Consumed Scrubfowl
The consumed scrubfowl (''Megapodius alimentum'') is an extinct megapode that was native to Fiji and Tonga in the south-west Pacific Ocean. It was originally described from subfossil remains collected by David Steadman from an archaeological site at Tongoleleka, on the island of Lifuka in the Haʻapai group of the Kingdom of Tonga. The specific epithet and vernacular name refer to its evident use as a food item. Subsequently, remains were also found on Lakeba and Mago in the Lau group of Fiji by Trevor Worthy. It likely became extinct through overhunting following human settlement of the islands some 3,500 years ago but may have persisted until the mid-late 19th century: A single megapode egg, olive-tan with slightly darker mottling, was collected in the mid-19th century on an undetermined island of the Haʻapai group by Lieutenant Burnaby of the Royal Navy – most likely on Lifuka, as this was and still is the commercial and political centre of the group. In 1861 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Winchester (1822)
HMS ''Winchester'' was a 60-gun sailing frigate of the Royal Navy. She was laid down in 1816 at Woolwich Dockyard, and launched on 21 June 1822. Although designed for 60 guns, she and the rest of the class carried 52 guns. From 1831 to 1861 she served in North America and Southeast Asia. In 1861 she became the training ship ''Conway'' at Liverpool, and from 1876 she was the training ship ''Mount Edgcumbe''. She was sold in 1921. Operational service Flagship in North America, Cape of Good Hope and the East Indies Although ordered in 1816 and laid down in 1818, ''Winchester'' was not launched until 21 June 1822, and commissioned on 16 September later that year. In October 1829 Captain Charles Austen, brother of the novelist Jane Austen, took command in Bermuda where ''Winchester'' was the flagship on the North America and West Indies Station. In 1832 Lord Willeam Paget commanded her until June 1833 when she was paid off. Between 1834 and 1838 she was on the East Indies ...

Birds Of Fiji
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Megapodius
The scrubfowl are the genus '' Megapodius '' of the mound-builders, stocky, medium-large chicken-like birds with small heads and large feet in the family Megapodiidae. They are found from south-east Asia to north Australia and islands in the west Pacific. They do not incubate their eggs with their body heat in the orthodox way, but bury them. They are best known for building a massive mound of decaying vegetation, which the male attends, adding or removing litter to regulate the internal heat while the eggs hatch. The species in taxonomic order are: * †Pile-builder scrubfowl (''Megapodius molistructor'') * †Viti Levu scrubfowl (''Megapodius amissus'') In all of the above, the name "scrubfowl" is sometimes exchanged with "megapode". Traditionally, most have been listed as subspecies of ''M. freycinet'', but today all major authorities consider this incorrect. Nevertheless, there are unresolved issues within the genus, and for example the taxon ''forstenii'' has been consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient DNA
Ancient DNA (aDNA) is DNA isolated from ancient specimens. Due to degradation processes (including cross-linking, deamination and fragmentation) ancient DNA is more degraded in comparison with contemporary genetic material. Even under the best preservation conditions, there is an upper boundary of 0.4–1.5 million years for a sample to contain sufficient DNA for sequencing technologies. The oldest sample ever sequenced is estimated to be 1.65 million years old. Genetic material has been recovered from paleo/archaeological and historical skeletal material, mummified tissues, archival collections of non-frozen medical specimens, preserved plant remains, ice and from permafrost cores, marine and lake sediments and excavation dirt. On 7 December 2022, ''The New York Times'' reported that two-million year old genetic material was found in Greenland, and is currently considered the oldest DNA discovered so far. History of ancient DNA studies 1980s The first study of what would ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megapodius Molistructor
The pile-builder megapode (''Megapodius molistructor'') is an extinct species of megapode. The subfossil remains were found by Jean-Christophe Balouet and Storrs L. Olson in the Pindai Caves of New Caledonia. Its remains have also been found on Tonga. Description With a weight of 3.5 kg, ''M. molistructor'' was heavier than all existing ''Megapodius'' species. On Tonga, it was the largest ground-dwelling bird species. The fossil material consists of a left tarsometatarsus, a complete left scapula, a half right scapula, a proximal-end left ulna, a fragment of the right femur, several ungual phalanges, an anterior-end right scapula, a proximal-end right ulna, a distal left ulna, a distal-end left ulna proximal, and a half right femur. Extinction When the early settlers of the Lapita culture arrived in Tonga around 1500 BC, they found only marine species such as sea turtles and giant forms of terrestrial birds such as megapodes, doves, and rails. The hunting of these bird s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megapodius Pritchardii
The Tongan megapode (''Megapodius pritchardii'') is a species of bird in the megapode family, Megapodiidae, currently endemic to Tonga. The species is also known as the Polynesian megapode, and as the Niuafo'ou megapode after the island of Niuafo'ou to which it was restricted for many years. The specific epithet honours British consul William Thomas Pritchard. Distribution and habitat The Tongan megapode is the only remaining species of megapode in Tonga out of the four or five species that were present on the islands in prehuman times (as shown through the fossil record), and indeed the only species of megapode that survives in Polynesia.Steadman D, (2006).

Megapodius Freycinet
The dusky megapode (''Megapodius freycinet''), also known as dusky scrubfowl or common megapode, is a medium-sized, approximately 41 cm (16 in) long, blackish bird with a short pointed crest, bare red facial skin, dark legs, brown irises, and a dark brown and yellow bill. The male and female are similar. This terrestrial species lives in forests and swamps, including mangroves, of the Maluku and Raja Ampat Islands in Indonesia. Like other megapodes, it lays its eggs in a mound made from earth mixed with leaves, sand, gravel, and sticks, which can be as large as in diameter and stand nearly tall. Many authorities include the Biak scrubfowl as a subspecies of this species, but the two are increasingly treated as separate species. At the same time, many authorities consider the taxon ''M. forstenii'' a separate species, Forsten's megapode, but measurements and molecular evidence suggest the two are very close,Birks, S. M., & Edwards, S. V. (2002). ''A phylogeny of the me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Robert Gray
George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years. He was the younger brother of the zoologist John Edward Gray and the son of the botanist Samuel Frederick Gray. George Gray's most important publication was his ''Genera of Birds'' (1844–49), illustrated by David William Mitchell and Joseph Wolf, which included 46,000 references. Biography He was born in Little Chelsea, London, to Samuel Frederick Gray, naturalist and pharmacologist, and Elizabeth (née Forfeit), his wife. He was educated at Merchant Taylor's School. Gray started at the British Museum as Assistant Keeper of the Zoology Branch in 1831. He began by cataloguing insects, and published an ''Entomology of Australia'' (1833) and contributed the entomogical section to an English edition of Georges Cuvier's ''Animal Kingdom''.

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domina ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
