ornithologist and molecular biologist.
But by the mid to late 1980s, Sibley's ongoing work had reversed the trend.
In 1990 Sibley was elected President of the International Ornithological Congress.

 In Memoriam
Charles Sibley was born August 7, 1917, in Fresno, California.
With Jon Ahlquist, Charles Sibley was one of the pioneers in applying this technique to study taxonomical relationships in birds.
After Monroe died in 1994, Charles Sibley continued to publish revisions to this classification in his computerized book, Birds of the World (of which version 2.0 is reviewed elsewhere in the same issue of Dutch Birding).

 Charles Gald Sibley, August 7, 1917–April 12, 1998 | By Alan H. Brush | Biographical Memoirs
In addition to his AOU activities Charles was a secretary of the Cooper Ornithological Society, a fellow or corresponding fellow of six foreign societies, and an officer or council member of five societies.
In 1988 Charles and colleague Jon E. Ahlquist received the Daniel Giraud Elliot Medal from the National Academy of Sciences in recognition of their contributions to our knowledge of avian systematics, and in 1991 Charles was awarded the Alessandro Ghigi Medal by the National Institute of Wildlife Biology (Italy).
By 1974 Charles was already a decade and a half into the taxonomic comparison of the egg-white proteins.The early electrophoretic methods for the separations of proteins on paper strips soon became obsolete.

 Charles Sibley - EvoWiki   (Site not responding. Last check: 2007-10-07)
Sibley pioneered the use of DNA-DNA hybridization methods and used it to map out a molecular phylogeny of Aves, which was presented with Jon Ahlquist in 1990, and is arguably the greatest of Sibley's contributions to ornithology.
Sibley and Ahlquist's molecular phylogeny represented one of the most authoritative and rigorous phylogenetic analyses of extant birds ever carried out, and though highly contentious, the data presented therein has been crucial to rethinking the evolutionary relationships of birds.
Sibley and Ahlquist were also the first formalize the phylogeny of primates, showing that chimps were more closely related to humans than to gorillas.

 Sibley-Ahlquist taxonomy - Wikipedia, the free encyclopedia
For instance, instead of putting the swifts, treeswifts, and hummingbirds in the same order that includes nothing else, Sibley and Ahlquist put them in the same superorder that includes nothing else, consisting of one order for the hummingbirds and another for the swifts and treeswifts.
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.

In 1990, Charles Sibley and Jon Ahlquist published the results of their DNA studies, substantially revising the taxonomy of the world's birds.
Sibley has been in the forefront of these changes, logging them in almost as fast as the relevant studies appear in the literature.
Because Sibley is so closely in touch with the literature and has a world-wide network of correspondents, these changes get incorporated into BOW almost as soon as they appear in the scientific journals, and generally well before scientific bodies like the AOU ratify them.

Evolutionists Charles Sibley and Jon Ahlquist have been comparing the DNA (the molecules that encode the genetic information) of different birds.
Sibley and Ahlquist then determine how much they must heat the DNA to melt the hybrid molecules that have formed.
Sibley and Ahlquist's tens of thousands of DNA-DNA hybrid comparisons have revealed that each of two close relatives, say, a mockingbird and a thrasher, show the same genetic distance from a third less-related bird.

 Essay Review of Sibley and Ahlquist's "Phylogeny and Classification of Birds"
Sibley and Ahlquist regularly resolve branches that are only a fraction of a degree apart, but the work of their critics suggests that such resolutions are unlikely to be reliable.
In their earlier publications, Sibley and Ahlquist assumed that there was a uniform average rate of DNA evolution in all lineages.
Sibley and Ahlquist believe this accounts for the anomaly of Turnix, a rapid breeder, which is exceptionally distant in genetic terms from all other avian taxa.

 Science News: Where do storks come from, mommy? - system of classifying birds by similarities in their genetic material
Over the last 10 years, Charles G. Sibley and John E. Ahlquist of Yale University have developed a system of classifying birds by the similarities in their genetic material.
The bird family tree proposed by Sibley and Ahlquist disagrees in several of its branches with previous classifications based on the anatomical similarities, but it fits well with geological data, Sibley says.
Sibley says, "This correlates with the belief that the two species evolved from a common ancestor that lived in northern Canada and Greenland until temperatures cooled about 25 million years ago and forced birds and animals south to Europe and America.'

 Silky-Flycatchers
Although the silky-flycatchers are a distinctive group, DNA hybridization evidence (e.g., in Sibley and Ahlquist 1990) indicates that they are most closely related to waxwings.
Indeed, Sibley and Monroe (1990), Sibley (1996), and Clements (1991) all lump them together in one family with the waxwings, and the expanded group takes the waxwing family name [Bombycillidae].
Sibley worked with egg-white proteins before moving to the DNA-DNA hybridization technique.
