Topic: Darwins finches


  
  Charles Darwin
After Darwin finished his studies, Henslow recommended him for the position of naturalist and gentleman's companion to Robert Fitzroy, the captain of the HMS Beagle, which was departing on a five-year expedition to chart the coastline of South America.
Darwin died in Downe, Kent, England, on 19 April 1882 was given a state funeral, and interred in Westminster Abbey near Isaac Newton.
Darwin is included in the top 10 of the 100 Greatest Britons poll sponsored by the BBC and voted for by the public.

 Darwin's Finches
Today Darwin's finches are the subject of intense study, and they are revealing much about the evolutionary process.
Among the Darwin's finches, there is general agreement as to the existence of 13 Galapagos species, although there may be one or two more or one or two less, depending on how one assesses several unusual populations.
As a group, the tree finches are more heterogeneous than the ground finches and it is current practice to subdivide the tree finches into three genera: Camarhynchus (the tree finches), Platyspiza (the vegetarian finch) and Cactospiza (the woodpecker and mangrove finches).

 Charles Darwin
Charles Darwin himself did not actively defend his theories; he was constantly in ill health, and Huxley was skilled enough to handle the situation for him.
Darwin was given particular recognition in 2000 when his image appeared on the Bank of England ten pound note, replacing Charles Dickens.
Darwin's theory is now backed up by the comparison of DNA from different organisms which shows the closeness of their relationship.

Darwins Finches: The idea of evolution is not new, but when Darwin suggested it after his death, mostly to save his own head, it was a large revelation in the scientific community and amongst religious circles.
What Darwin had discovered was that on one of the main islands there was one type of finch, yet just across the short channel there was a completely different set, but each of the birds sharing some characteristics, su ggesting that they had come from one descendent.
When Darwin studied the finches he did not consider the whole island and his surveys were patchy to say the least as he did not recognise all the finches that existed.

 Darwin's finches
Darwin arrived at the Galapagos in the Beagle in 1835.
In his Journal of Researches (popularly known as The Voyage of the Beagle) Darwin famously commented that, 'in the thirteen species of ground-finches, a nearly perfect gradation may be traced from a beak extraordinarily thick to one so fine that it may be compared with that of a warbler.
Not only did the finches in question mate successfully, their offspring proved to be among the most fertile that the Grants recorded during their twenty years on the islands.

 Galapagos Direct Operator
Darwin's finches or Galapagos finches are species of small finches, constituting the subfamily Geospizinae of the finch family.
The Galapagos finches special adaptation to various habitats were important evidence considered by Charles Darwin in formulating the theory of evolution; they are a striking example of adaptive radiation.
Darwin proposed that the Galapagos finches evolved on the islands from a single species of finch from mainland South America.

 Who was Darwin?
In a scene eerily reminiscent of Darwin's grandmother's passing, his mother's last fortnight on earth was characterized by vomiting and severe gastro-intestinal pain while being tended to by her husband, Dr. Robert, as he administered vast quantities of the opium derivative laudanum to her.
Darwin related a strange story that was widely circulated around Shropshire of an incident that, though later denied by his father, and supposedly denied by the managing partner of the firm involved, at least according to Dr. Robert, was apparently corroborated by a great many eye witnesses:
Darwin, when on his death bed, abjectly whined for a minister and renouncing evolution, sought safety in the blood of the Saviour' is totally false and without any kind of foundation." Ibid, pp.117, The Darwin Legend, taken from The Huxley Papers, 8;135-137, 138-139.

 Darwin's Finches
All of Darwin's Finches are sparrow sized and similar in appearance with gray, brown, fl or olive feathers.
The Ground Finches eat ticks they remove with their crushing beaks from Tortoises, Land Iguanas and Marine Iguanas and kick eggs into rocks to feed upon their contents.
On Isla Wolf the Sharp Beaked Ground Finch is known as the "Vampire Finch" as it jumps on the backs of Masked Boobies and Red-Footed Boobies pecking at their flesh and feeding on their blood.

I have been reading about Kansas school board and their questioning about the treatment of Darwin, which has lead me to this post.
As a historic backdrop, Darwin presented his theory 10 yearsd prior to writting the decent of man, and thus had 10 years to really think about what his theory truely ment, and 10 years to make his points that man too is included in his theory.

 PATTERNS AND RATES OF SPECIES EVOLUTION
For example, Charles Darwin was able to establish that the various finches on the Galapagos islands were all related to each other, and had all presumably derived from a single ancestor on the nearest mainland, South America.
Darwin hoped for great improvements in knowledge of fossil lineages, especially through the Tertiary, so that all the discrete living species might be linked, through fossil forms, into their true phylogenetic patterns.
The example of Darwins finches, mentioned above, indicated that the present 14 species must have diverged from their common ancestor within the five million years of the existence of the Galapagos islands.

 Effects of the 1998 El Niño on Darwin’s finches on Daphne   (Site not responding. Last check: 2007-10-13)
In previous El Niño years, Darwin’s finches on two widely separated islands, Genovesa (Grant and Grant 1989) and Daphne Major (Gibbs and Grant 1987), responded in the same way to heavy rain and a prolonged wet season (Grant and Grant 1996).
For example, finch population densities were much higher at the beginning of 1998 than at the beginning of 1983, and finches probably interfered with each other’s attempt to breed at the beginning of 1998.
We thank Solanda Rea at the Charles Darwin Research Station for supplying temperature data, the numerous assistants who have given help in the field, L.F. Keller, K. Petren, E. Monson, and C. Edwards for help in the 1998 season, and G. Estes for reading the rain gauge when we were not on the island.

 Theory of Evolution - EvoWiki   (Site not responding. Last check: 2007-10-13)
The idea of evolution has been thought of by several people before Charles Darwin's time but Darwin came up with the theory of evolution by means of Natural Selection and gathered extensive material evidence to back up the theory.
In Darwin's time there was little understanding of heredity, but since then genetics has developed, and we have traced heredity to units of DNA, known as genes.
Charles Darwin studied allopatric speciation on the Galapagos islands, where populations of finches had become isolated by the water between the islands.

They say thing like "Darwins theory is one of the most proven theorys in all of science", never mind it doesn't enjoy kids in school turn one spieces into another via their little experements (or anyone else for that matter).
Far better simply to point out that Darwins work, like God work, is a matter that does not enjoy replicatable experement, and thus in either case, is not really all that strong in terms of being 'science' as such.

 Response from CDF to article on parasites in Darwins finches
A large majority of nests they studied exhibited the presence of the fly parasites, and 27% of nests exhibited brood loss due to the parasites, although only 19% exhibited complete brood loss (no chicks surviving to fledging) due to the parasites.
The level of threat to Darwin's finches and other native birds is difficult to assess, because the distribution, abundance, and effects are not understood.
The Charles Darwin Foundation has an active research program underway to monitor the distribution and potential effects of the parasitic flies on the avifauna of the islands.

 Free Term Papers on Darwins finches
Darwin is known for his studies of the thirteen species of finches that live on the Galapagos Islands.
The finches were extremely similar but had differences in beak shapes and sizes that he believed changed slowly over time to adapt to certain conditions.
The finches with smaller bodies and smaller beaks survived and reproduced because they were able to eat the seeds fast and more easily.

 Lecture 17 Community ecology (continued)
David Lack’s studies on Darwin’s finches revealed evidence of character displacement.
Found that on islands where they coexisted their range in bill sizes did not overlap (presumed to reflect differences in seeds taken to avoid overlap) but on islands where they did not overlap bill sizes were very similar – interpretation here is that competition leads to character displacement.
Long-term studies conducted by Dr. Peter Grant on the island of Daphne in Galapagos over the past 20+ years reveal potential for character displacement In Darwins finches.

Of course, you're going to explain that Social Darwinism arose before Darwinism (as "Social Statics," a term coined by Herbert Spencer, who changed the name of his pet concept after Darwinism took off.
On the contrary, if you're going to spend so much time on such a nitpicking (not to mention misleading) criticism of evolutionary theory, I'd think you should give creationism equal time.
If you fault the evolutionary explanation of the fossil record, let's take a look at the creationist explanation -- assuming there is one, and assuming it doesn't require oak trees to outrun velociraptors in the quest for the high ground during the Flood.
