1602-506: A distinguishing element of Canada's political culture. Peace, order, and good government , alongside an Implied Bill of Rights , are founding principles of Canadian federalism . At the federal level, Canada has been dominated by two relatively centrist parties practising "brokerage politics": the centre-left leaning Liberal Party of Canada and the centre-right leaning Conservative Party of Canada (or its predecessors ). The historically predominant Liberals position themselves at

1780-516: A formally independent federation on 1 October 1960. It experienced a civil war from 1967 to 1970, followed by a succession of military dictatorships and democratically elected civilian governments until achieving a stable government in the 1999 Nigerian presidential election , with the election of Olusegun Obasanjo of the Peoples Democratic Party .

As a result, by August 2006, the database included more than ten million SNPs, and more than 40% of them were known to be polymorphic . By comparison, at the start of the project, fewer than 3 million SNPs were identified, and no more than 10% of them were known to be polymorphic. During Phase II, more than two million additional SNPs were genotyped throughout

2314-432: A river system. The river system of the northeast is also a major river system. In addition, Nigeria has numerous coastal rivers. Over the last million years, Lake Chad in the far north-east of Nigeria has dried up several times for a few thousand years and just as often growing to many times its current size. In recent decades its surface area has been reduced considerably, which may also be due to humans taking water from

2492-455: A shortcut. Although any two unrelated people share about 99.5% of their DNA sequence, their genomes differ at specific nucleotide locations. Such sites are known as single nucleotide polymorphisms (SNPs), and each of the possible resulting gene forms is called an allele . The HapMap project focuses only on common SNPs, those where each allele occurs in at least 1% of the population. Each person has two copies of all chromosomes , except

Nigeria's constitution ensures de jure freedom of religion , and it is home to some of the world's largest Muslim and Christian populations. Nigeria is divided roughly in half between Muslims , who live mostly in the north part of the country, and Christians , who live mostly in the south; indigenous religions , such as those native to

3738-524: Is a better model of UK British individuals than is CEU alone. It was expensive in the 1990s to sequence patients’ whole genomes. So the National Institutes of Health embraced the idea for a "shortcut", which was to look just at sites on the genome where many people have a variant DNA unit. The theory behind the shortcut was that, since the major diseases are common, so too would be the genetic variants that caused them. Natural selection keeps

13528-600: The Niger and the Cross Rivers has lost most of its forest because of development and harvesting by increased population and has been replaced by grassland . Everything in between the far south and the far north is savannah (insignificant tree cover, with grasses and flowers located between trees). Rainfall is more limited to between 500 and 1,500 millimetres (20 and 60 in) per year. The savannah zone's three categories are Guinean forest-savanna mosaic , Sudan savannah, and Sahel savannah. Guinean forest-savanna mosaic

13706-587: The Nigerian government, with Nigeria utilizing air support from Egyptian pilots provided by Gamal Abdel Nasser , while France and Israel aided the Biafrans. The Congolese government, under President Joseph-Désiré Mobutu , took an early stand on the Biafran secession, voicing strong support for the Nigerian federal government and deploying thousands of troops to fight against the secessionists . Following

13884-540: The Norse built a small short-lived encampment that was occupied sporadically for perhaps 20 years at L'Anse aux Meadows on the northern tip of Newfoundland . No further European exploration occurred until 1497, when seafarer John Cabot explored and claimed Canada's Atlantic coast in the name of Henry VII of England . In 1534, French explorer Jacques Cartier explored the Gulf of Saint Lawrence where, on July 24, he planted

14062-735: The Northwest Territories, Parliament created the Yukon Territory. Alberta and Saskatchewan became provinces in 1905. Between 1871 and 1896, almost one quarter of the Canadian population emigrated south to the US. To open the West and encourage European immigration, the Government of Canada sponsored the construction of three transcontinental railways (including the Canadian Pacific Railway ), passed

14240-708: The Parliament of Canada. Nigeria Nigeria , officially the Federal Republic of Nigeria , is a country in West Africa . It is situated between the Sahel to the north and the Gulf of Guinea to the south in the Atlantic Ocean . It covers an area of 923,769 square kilometres (356,669 sq mi). With a population of more than 230 million, it is the most populous country in Africa , and

14418-593: The Saint Lawrence River. Following the British conquest of New France , this area was known as the British Province of Quebec from 1763 to 1791. In 1791, the area became two British colonies called Upper Canada and Lower Canada . These two colonies were collectively named the Canadas until their union as the British Province of Canada in 1841. Upon Confederation in 1867 , Canada

14596-739: The Sharie catchment area. In the Sahel region, rain is less than 500 millimetres (20 in) per year, and the Sahara Desert is encroaching. In the dry northeast corner of the country lies Lake Chad , on a shared water boundary delimitation with Niger, Chad and Cameroon. The Chad Basin is fed from the north-eastern quarter of Nigeria. The Bauchi Plateau forms the watershed between the Niger/Benue and Komadugu Yobe river systems. The flat plains of north-eastern Nigeria are geographically part of

14774-709: The United Kingdom. The delay underscored Canada's independence. The first Canadian Army units arrived in Britain in December 1939. In all, over a million Canadians served in the armed forces during the Second World War . Canadian troops played important roles in many key battles of the war, including the failed 1942 Dieppe Raid , the Allied invasion of Italy , the Normandy landings , the Battle of Normandy , and

14952-601: The United States is the world's longest international land border. The country is characterized by a wide range of both meteorologic and geological regions. With a population of just over 41   million people, it has widely varying population densities, with the majority residing in urban areas and large areas of the country being sparsely populated. Canada's capital is Ottawa and its three largest metropolitan areas are Toronto , Montreal , and Vancouver . Indigenous peoples have continuously inhabited what

15130-642: The United States in 1846 ended the Oregon boundary dispute , extending the border westward along the 49th parallel . This paved the way for British colonies on Vancouver Island (1849) and in British Columbia (1858) . The Anglo-Russian Treaty of Saint Petersburg (1825) established the border along the Pacific coast, but, even after the US Alaska Purchase of 1867, disputes continued about

15308-473: The abortive Rebellions of 1837 . The Durham Report subsequently recommended responsible government and the assimilation of French Canadians into English culture. The Act of Union 1840 merged the Canadas into a united Province of Canada and responsible government was established for all provinces of British North America east of Lake Superior by 1855. The signing of the Oregon Treaty by Britain and

15486-484: The allele of one SNP for a given individual is known, the alleles of nearby SNPs can often be predicted, a process known as genotype imputation . This is because each SNP arose in evolutionary history as a single point mutation , and was then passed down on the chromosome surrounded by other, earlier, point mutations. SNPs that are separated by a large distance on the chromosome are typically not very well correlated, because recombination occurs in each generation and mixes

15664-507: The allele sequences of the two chromosomes. A sequence of consecutive alleles on a particular chromosome is known as a haplotype . To find the genetic factors involved in a particular disease, one can proceed as follows. First a certain region of interest in the genome is identified, possibly from earlier inheritance studies. In this region one locates a set of tag SNPs from the HapMap data; these are SNPs that are very well correlated with all

15842-552: The border with Cameroon , where the montane land is part of the Bamenda Highlands of Cameroon. The far south is defined by its tropical rainforest climate , where annual rainfall is 1,500 to 2,000 millimetres (60 to 80 in) per year. In the southeast stands the Obudu Plateau . Coastal plains are found in both the southwest and the southeast. Mangrove swamps are found along the coast. The area near

16020-593: The border with Cameroon close to the coast is rich rainforest and part of the Cross-Sanaga-Bioko coastal forests ecoregion , an important centre for biodiversity . It is a habitat for the drill primate , which is found in the wild only in this area and across the border in Cameroon. The areas surrounding Calabar , Cross River State, also in this forest, are believed to contain the world's largest diversity of butterflies. The area of southern Nigeria between

16198-405: The caliphate and the central Sokoto administration to prevent any defence as he worked towards the capital. As the British approached the city of Sokoto , Sultan Muhammadu Attahiru I organized a quick defence of the city and fought the advancing British-led forces. The British force quickly won, sending Attahiru I and thousands of followers on a Mahdist hijra . In the northeast, the decline of

16376-477: The canals, sewerage systems that are channels for water flows, and the like. Haphazard industrial planning, increased urbanisation, poverty and lack of competence of the municipal government are seen as the major reasons for high levels of waste pollution in major cities of the country. Some of the solutions have been disastrous to the environment, resulting in untreated waste being dumped in places where it can pollute waterways and groundwater . In 2005, Nigeria had

16554-743: The centre of the political scale. Five parties had representatives elected to the Parliament in the 2021 election —the Liberals, who formed a minority government; the Conservatives, who became the Official Opposition ; the New Democratic Party (occupying the left ); the Bloc Québécois ; and the Green Party . Far-right and far-left politics have never been a prominent force in Canadian society. Canada has

16732-565: The civil service. Colonel Buka Suka Dimka launched a February 1976 coup attempt , during which General Murtala Muhammed was assassinated. Dimka lacked widespread support among the military, and his coup failed, forcing him to flee. After the coup attempt, General Olusegun Obasanjo was appointed military head of state. Obasanjo vowed to continue Murtala's policies. Aware of the danger of alienating northern Nigerians, Obasanjo brought General Shehu Yar'Adua as his replacement and second-in-command as Chief of Staff, Supreme Headquarters completing

16910-695: The complete data obtained in Phase I were published on 27 October 2005. The analysis of the Phase II dataset was published in October 2007. The Phase III dataset was released in spring 2009 and the publication presenting the final results published in September 2010. Unlike with the rarer Mendelian diseases, combinations of different genes and the environment play a role in the development and progression of common diseases (such as diabetes , cancer , heart disease , stroke , depression , and asthma ), or in

17088-555: The constitution. The Supreme Court of Canada is the highest court, final arbiter, and has been led since 2017 by Richard Wagner , the Chief Justice of Canada . The governor general appoints the court's nine members on the advice of the prime minister and minister of justice . The federal Cabinet also appoints justices to superior courts in the provincial and territorial jurisdictions. Common law prevails everywhere except Quebec, where civil law predominates. Criminal law

17266-516: The continent during the North American fur trade . These early European interactions with First Nations would change from friendship and peace treaties to the dispossession of Indigenous lands through treaties . From the late 18th century, European Canadians forced Indigenous peoples to assimilate into a western Canadian society. Settler colonialism reached a climax in the late 19th and early 20th centuries. A period of redress began with

17444-576: The country and consists of written text and unwritten conventions. The Constitution Act, 1867 (known as the British North America Act, 1867 prior to 1982), affirmed governance based on parliamentary precedent and divided powers between the federal and provincial governments. The Statute of Westminster, 1931 , granted full autonomy, and the Constitution Act, 1982 , ended all legislative ties to Britain, as well as adding

17622-421: The country, particularly in the interior and Prairie provinces, which experience a continental climate , where daily average temperatures are near −15  °C (5  °F ), but can drop below −40 °C (−40 °F) with severe wind chills . In non-coastal regions, snow can cover the ground for almost six months of the year, while in parts of the north snow can persist year-round. Coastal British Columbia has

17800-490: The cultural and political differences were sharp among Nigeria's dominant ethnic groups: the Hausa in the north, Igbo in the east and Yoruba in the west. The Westminster system of government was retained, and thus the President 's powers were generally ceremonial. The parliamentary system of government had Abubakar Tafawa Balewa as Prime Minister and Nnamdi Azikiwe as the ceremonial president. The founding government

17978-570: The dictator died in the villa. He looted money to offshore accounts in Western European banks and defeated coup plots by arresting and bribing generals and politicians. His successor, General Abdulsalami Abubakar , adopted a new constitution on 5 May 1999, which provided for multiparty elections. On 29 May 1999, Abubakar handed over power to the winner of the 1999 presidential election, former military ruler General Olusegun Obasanjo , as President of Nigeria. Obasanjo had been in prison under

18156-516: The dictatorship of Abacha. Obasanjo's inauguration heralded the beginning of the Fourth Nigerian Republic, ending a 39-year period of short-lived democracies, civil war and military dictatorship. Although the elections that brought Obasanjo to power and allowed him to run for a second term in the 2003 presidential elections were condemned as unfree and unfair, Nigeria made significant progress in democratization under Obasanjo. In

18334-622: The direct control of the British government and established the Southern Nigeria Protectorate as a British protectorate and part of the British Empire . By 1902, the British had begun plans to move north into the Sokoto Caliphate. British General Lord Frederick Lugard was tasked by the Colonial Office to implement the agenda. Lugard used rivalries between many of the emirs in the southern reach of

18512-561: The duo of Moshood Abiola and Baba Gana Kingibe of the Social Democratic Party defeated Bashir Tofa and Sylvester Ugoh of the National Republican Convention by over 2.3 million votes. However, Babangida annulled the elections, leading to massive civilian protests that effectively shut down the country for weeks. In August 1993, Babangida finally kept his promise to relinquish power to

18690-723: The earliest known sculptures in sub-Saharan Africa and smelted iron by about 550 BC and possibly a few centuries earlier. Evidence of iron smelting has also been excavated at sites in the Nsukka region of southeast Nigeria: dating to 2000 BC at the site of Lejja and to 750 BC and at the site of Opi . The Kano Chronicle highlights an ancient history dating to around 999 AD of the Hausa Sahelian city-state of Kano , with other major Hausa cities (or Hausa Bakwai ) of Daura , Hadeija , Kano , Katsina , Zazzau , Rano , and Gobir all having recorded histories dating back to

18868-597: The early 1930s saw an economic downturn, leading to hardship across the country. In response to the downturn, the Co-operative Commonwealth Federation (CCF) in Saskatchewan introduced many elements of a welfare state (as pioneered by Tommy Douglas ) in the 1940s and 1950s. On the advice of Prime Minister William Lyon Mackenzie King , war with Germany was declared effective September 10, 1939, by King George VI , seven days after

19046-633: The emergence of a new Canadian identity , marked by the adoption of the maple leaf flag in 1965, the implementation of official bilingualism (English and French) in 1969, and the institution of official multiculturalism in 1971. Socially democratic programs were also instituted, such as Medicare , the Canada Pension Plan , and Canada Student Loans ; though, provincial governments, particularly Quebec and Alberta, opposed many of these as incursions into their jurisdictions. Finally, another series of constitutional conferences resulted in

19224-792: The emergence of a wave of terror by the Boko Haram insurgency , such as the Gwoza massacre and Chibok schoolgirls kidnapping in 2014. Ahead of the general election of 2015 , a merger of the biggest opposition parties in Nigeria – the Action Congress of Nigeria , the Congress for Progressive Change , the All Nigeria Peoples Party , a faction of the All Progressives Grand Alliance and

19402-693: The exact demarcation of the Alaska–Yukon and Alaska–BC border. Following three constitutional conferences, the British North America Act, 1867 officially proclaimed Canadian Confederation on July 1, 1867, initially with four provinces: Ontario , Quebec, Nova Scotia, and New Brunswick. Canada assumed control of Rupert's Land and the North-Western Territory to form the Northwest Territories , where

19580-416: The federal government and the 10 provinces. Provincial legislatures are unicameral and operate in parliamentary fashion similar to the House of Commons. Canada's three territories also have legislatures, but these are not sovereign, have fewer constitutional responsibilities than the provinces, and differ structurally from their provincial counterparts. The Constitution of Canada is the supreme law of

19758-488: The federal jurisdiction. It is very highly ranked in international measurements of government transparency, quality of life, economic competitiveness, innovation, education and human rights. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration . Canada's long and complex relationship with the United States has had a significant impact on its history , economy , and culture . A developed country , Canada has

19936-546: The first permanent year-round European settlements at Port Royal (in 1605) and Quebec City (in 1608). Among the colonists of New France, Canadiens extensively settled the Saint Lawrence River valley and Acadians settled the present-day Maritimes , while fur traders and Catholic missionaries explored the Great Lakes , Hudson Bay , and the Mississippi watershed to Louisiana . The Beaver Wars broke out in

20114-522: The first time since the return of democracy, no former military ruler ran for president, marking a strengthening of democracy and faith in the multiparty constitution . The election also saw the rise of metonymic supporters of the new candidates, the Obidient movement of Peter Obi , previously governor of Anambra State, widely appealed to young, urban voters and has his core base in the Southeast; and

20292-416: The forest zone's most southerly portion, especially around the Niger River and Cross River deltas, is mangrove swamp . North of this is a freshwater swamp, containing different vegetation from the saltwater mangrove swamps, and north of that is a rainforest. The savannah zone's three categories are divided into Guinean forest-savanna mosaic , made up of plains of tall grass which are interrupted by trees,

20470-499: The formation of a reconciliation commission by the Government of Canada in 2008. This included acknowledgment of cultural genocide , settlement agreements , and betterment of racial discrimination issues, such as addressing the plight of missing and murdered Indigenous women . It is believed that the first documented European to explore the east coast of Canada was Norse explorer Leif Erikson . In approximately 1000 AD,

20648-541: The fur trade, conflicts with the colonial authorities and settlers, and the loss of Indigenous lands to settlers and the subsequent collapse of several nations' self-sufficiency. Although not without conflict, European Canadians ' early interactions with First Nations and Inuit populations were relatively peaceful. First Nations and Métis peoples played a critical part in the development of European colonies in Canada , particularly for their role in assisting European coureurs des bois and voyageurs in their explorations of

20826-485: The genome by David R. Cox, Kelly A. Frazer and others at Perlegen Sciences and 500,000 by the company Affymetrix . All of the data generated by the project, including SNP frequencies, genotypes and haplotypes , were placed in the public domain and are available for download. This website also contains a genome browser which allows to find SNPs in any region of interest, their allele frequencies and their association to nearby SNPs. A tool that can determine tag SNPs for

21004-609: The growth of an independence movement in contrast to the Thirteen Colonies. The Proclamation and the Quebec Act in turn angered many residents of the Thirteen Colonies, further fuelling anti-British sentiment in the years prior to the American Revolution . After the successful American War of Independence, the 1783 Treaty of Paris recognized the independence of the newly formed United States and set

21182-591: The highest rate of deforestation in the world, according to the Food and Agriculture Organization of the United Nations . That year, 12.2%, the equivalent of 11,089,000 hectares, had been forested in the country. Between 1990 and 2000, Nigeria lost an average of 409,700 hectares of forest every year equal to an average annual deforestation rate of 2.4%. Between 1990 and 2005, in total Nigeria lost 35.7% of its forest cover or around 6,145,000 hectares. Nigeria had

21360-602: The human genome free of variants that damage health before children are grown, the theory held, but fails against variants that strike later in life, allowing them to become quite common (In 2002 the National Institutes of Health started a $ 138 million project called the HapMap to catalog the common variants in European, East Asian and African genomes). For the Phase I, one common SNP was genotyped every 5,000 bases. Overall, more than one million SNPs were genotyped. The genotyping

21538-456: The individual response to pharmacological agents. To find the genetic factors involved in these diseases, one could in principle do a genome-wide association study : obtain the complete genetic sequence of several individuals, some with the disease and some without, and then search for differences between the two sets of genomes. At the time, this approach was not feasible because of the cost of full genome sequencing . The HapMap project proposed

21716-407: The inlets to irrigate agricultural land. Nigeria is covered by three types of vegetation: forests (where there is significant tree cover), savannahs (insignificant tree cover, with grasses and flowers located between trees), and montane land (least common and mainly found in the mountains near the Cameroon border). Both the forest zone and the savannah zone are divided into three parts. Some of

21894-521: The introduction of European cattle farms and wheat fields dominating the land. The Indigenous peoples saw widespread famine and disease due to the loss of the bison and their traditional hunting lands. The federal government did provide emergency relief, on condition of the Indigenous peoples moving to the reserves. During this time, Canada introduced the Indian Act extending its control over

22072-415: The leadership of Sir George Taubman Goldie . By the late 19th and early 20th centuries, the company had vastly succeeded in subjugating the independent southern kingdoms along the Niger River , the British conquered Benin in 1897, and, in the Anglo-Aro War (1901–1902), defeated other opponents. The defeat of these states opened up the Niger area to British rule. In 1900, the company's territory came under

22250-410: The location of a large area of Central African mangroves . Nigeria's most expansive topographical region is that of the valleys of the Niger and Benue river valleys (which merge and form a Y-shape). To the southwest of the Niger is a "rugged" highland . To the southeast of the Benue are hills and mountains, which form the Mambilla Plateau , the highest plateau in Nigeria. This plateau extends through

22428-539: The main front in the War of 1812 between the United States and the United Kingdom . Peace came in 1815; no boundaries were changed. Immigration resumed at a higher level, with over 960,000 arrivals from Britain between 1815 and 1850. New arrivals included refugees escaping the Great Irish Famine as well as Gaelic -speaking Scots displaced by the Highland Clearances . Infectious diseases killed between 25 and 33 percent of Europeans who immigrated to Canada before 1891. The desire for responsible government resulted in

22606-454: The major coastal ports. Some of the more prolific slave-trading kingdoms who participated in the Atlantic slave trade were linked with the Edo's Benin Empire in the south, Oyo Empire in the southwest, and the Aro Confederacy in the southeast. Benin's power lasted between the 15th and 19th centuries. Oyo, at its territorial zenith in the late 17th to early 18th centuries, extended its influence from western Nigeria to modern-day Togo . In

22784-436: The mid-17th century over control of the North American fur trade. The English established additional settlements in Newfoundland in 1610 along with settlements in the Thirteen Colonies to the south. A series of four wars erupted in colonial North America between 1689 and 1763; the later wars of the period constituted the North American theatre of the Seven Years' War . Mainland Nova Scotia came under British rule with

22962-406: The middle reaches of the river around Timbuktu before 19th-century European colonialism . Before Flora Shaw suggested the name Nigeria , other proposed names included Royal Niger Company Territories , Central Sudan , Niger Empire , Niger Sudan , and Hausa Territories . Kainji Dam excavations showed ironworking by the 2nd century BC. The transition from Neolithic times to the Iron Age

23140-418: The military triumvirate, with Obasanjo as head of state and General Theophilus Danjuma as Chief of Army Staff , the three went on to re-establish control over the military regime and organized the military's transfer of power programme: states creation and national delimitation , local government reforms and the constitutional drafting committee for a new republic. The military carefully planned

23318-514: The monarch, the House of Commons, and the Senate . While Canada inherited the British concept of parliamentary supremacy , this was later, with the enactment of the Constitution Act, 1982, all but completely superseded by the American notion of the supremacy of the law . Each of the 338 members of Parliament in the House of Commons is elected by simple plurality in an electoral district or riding. The Constitution Act, 1982 , requires that no more than five years pass between elections, although

23496-403: The most common across the country; Sudan savannah, with short grasses and short trees; and Sahel savannah patches of grass and sand, found in the northeast. Waste management including sewage treatment , the linked processes of deforestation and soil degradation , and climate change or global warming are the major environmental problems in Nigeria. Waste management presents problems in

23674-582: The name of the national holiday was changed from Dominion Day to Canada Day . The first inhabitants of North America are generally hypothesized to have migrated from Siberia by way of the Bering land bridge and arrived at least 14,000 years ago. The Paleo-Indian archeological sites at Old Crow Flats and Bluefish Caves are two of the oldest sites of human habitation in Canada. The characteristics of Indigenous societies included permanent settlements, agriculture, complex societal hierarchies, and trading networks. Some of these cultures had collapsed by

23852-461: The new PDP (a faction of serving governors of the ruling People's Democratic Party) – formed the All Progressives Congress led by current president Bola Ahmed Tinubu. At the time, it was the most expensive election ever to be held on the African continent (being surpassed only by the elections of 2019 and 2023 ). The new mega-opposition party chose as their candidate for the election former military dictator Muhammadu Buhari. Buhari's campaign in 2015

24030-434: The new caliph. Lugard abolished the caliphate but retained the title sultan as a symbolic position in the newly organized Northern Nigeria Protectorate . This remnant became known as " Sokoto Sultanate Council ". In June 1903, the British defeated the remaining northern forces of Attahiru. By 1906, all resistance to British rule had ended. On 1 January 1914, the British formally united the Southern Nigeria Protectorate and

24208-410: The nine homogenous samples: CEU+TSI (Combined panel of Utah residents with Northern and Western European ancestry from the CEPH collection and Tuscans in Italy); JPT+CHB (Combined panel of Japanese in Tokyo, Japan and Han Chinese in Beijing, China) and JPT+CHB+CHD (Combined panel of Japanese in Tokyo, Japan, Han Chinese in Beijing, China and Chinese in Metropolitan Denver, Colorado). CEU+TSI, for instance,

24386-419: The north, the incessant fighting amongst the Hausa city-states and the decline of the Bornu Empire allowed the Fulani people to gain headway into the region. Until this point, the Fulani, a nomadic ethnic group, primarily traversed the semi-desert Sahelian region north of Sudan with cattle and avoided trade and intermingling with the Sudanic peoples. At the beginning of the 19th century, Usman dan Fodio led

24564-400: The official Nigerian government side attacked Biafra on 6 July 1967, at Garkem. The 30-month war, with a long blockade of Biafra and its isolation from trade and international relief, ended in January 1970. Estimates of the number of dead in the former Eastern Region during the 30-month civil war range from one to three million. Britain and the Soviet Union were the main military backers of

24742-538: The other SNPs in the region. Using these, genotype imputation can be used to determine (impute) the other SNPs and thus the entire haplotype with high confidence. Next, one determines the genotype for these tag SNPs in several individuals, some with the disease and some without. By comparing the two groups, one determines the likely locations and haplotypes that are involved in the disease. Haplotypes are generally shared between populations, but their frequency can differ widely. Four populations were selected for inclusion in

24920-404: The permafrost is uncertain because the Arctic has been warming at three times the global average as a result of climate change in Canada . Canada's annual average temperature over land has risen by 1.7 °C (3.1 °F), with changes ranging from 1.1 to 2.3 °C (2.0 to 4.1 °F) in various regions, since 1948. The rate of warming has been higher across the North and in the Prairies. In

25098-466: The plotters struggled to form a central government. Senate President Nwafor Orizu handed over government control to the Army , under the command of another Igbo officer, Major General Johnson Aguiyi-Ironsi . Later, the counter-coup of 1966, supported primarily by Northern military officers, facilitated the rise of Yakubu Gowon as military head of state. Tension rose between north and south; Igbos in northern cities suffered persecution and many fled to

25276-443: The protectorates. Under Britain's policy of indirect rule and validation of Islamic legitimist tradition, the Crown did not encourage the operation of Christian missions in the northern, Islamic part of the country. By the mid-20th century following World War II , a wave for independence was sweeping across Africa, in response to the growth of Nigerian nationalism and demands for independence, successive constitutions legislated by

25454-488: The provinces collect more revenue than the federal government, equalization payments are made by the federal government to ensure reasonably uniform standards of services and taxation are kept between the richer and poorer provinces. The major difference between a Canadian province and a territory is that provinces receive their sovereignty from the Crown and power and authority from the Constitution Act, 1867 , whereas territorial governments have powers delegated to them by

25632-404: The region Slave Coast . Europeans traded goods with peoples at the coast; coastal trade with Europeans also marked the beginnings of the Atlantic slave trade . The port of Calabar on the historical Bight of Biafra (now commonly referred to as the Bight of Bonny) became one of the largest slave-trading posts in West Africa in this era. Other major slaving ports were located in Badagry , Lagos on

25810-428: The resettlement of slaves freed by Britain in North America after the American Revolutionary War . Britain intervened in the Lagos kingship power struggle by bombarding Lagos in 1851, deposing the slave-trade-friendly Oba Kosoko , helping to install the amenable Oba Akitoye and signing the Treaty between Great Britain and Lagos on 1   January 1852. Britain annexed Lagos as a crown colony in August 1861 with

25988-405: The return to civilian rule putting in place measures to ensure that political parties had broader support than witnessed during the first republic. In 1979, five political parties competed in a series of elections in which Alhaji Shehu Shagari of the National Party of Nigeria (NPN) was elected president. All five parties won representation in the National Assembly. On 1 October 1979, Shehu Shagari

26166-736: The rights they support were reaffirmed by section 35 of the Constitution Act, 1982 . These rights may include provision of services, such as healthcare through the Indian Health Transfer Policy , and exemption from taxation. Canada is a federation composed of 10 federated states , called provinces, and three federal territories . These may be grouped into four main regions : Western Canada , Central Canada , Atlantic Canada , and Northern Canada ( Eastern Canada refers to Central Canada and Atlantic Canada together). Provinces and territories have responsibility for social programs such as healthcare , education , and social programs , as well as administration of justice (but not criminal law). Although

26344-480: The second millennium BC, with the Nok civilization in the 15th century BC marking the first internal unification. The modern state originated with British colonialization in the 19th century, taking its present territorial shape with the merging of the Southern Nigeria Protectorate and the Northern Nigeria Protectorate in 1914.

26878-422: The southern regions of Canada, air pollution from both Canada and the United States—caused by metal smelting, burning coal to power utilities, and vehicle emissions—has resulted in acid rain , which has severely impacted waterways, forest growth, and agricultural productivity. Canada is one of the largest greenhouse gas emitters globally , with emissions increased by 16.5 percent between 1990 and 2022. Canada

27056-438: The terms of peace, ceding British North American territories south of the Great Lakes and east of the Mississippi River to the new country. The American war of independence also caused a large out-migration of Loyalists , the settlers who had fought against American independence. Many moved to Canada, particularly Atlantic Canada, where their arrival changed the demographic distribution of the existing territories. New Brunswick

27234-403: The threshold of power in the country. As oil production and revenue rose, the Nigerian government became increasingly dependent on oil revenues and international commodity markets for budgetary and economic concerns. The coup in July 1975 , led by Generals Shehu Musa Yar'Adua and Joseph Garba , ousted Gowon, who fled to Britain. The coup plotters wanted to replace Gowon's autocratic rule with

The Indigenous population at

27590-446: The time of the first European settlements is estimated to have been between 200,000 and two million, with a figure of 500,000 accepted by Canada's Royal Commission on Aboriginal Peoples . As a consequence of European colonization, the Indigenous population declined by forty to eighty percent. The decline is attributed to several causes, including the transfer of European diseases , to which they had no natural immunity, conflicts over

27768-555: The usefulness of including additional populations in the project. All samples were collected through a community engagement process with appropriate informed consent. The community engagement process was designed to identify and attempt to respond to culturally specific concerns and give participating communities input into the informed consent and sample collection processes. In phase III, 11 global ancestry groups have been assembled: ASW (African ancestry in Southwest USA); CEU (Utah residents with Northern and Western European ancestry from

In August 1983, Shagari and the NPN were returned to power in a landslide victory, with a majority of seats in the National Assembly and control of 12 state governments. But the elections were marred by violence, and allegations of widespread vote-rigging and electoral malfeasance led to legal battles over the results. There were also uncertainties, such as in the first republic, that political leaders may be unable to govern properly. The 1983 military coup d'état

28836-419: The widespread cultivation of agricultural products, such as the palm, for use in European industry.

29192-491: The world, about two million, was concentrated in the territories of the Sokoto Caliphate . The use of slave labour was extensive, especially in agriculture. By the time of its break-up in 1903 into various European colonies, the Sokoto Caliphate was one of the largest pre-colonial African states. A changing legal imperative (the outlawing of the Atlantic slave trade in 1807) and economic imperative (a desire for political and social stability) led most European powers to support

More recent research suggests that iron metallurgy was developed independently in sub-Saharan Africa . The Nok civilization thrived between 1,500 BC and AD 200. It produced life-sized terracotta figures that are some of
