The flowering plants known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families 13,164 known genera and c. 369,000 known species. Like gymnosperms, angiosperms are seed-producing plants. However, they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, the production of fruits that contain the seeds. Etymologically, angiosperm means a plant; the term comes from the Greek words sperma. The ancestors of flowering plants diverged from gymnosperms in the Triassic Period, 245 to 202 million years ago, the first flowering plants are known from 160 mya, they diversified extensively during the Early Cretaceous, became widespread by 120 mya, replaced conifers as the dominant trees from 100 to 60 mya. Angiosperms differ from other seed plants in several ways, described in the table below; these distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants and the most commercially important group to humans.
Angiosperm stems are made up of seven layers. The amount and complexity of tissue-formation in flowering plants exceeds that of gymnosperms; the vascular bundles of the stem are arranged such that the phloem form concentric rings. In the dicotyledons, the bundles in the young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium. By the formation of a layer of cambium between the bundles, a complete ring is formed, a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside; the soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Owing to differences in the character of the elements produced at the beginning and end of the season, the wood is marked out in transverse section into concentric rings, one for each season of growth, called annual rings.
Among the monocotyledons, the bundles are more numerous in the young stem and are scattered through the ground tissue. They once formed the stem increases in diameter only in exceptional cases; the characteristic feature of angiosperms is the flower. Flowers show remarkable variation in form and elaboration, provide the most trustworthy external characteristics for establishing relationships among angiosperm species; the function of the flower is to ensure fertilization of the ovule and development of fruit containing seeds. The floral apparatus may arise terminally from the axil of a leaf; as in violets, a flower arises singly in the axil of an ordinary foliage-leaf. More the flower-bearing portion of the plant is distinguished from the foliage-bearing or vegetative portion, forms a more or less elaborate branch-system called an inflorescence. There are two kinds of reproductive cells produced by flowers. Microspores, which will divide to become pollen grains, are the "male" cells and are borne in the stamens.
The "female" cells called megaspores, which will divide to become the egg cell, are contained in the ovule and enclosed in the carpel. The flower may consist only of these parts, as in willow, where each flower comprises only a few stamens or two carpels. Other structures are present and serve to protect the sporophylls and to form an envelope attractive to pollinators; the individual members of these surrounding structures are known as petals. The outer series is green and leaf-like, functions to protect the rest of the flower the bud; the inner series is, in general, white or brightly colored, is more delicate in structure. It functions to attract bird pollinators. Attraction is effected by color and nectar, which may be secreted in some part of the flower; the characteristics that attract pollinators account for the popularity of flowers and flowering plants among humans. While the majority of flowers are perfect or hermaphrodite, flowering plants have developed numerous morphological and physiological mechanisms to reduce or prevent self-fertilization.
Heteromorphic flowers have short carpels and long stamens, or vice versa, so animal pollinators cannot transfer pollen to the pistil. Homomorphic flowers may employ a biochemical mechanism called self-incompatibility to discriminate between self and non-self pollen grains. In other species, the male and female parts are morphologically separated, developing on different flowers; the botanical term "Angiosperm", from the Ancient Greek αγγείον, angeíon and σπέρμα, was coined in the form Angiospermae by Paul Hermann in 1690, as the name of one of his primary divisions of the plant kingdom. This included flowering plants possessing seeds enclosed in capsules, distinguished from his Gymnospermae, or flowering plants with achenial or schizo-carpic fruits, the whole fruit or each of its pieces being here regarded as a seed and naked; the term and its antonym were maintained by Carl Linnaeus with the same sense, but with restricted application, in the names of the orders of his class Didynamia. Its use with any
Queensland is the second-largest and third-most populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west and south respectively. To the east, Queensland is bordered by the Coral Pacific Ocean. To its north is the Torres Strait, with Papua New Guinea located less than 200 km across it from the mainland; the state is the world's sixth-largest sub-national entity, with an area of 1,852,642 square kilometres. As of 15 May 2018, Queensland has a population of 5,000,000, concentrated along the coast and in the state's South East; the capital and largest city in the state is Australia's third-largest city. Referred to as the "Sunshine State", Queensland is home to 10 of Australia's 30 largest cities and is the nation's third-largest economy. Tourism in the state, fuelled by its warm tropical climate, is a major industry. Queensland was first inhabited by Torres Strait Islanders.
The first European to land in Queensland was Dutch navigator Willem Janszoon in 1606, who explored the west coast of the Cape York Peninsula near present-day Weipa. In 1770, Lieutenant James Cook claimed the east coast of Australia for the Kingdom of Great Britain; the colony of New South Wales was founded in 1788 by Governor Arthur Phillip at Sydney. Queensland was explored in subsequent decades until the establishment of a penal colony at Brisbane in 1824 by John Oxley. Penal transportation ceased in 1839 and free settlement was allowed from 1842; the state was named in honour of Queen Victoria, who on 6 June 1859 signed Letters Patent separating the colony from New South Wales. Queensland Day is celebrated annually statewide on 6 June. Queensland was one of the six colonies which became the founding states of Australia with federation on 1 January 1901; the history of Queensland spans thousands of years, encompassing both a lengthy indigenous presence, as well as the eventful times of post-European settlement.
The north-eastern Australian region was explored by Dutch and French navigators before being encountered by Lieutenant James Cook in 1770. The state has witnessed frontier warfare between European settlers and Indigenous inhabitants, as well as the exploitation of cheap Kanaka labour sourced from the South Pacific through a form of forced recruitment known at the time as "blackbirding"; the Australian Labor Party has its origin as a formal organisation in Queensland and the town of Barcaldine is the symbolic birthplace of the party. June 2009 marked the 150th anniversary of its creation as a separate colony from New South Wales. A rare record of early settler life in north Queensland can be seen in a set of ten photographic glass plates taken in the 1860s by Richard Daintree, in the collection of the National Museum of Australia; the Aboriginal occupation of Queensland is thought to predate 50,000 BC via boat or land bridge across Torres Strait, became divided into over 90 different language groups.
During the last ice age Queensland's landscape became more arid and desolate, making food and other supplies scarce. This led to the world's first seed-grinding technology. Warming again made the land hospitable, which brought high rainfall along the eastern coast, stimulating the growth of the state's tropical rainforests. In February 1606, Dutch navigator Willem Janszoon landed near the site of what is now Weipa, on the western shore of Cape York; this was the first recorded landing of a European in Australia, it marked the first reported contact between European and Aboriginal Australian people. The region was explored by French and Spanish explorers prior to the arrival of Lieutenant James Cook in 1770. Cook claimed the east coast under instruction from King George III of the United Kingdom on 22 August 1770 at Possession Island, naming Eastern Australia, including Queensland,'New South Wales'; the Aboriginal population declined after a smallpox epidemic during the late 18th century. In 1823, John Oxley, a British explorer, sailed north from what is now Sydney to scout possible penal colony sites in Gladstone and Moreton Bay.
At Moreton Bay, he found the Brisbane River. He established a settlement at what is now Redcliffe; the settlement known as Edenglassie, was transferred to the current location of the Brisbane city centre. Edmund Lockyer discovered outcrops of coal along the banks of the upper Brisbane River in 1825. In 1839 transportation of convicts was ceased, culminating in the closure of the Brisbane penal settlement. In 1842 free settlement was permitted. In 1847, the Port of Maryborough was opened as a wool port; the first free immigrant ship to arrive in Moreton Bay was the Artemisia, in 1848. In 1857, Queensland's first lighthouse was built at Cape Moreton. A war, sometimes called a "war of extermination", erupted between Aborigines and settlers in colonial Queensland; the Frontier War was notable for being the most bloody in Australia due to Queensland's larger pre-contact indigenous population when compared to the other Australian colonies. About 1,500 European settlers and their alli
The Fabaceae or Leguminosae known as the legume, pea, or bean family, are a large and economically important family of flowering plants. It includes trees and perennial or annual herbaceous plants, which are recognized by their fruit and their compound, stipulate leaves. Many legumes have characteristic fruits; the family is distributed, is the third-largest land plant family in terms of number of species, behind only the Orchidaceae and Asteraceae, with about 751 genera and about 19,000 known species. The five largest of the genera are Astragalus, Indigofera and Mimosa, which constitute about a quarter of all legume species; the ca. 19,000 known legume species amount to about 7% of flowering plant species. Fabaceae is the most common family found in tropical rainforests and in dry forests in the Americas and Africa. Recent molecular and morphological evidence supports the fact that the Fabaceae is a single monophyletic family; this conclusion has been supported not only by the degree of interrelation shown by different groups within the family compared with that found among the Leguminosae and their closest relations, but by all the recent phylogenetic studies based on DNA sequences.
These studies confirm that the Fabaceae are a monophyletic group, related to the Polygalaceae and Quillajaceae families and that they belong to the order Fabales. Along with the cereals, some fruits and tropical roots, a number of Leguminosae have been a staple human food for millennia and their use is related to human evolution; the Fabaceae family includes a number of important agricultural and food plants, including Glycine max, Pisum sativum, Cicer arietinum, Medicago sativa, Arachis hypogaea, Ceratonia siliqua, Glycyrrhiza glabra. A number of species are weedy pests in different parts of the world, including: Cytisus scoparius, Robinia pseudoacacia, Ulex europaeus, Pueraria lobata, a number of Lupinus species; the name'Fabaceae' comes from the defunct genus Faba, now included in Vicia. The term "faba" comes from Latin, appears to mean "bean". Leguminosae is an older name still considered valid, refers to the fruit of these plants, which are called legumes. Fabaceae range in habit from giant trees to small annual herbs, with the majority being herbaceous perennials.
Plants have indeterminate inflorescences. The flowers have a short hypanthium and a single carpel with a short gynophore, after fertilization produce fruits that are legumes; the Leguminosae have a wide variety of growth forms, including trees, herbaceous plants, vines or lianas. The herbaceous plants can be annuals, biennials, or perennials, without basal or terminal leaf aggregations. Many Legumes have tendrils, they are epiphytes, or vines. The latter support themselves by means of shoots that twist around a support or through cauline or foliar tendrils. Plants can be mesophytes, or xerophytes; the leaves are alternate and compound. Most they are even- or odd-pinnately compound trifoliate and palmately compound, in the Mimosoideae and the Caesalpinioideae bipinnate, they always have stipules, which can be rather inconspicuous. Leaf margins are entire or serrate. Both the leaves and the leaflets have wrinkled pulvini to permit nastic movements. In some species, leaflets have evolved into tendrils.
Many species have leaves with structures that attract ants that protect the plant from herbivore insects. Extrafloral nectaries are common among the Mimosoideae and the Caesalpinioideae, are found in some Faboideae. In some Acacia, the modified hollow stipules are known as domatia. Many Fabaceae host bacteria in their roots within structures called root nodules; these bacteria, known as rhizobia, have the ability to take nitrogen gas out of the air and convert it to a form of nitrogen, usable to the host plant. This process is called nitrogen fixation; the legume, acting as a host, rhizobia, acting as a provider of usable nitrate, form a symbiotic relationship. The flowers have five fused sepals and five free petals, they are hermaphrodite, have a short hypanthium cup shaped. There are ten stamens and one elongated superior ovary, with a curved style, they are arranged in indeterminate inflorescences. Fabaceae are entomophilous plants, the flowers are showy to attract pollinators. In the Caesalpinioideae, the flowers are zygomorphic, as in Cercis, or nearly symmetrical with five equal petals in Bauhinia.
The upper petal is the innermost one, unlike in the Faboideae. Some species, like some in the genus Senna, have asymmetric flowers, with one of the lower petals larger than the opposing one, the style bent to one side; the calyx, corolla, or stamens can be showy in this group. In the Mimosoideae, the flowers are actinomorphic and arranged in globose inflorescences; the petals are small and the stamens, which can be more than just 10, have long, coloured filaments, which are the showiest part of the flower. All of the flowers in an inflorescence open at once. In the Faboideae, the flowers are zygom
Charleville is a town and a locality in the Shire of Murweh, Australia. In the 2016 census, Charleville had a population of 3,335 people. Located in south western Queensland, Charleville is 683 kilometres west of Brisbane, it is the largest town and administrative centre of the Shire of Murweh, which covers an area of 43,905 square kilometres. Charleville is situated on the banks of the Warrego River, is the terminus for the Warrego Highway; the first European exploration of the area, Kunja tribal land, was conducted by Edmund Kennedy in 1847. A hotel was built in 1865, a town began to grow to service the region, it was situated near Gowrie's Crossing, a permanent waterhole, now on the outskirts of the modern town. Gowrie Station had been established around the crossing along a natural stock route, for the grazing of sheep and cattle; the town was gazetted on 11 January 1865. It was planned with wide streets to enable bullock teams of up to 14 pairs to turn with their wagons, it was William Alcock Tully, Commissioner of Crown Lands in the Warrego District from 1863 to 1864, who laid out the town's streets.
An Irishman, Tully named the town after the town of Charleville, County Cork, Ireland. Members of the Roma-based Skinner family established a store in the town in 1872 that became known as the Warrego Stores. Charleville Post Office opened on 1 August 1865. In September 1875, the Queensland Government called for tenders to erect a courthouse in Charleville; the foundation stone was laid on 23 November 1875. By January 1876, the courthouse was finished. In December 1884, the Queensland Government called for tenders to erect a hospital in Charleville. In March 1885 the contract was awarded to King for £ 2,265 10s. In November 1885, a hospital ball was held in the new hospital building, suggesting it was completed and opened around that time. Cobb and Co, the legendary Australian stagecoach company, established a coach building business in the town in 1886, the railway arrived in 1888, beginning the long demise of coach transport in the area. Charleville station was the terminus for the Western railway line for more than a decade.
Facilities included a locomotive depot and sheep yards, a 50-ton weighbridge, a booking and telegraph offices, goods shed, stationmaster's house, guards and firemen's cottages. In 1902 Charleville was the location of an unsuccessful attempt by Clement Lindley Wragge to fire cannons into the clouds in order to break a drought; the cannons used remain on display in Charleville today. In 1922, Qantas established an airmail service between Cloncurry. At the same time, this was Qantas's first scheduled route and the second scheduled air route in Australia. On 9 October 1924, the Charleville War Memorial was unveiled by Sir Matthew Nathan, the Governor of Queensland. Charleville was one of the compulsory stop over/check points during the London to Melbourne MacRobertson Air Race in 1934; the winners of the great race were C. W. A. Scott, their triumph was reported in Time magazine as: "Scott and Black, keeping up their sensational pace, flashed into Charleville, sped toward the finish where waiting thousands cheered their progress, reported over loudspeakers.
With one motor dead, with only two hours sleep since leaving England, the Britons triumphantly set their scarlet torpedo down in Melbourne at 3:34 p.m. In 71 hr. 1 min. 3 sec. – Just under three days – they had flown halfway around the world." Proximity to the Warrego River has been problematic. In April 1990, major floods hit western Queensland, with Charleville being badly affected. Floodwaters peaked at 8.54 metres, over 1,000 homes were inundated, 3,000 people evacuated. More the district suffered flooding again in 1997, 2008 and March 2010. Flooding occurred in February 2012. There is a children's book called The Flood Grungies, it is about the notorious Charleville floods and features the Cosmos centre, the water tower and other famous landmarks. Charleville has a number of heritage-listed sites, including: 87 Alfred Street: former Queensland National Bank Edward Street: Charleville War Memorial King Street: Charleville railway station Mitchell Highway: Landsborough's Blazed Tree 33 Wills Street: Hotel Coronesas well as a number in nearby localities: 28 kilometres south-west of Charleville off the Diamantina Developmental Road in Bakers Bend: Myendetta Homestead 29 kilometres south of Charleville off the Mitchell Highway in Bakers Bend: Landsborough's Blazed Tree According to the 2016 census of Population, there were 3,335 people in Charleville.
Aboriginal and Torres Strait Islander people made up 15.3% of the population. 83.6% of people were born in Australia. The next most common country of birth was Vietnam at 3.3%. 87.6% of people spoke only English at home. Other languages spoken at home included Vietnamese at 3.5%. The most common responses for religion were Catholic 34.1%, Anglican 24.1% and No Religion 17.2%, Charleville has a humid subtropical climate verging on semi-arid, with maximum temperatures ranging from 35 °C in summer to 20 °C in winter. Summers are hot and sultry, although they can be dry as well depending on the wind direction. Winters crisp, with rather high diurnal ranges, which provide some frost. Rainfall is mild and distributed patchily with a peak in summer. Severe flooding events are caused by monsoon troughs and the remnants of tropical cyclones dumping large amounts of rain over the area.
Bush bread, or seedcakes, refers to the bread made by Australian Aboriginals for many thousands of years, by crushing seeds into a dough, after which it is baked. The bread was high in protein and carbohydrate, helped form part of a balanced traditional diet. With the arrival of Europeans and pre-milled white flour, this bread-making process all but disappeared; the tradition of cooking bread in hot coals continues today. Bread-making was a woman's task, it was carried out by several women at once, due to its labour-intensive nature. It involved collecting seasonal grains, roots or nuts, preparing these into flour and dough, or directly into a dough. Seeds varied depending on the area in Australia that the people lived. In Central Australia, native millet and spinifex were used. Wattleseed could be used in the flour mix. Women harvested the ripe, dry seeds of the plant by beating the grass with sticks to dislodge the seeds; some species were eaten at the green stage and, when ground, would produce a juice at the side of the millstone, drunk directly.
Some seeds need to be heated and ground dry, while others can be ground with water. In the Kimberley region of Western Australia, women observed that, after the dry season, many seeds would be gathered around the opening of harvester ants' nests; the ants had collected and husked the seed for them, they were able to collect this seed, making their job a lot easier. After allowing the grain to dry, they could begin to prepare the flour. Pigwig, Prickly wattle, Dead finish seed, Bush bean. After the grain was collected, it needed to be winnowed, done using the coolamon, the multi-purpose carrying vessel. Sometimes it needed to be winnowed several times. Once the grain was winnowed, it was ground using a millstone. Millstones have been discovered; the flour was mixed with water to make a dough and placed in hot ashes for baking. The results could be small buns, today referred to as johnny cakes, or a large loaf, known today as damper. Damper appears to be a mix of this traditional style of bread-making and European-style bread-making.
The dough could be eaten raw. Cooking was a good way to prepare the bread. Bread could be made from roots and corms of plants. In the Top End of Australia, people such as the Yolngu used wild taro; these were ground mixed to a paste to make bread. Water lily seed bread was popular in the Top End; the two species of water lily used were Nymphaea macrosperma. During the early part of the dry season, water lilies were an important part of the diet, with seed pods eaten raw or ground into paste. Women had expert knowledge of; the seeds of the cycad palm, Cycas media, are carcinogenic when raw, require elaborate treatment including shelling, leaching in running water for up to five days cooking. After this they are made into small loaves. In Queensland, the people of the Mount Tamborine area used the bunya pine cone, endemic to the area, to make bread in this way. Ill-fated explorers Burke and Wills survived on bush bread for some time after they ran out of rations due to the death of their camels; the Cooper Creek Aboriginals, the Yandruwandha people, gave them fish, beans called padlu, bread made from the ground sporocarps of the ngardu plant.
There is some evidence. Wills's last journal entry includes the following:..starvation on nardoo is by no means unpleasant, but for the weakness one feels, the utter inability to move oneself, for as far as appetite is concerned, it gives me the greatest satisfaction. Fat and sugar would be more to one's taste, in fact, those seem to me to be the great stand by for one in this extraordinary continent, it is possible that the explorers, in preparing the bread themselves, were not preparing it in the traditional way of the Aboriginal people, which may have involved soaking seeds prior to grinding in order to remove the enzyme thiaminase, which depletes the body of vitamin B1. It is therefore believed that the deaths of Burke and Wills resulted in part from the vitamin deficiency disease beri-beri. However, other research suggests that scurvy and environmental factors contributed to their deaths. Peterson, Donald Thomson in Arnhem Land, Melbourne University Press ISBN 0-522-85063-4, pp168–9.

Binomial nomenclature called binominal nomenclature or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomen, binominal name or a scientific name; the first part of the name – the generic name – identifies the genus to which the species belongs, while the second part – the specific name or specific epithet – identifies the species within the genus. For example, humans belong within this genus to the species Homo sapiens. Tyrannosaurus rex is the most known binomial; the formal introduction of this system of naming species is credited to Carl Linnaeus beginning with his work Species Plantarum in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book Pinax theatri botanici many names of genera that were adopted by Linnaeus; the application of binomial nomenclature is now governed by various internationally agreed codes of rules, of which the two most important are the International Code of Zoological Nomenclature for animals and the International Code of Nomenclature for algae and plants.
Although the general principles underlying binomial nomenclature are common to these two codes, there are some differences, both in the terminology they use and in their precise rules. In modern usage, the first letter of the first part of the name, the genus, is always capitalized in writing, while that of the second part is not when derived from a proper noun such as the name of a person or place. Both parts are italicized when a binomial name occurs in normal text, thus the binomial name of the annual phlox is now written as Phlox drummondii. In scientific works, the authority for a binomial name is given, at least when it is first mentioned, the date of publication may be specified. In zoology "Patella vulgata Linnaeus, 1758"; the name "Linnaeus" tells the reader who it was that first published a description and name for this species of limpet. "Passer domesticus". The original name given by Linnaeus was Fringilla domestica; the ICZN does not require that the name of the person who changed the genus be given, nor the date on which the change was made, although nomenclatorial catalogs include such information.
In botany "Amaranthus retroflexus L." – "L." is the standard abbreviation used in botany for "Linnaeus". "Hyacinthoides italica Rothm. – Linnaeus first named this bluebell species Scilla italica. The name is composed of two word-forming elements: "bi", a Latin prefix for two, "-nomial", relating to a term or terms; the word "binomium" was used in Medieval Latin to mean a two-term expression in mathematics. Prior to the adoption of the modern binomial system of naming species, a scientific name consisted of a generic name combined with a specific name, from one to several words long. Together they formed a system of polynomial nomenclature; these names had two separate functions. First, to designate or label the species, second, to be a diagnosis or description. In a simple genus, containing only two species, it was easy to tell them apart with a one-word genus and a one-word specific name; such "polynomial names" may sometimes look like binomials, but are different. For example, Gerard's herbal describes various kinds of spiderwort: "The first is called Phalangium ramosum, Branched Spiderwort.
The other... is aptly termed Phalangium Ephemerum Virginianum, Soon-Fading Spiderwort of Virginia". The Latin phrases are short descriptions, rather than identifying labels; the Bauhins, in particular Caspar Bauhin, took some important steps towards the binomial system, by pruning the Latin descriptions, in many cases to two words. The adoption by biologists of a system of binomial nomenclature is due to Swedish botanist and physician Carl von Linné, more known by his Latinized name Carl Linnaeus, it was in his 1753 Species Plantarum that he first began using a one-word "trivial name" together with a generic name in a system of binomial nomenclature. This trivial name is what is now known as specific name; the Bauhins' genus names were retained in many of these, but the descriptive part was reduced to a single word. Linnaeus's trivial names introduced an important new idea, namely that the function of a name could be to give a species a unique label; this meant. Thus Gerard's Phalangium ephemerum virginianum became Tradescantia virgi
Indigenous Australians are the Aboriginal and Torres Strait Islander peoples of Australia, descended from groups that existed in Australia and surrounding islands before British colonisation. The time of arrival of the first Indigenous Australians is a matter of debate among researchers; the earliest conclusively human remains found in Australia are those of Mungo Man LM3 and Mungo Lady, which have been dated to around 50,000 years BP. Recent archaeological evidence from the analysis of charcoal and artefacts revealing human use suggests a date as early as 65,000 BP. Luminescence dating has suggested habitation in Arnhem Land as far back as 60,000 years BP. Genetic research has inferred a date of habitation as early as 80,000 years BP. Other estimates have ranged up to 100,000 years and 125,000 years BP. Although there are a number of commonalities between Indigenous Aboriginal Australians, there is a great diversity among different Indigenous communities and societies in Australia, each with its own mixture of cultures and languages.
In present-day Australia these groups are further divided into local communities. At the time of initial European settlement, over 250 languages were spoken. Aboriginal people today speak English, with Aboriginal phrases and words being added to create Australian Aboriginal English; the population of Indigenous Australians at the time of permanent European settlement is contentious and has been estimated at between 318,000 and 1,000,000 with the distribution being similar to that of the current Australian population, the majority living in the south-east, centred along the Murray River. A population collapse principally from disease followed European settlement beginning with a smallpox epidemic spreading three years after the arrival of Europeans. Massacres and war by British settlers contributed to depopulation; the characterisation of this violence as genocide is controversial and disputed. Since 1995, the Australian Aboriginal Flag and the Torres Strait Islander Flag have been among the official flags of Australia.
The word aboriginal has been in the English language since at least the 16th century to mean, "first or earliest known, indigenous". It comes from the Latin word aborigines, derived from origo; the word was used in Australia to describe its indigenous peoples as early as 1789. It soon became employed as the common name to refer to all Indigenous Australians. While the term Indigenous Australians, has grown since the 1980s to be more inclusive of Torres Strait Islander people, many Aboriginal and Torres Strait Islander peoples dislike it, feeling that it is too generic and removes their identity. Being more specific, for example naming the language group, is considered best practice and most respectful. Terms that are considered disrespectful include Aborigine and ATSI The broad term Aboriginal Australians includes many regional groups that identify under names from local Indigenous languages; these include: Murrawarri people -- see Murawari language. Anindilyakwa on Groote Eylandt off Arnhem Land.
These larger groups may be further subdivided. It is estimated that before the arrival of British settlers, the population of Indigenous Australians was 318,000–750,000 across the continent; the Torres Strait Islanders possess a heritage and cultural history distinct from Aboriginal traditions. The eastern Torres Strait Islanders in particular are related to the Papuan peoples of New Guinea, speak a Papuan language. Accordingly, they are not included under the designation "Aboriginal Australians"; this has been another factor in the promotion of the more inclusive term "Indigenous Australians". Six percent of Indigenous Australians identify themselves as Torres Strait Islanders. A further 4% of Indigenous Australians identify themselves as having both Torres Strait Islander and Aboriginal heritage; the Torres Strait Islands comprise over 100 islands which were annexed by Queensland in 1879. Many Indigenous organisations incorporate the phrase "Aboriginal and Torres Strait Islander" to highlight the distinctiveness and importance of Torres Strait Islanders in Australia's Indigenous population.
Eddie Mabo was from "Mer" or Murray Island in the Torres Strait, which the famous Mabo decision of 1992 involved. The term "black" has been used to refer to Indigenous Australians since European settlement. While related to skin colour, the term is used today to indicate Aboriginal he
