Northern Canada
–
Northern Canada, colloquially the North, is the vast northernmost region of Canada variously defined by geography and politics. Politically, the term refers to three territories of Canada, Yukon, Northwest Territories, and Nunavut, similarly, the Far North may refer to the Canadian Arctic, the portion of Canada north of the Arctic Circle and lies east of Alaska and west of Greenland. This area covers about 39 percent of Canadas total land area, for some purposes, Northern Canada may also include Northern Quebec and Northern Labrador. These reckonings somewhat depend on the concept of nordicity, a measure of so-called northernness that other Arctic territories share. Canada is the northernmost country in the Americas and roughly 80% of its 35 million inhabitants are concentrated along its border with the United States. Combined with the fact that all of the country experiences severely cold winters along with short and relatively cool summers. Due to the concentration of its population along the border. Southern Canada is therefore considered to be a region only when it is contrasted against or viewed from the North, as a social rather than political region, the Canadian north is often subdivided into two distinct regions based on climate, the near north and the far north. The different climates of these two regions result in different vegetation, and therefore very different economies, settlement patterns. The near north or subarctic is mostly synonymous with the Canadian boreal forest and this area has traditionally been home to the Indigenous peoples of the Subarctic, that is the First Nations, who were hunters of moose, freshwater fishers and trappers. This region was involved in the North American fur trade during its peak importance. The area was part of Ruperts Land or the North-Western Territory under the nominal control of the Hudsons Bay Company from 1670–1869. The HBCs claim was purchased by the Canadian government in 1869 and this opened the region to non-Native settlement, as well as to forestry, mining, and oil and gas drilling. Today several million people live in the north, around 15% of the Canadian total. The far north is synonymous with the north of the tree line. This area is home to the various sub-groups of the Inuit and these are people who have traditionally relied mostly on hunting marine mammals and caribou, mainly barren-ground caribou, as well as fish and migratory birds. This area was somewhat involved in the fur trade, but was influenced by the whaling industry. Very few non-Aboriginal people have settled in areas, and the residents of the far north represent less than 1% of Canadas total population

Queen Elizabeth Islands
–
The Queen Elizabeth Islands are the northernmost cluster of islands in the Canadian Arctic Archipelago, split between Nunavut and Northwest Territories in Northern Canada. The Queen Elizabeth Islands contain approximately 14% of the global glacier, the islands, together 419,061 km2 in area, were renamed as a group after Elizabeth II on her coronation as Queen of Canada in 1953. The islands cover an area approximating to the shape of a triangle, bounded by the Nares Strait on the east, Parry Channel on the south. Most are uninhabited although the Natural Resources Canadas Climate Change Geoscience Program Earth Sciences Sector, has monitors on the islands. In 1969 Panarctic Oils, now part of Suncor began operating exploration oil wells in the Sverdrup and Franklinian basins and it ceased production in the 1970s. At the 2013 GeoConvention the Arctic Islands region were called Canadas perpetual last petroleum exploration frontier and these islands were known as the Parry Archipelago for over 130 years. They were first named after British Arctic explorer Sir William Parry, since the renaming of the archipelago in 1953, the term Parry Islands continued to be used for its southwestern part. The regional break down of the archipelago is therefore as follows, Ellesmere Island Sverdrup Islands Parry Islands Ellesmere Island is the northernmost, the Sverdrup Islands are located west of Ellesmere Island and north of Norwegian Bay. South of Lancaster Sound, Viscount Melville Sound and McClure Strait are the islands of the Canadian Arctic Archipelago. Many of the islands are among the largest in the world and they consist of Silurian and Carboniferous rocks covered with tundra. With a population of less than 400, the islands are nearly uninhabited, there are only three permanently inhabited places in the islands. The two municipalities are the hamlets of Resolute, on Cornwallis Island, and Grise Fiord, on Ellesmere Island, eureka, a small research base on Ellesmere Island, has a population of zero but at least 8 staff on a continuous rotational basis. Abandoned Permanent Settlement Seasonally Occupied Formerly manned stations were Mould Bay on Prince Patrick Island, Isachsen on Ellef Ringnes Island, abandoned settlements are Dundas Harbour on Devon Island and Craig Harbour on Ellesmere Island. Until 1999, the Queen Elizabeth Islands were part of the Baffin Region of the Northwest Territories, the rest remained with the now-reduced Northwest Territories. Borden Island, Mackenzie King Island and Melville Island were divided between the two territories, Prince Patrick Island, Eglinton Island and Emerald Island are the only notable islands that are now completely part of the Northwest Territories. Below the level of the territory, there is the level of administration. On that level, there are two municipalities, Resolute and Grise Fiord, with an aggregate area of 450 km2. The remaining 99.89 percent are unincorporated area, with a census 2006 population of five, according to the Atlas of Canada there are 34 larger and 2,092 smaller islands in the archipelago

Canada
–
Canada is a country in the northern half of North America. Canadas border with the United States is the worlds longest binational land border, the majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its territory being dominated by forest and tundra. It is highly urbanized with 82 per cent of the 35.15 million people concentrated in large and medium-sized cities, One third of the population lives in the three largest cities, Toronto, Montreal and Vancouver. Its capital is Ottawa, and other urban areas include Calgary, Edmonton, Quebec City, Winnipeg. Various aboriginal peoples had inhabited what is now Canada for thousands of years prior to European colonization. Pursuant to the British North America Act, on July 1,1867, the colonies of Canada, New Brunswick and this began an accretion of provinces and territories to the mostly self-governing Dominion to the present ten provinces and three territories forming modern Canada. With the Constitution Act 1982, Canada took over authority, removing the last remaining ties of legal dependence on the Parliament of the United Kingdom. Canada is a parliamentary democracy and a constitutional monarchy, with Queen Elizabeth II being the head of state. The country is officially bilingual at the federal level and it is one of the worlds most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Its advanced economy is the eleventh largest in the world, relying chiefly upon its abundant natural resources, Canadas long and complex relationship with the United States has had a significant impact on its economy and culture. Canada is a country and has the tenth highest nominal per capita income globally as well as the ninth highest ranking in the Human Development Index. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, Canada is an influential nation in the world, primarily due to its inclusive values, years of prosperity and stability, stable economy, and efficient military. While a variety of theories have been postulated for the origins of Canada. In 1535, indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona, from the 16th to the early 18th century Canada referred to the part of New France that lay along the St. Lawrence River. In 1791, the area became two British colonies called Upper Canada and Lower Canada collectively named The Canadas, until their union as the British Province of Canada in 1841. Upon Confederation in 1867, Canada was adopted as the name for the new country at the London Conference. The transition away from the use of Dominion was formally reflected in 1982 with the passage of the Canada Act, later that year, the name of national holiday was changed from Dominion Day to Canada Day

Provinces and territories of Canada
–
Canadas geography is divided into administrative divisions known as provinces and territories that are responsible for delivery of sub-national governance. Over its history, Canadas international borders have changed several times, the ten provinces are Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, Quebec, and Saskatchewan. Several of the provinces were former British colonies, Quebec was originally a French colony, the three territories are Northwest Territories, Nunavut, and Yukon, which govern the rest of the area of the former British North America. Together, the provinces and territories make up the worlds second-largest country by area, the powers flowing from the Constitution Act are divided between the federal government and the provincial governments to exercise exclusively. In modern Canadian constitutional theory, the provinces are considered to be co-sovereign divisions, the territories are not sovereign, but simply part of the federal realm, and have a commissioner who represents the federal government. Notes, There are three territories in Canada, unlike the provinces, the territories of Canada have no inherent sovereignty and have only those powers delegated to them by the federal government. They include all of mainland Canada north of latitude 60° north and west of Hudson Bay, the following table lists the territories in order of precedence. Prior to Confederation, Ontario and Quebec were united as the Province of Canada, over the following years, Manitoba, British Columbia, and Prince Edward Island were added as provinces. The Hudsons Bay Company controlled large swathes of western Canada referred to as Ruperts Land and the North-Western Territory until 1870, subsequently, the area was re-organized into the province of Manitoba and the Northwest Territories. The remaining Arctic islands were transferred by Britain to Canada in 1880,1898 saw the Yukon Territory, later renamed simply as Yukon, carved from the parts of the Northwest Territories surrounding the Klondike gold fields. On September 1,1905, a portion of the Northwest Territories south of the 60th parallel north became the provinces of Alberta and Saskatchewan. In 1912, the boundaries of Quebec, Ontario and Manitoba were expanded northward, Manitobas to the 60° parallel, Ontarios to Hudson Bay, in 1907, Newfoundland acquired dominion status. In the middle of the Great Depression in Canada with Newfoundland facing a period of economic crisis. In 2001, it was officially renamed Newfoundland and Labrador, in 1903, the Alaska Panhandle Dispute fixed British Columbias northwestern boundary. This was one of two provinces in Canadian history to have its size reduced. In 1999, Nunavut was created from the portion of the Northwest Territories. Yukon lies in the portion of The North, while Nunavut is in the east. All three territories combined are the most sparsely populated region in Canada, covering 3,921,739 km2 in land area and they are often referred to as a single region, The North, for organisational and economic purposes

Northwest Territories
–
The Northwest Territories is a territory of Canada. At a land area of approximately 1,144,000 km2 and its estimated population as of 2016 is 44,291. Yellowknife became the capital in 1967, following recommendations by the Carrothers Commission. The Northwest Territories are bordered by Canadas two other territories, Nunavut to the east and Yukon to the west, and by the provinces of British Columbia, Alberta, and Saskatchewan to the south. The name is descriptive, adopted by the British government during the era to indicate where it lay in relation to Ruperts Land. It is shortened from North-Western Territory, in Inuktitut, the Northwest Territories are referred to as ᓄᓇᑦᓯᐊᖅ, beautiful land. There was some discussion of changing the name of the Northwest Territories after the splitting off of Nunavut, one proposal was Denendeh, as advocated by the former premier Stephen Kakfwi, among others. One of the most popular proposals for a new name – one to name the territory Bob – began as a prank, in the end a poll conducted prior to division showed that strong support remained to keep the name Northwest Territories. This name arguably became more appropriate following division than it had been when the territories extended far into Canadas north-central and it possibly meets Manitoba at a quadripoint to the extreme southeast, though surveys have not been completed. It has an area of 1,183,085 km2. Territorial islands in the Canadian Arctic Archipelago include Banks Island, Borden Island, Prince Patrick Island and its highest point is Mount Nirvana near the border with Yukon at an elevation of 2,773 m. The Northwest Territories extends for more than 1,300,000 km2 and has a large climate variant from south to north, the southern part of the territory has a subarctic climate, while the islands and northern coast have a polar climate. Summers in the north are short and cool, with highs in the mid teens Celsius. Winters are long and harsh, daytime highs in the mid −20 °C, extremes are common with summer highs in the south reaching 36 °C and lows reaching into the negatives. In winter in the south, it is not uncommon for the temperatures to reach −40 °C, in the north, temperatures can reach highs of 30 °C, and lows can reach into the low negatives. In winter in the north it is not uncommon for the temperatures to reach −50 °C, thunderstorms are not rare in the south. In the north they are rare, but do occur. Tornadoes are extremely rare but have happened with the most notable one happening just outside Yellowknife that destroyed a communications tower, the Territory has a fairly dry climate due to the mountains in the west

Nunavut
–
Nunavut is the newest, largest, and northernmost territory of Canada. The creation of Nunavut resulted in the first major change to Canadas political map since the incorporation of the province of Newfoundland, Nunavut comprises a major portion of Northern Canada, and most of the Canadian Arctic Archipelago. Its vast territory makes it the fifth-largest country subdivision in the world, the capital Iqaluit, on Baffin Island in the east, was chosen by the 1995 capital plebiscite. Other major communities include the regional centres of Rankin Inlet and Cambridge Bay and it is Canadas only geo-political region that is not connected to the rest of North America by highway. Nunavut is the largest in area and the second least populous of Canadas provinces and territories. One of the worlds most remote, sparsely settled regions, it has a population of 35,944, mostly Inuit, spread over an area of just over 1,750,000 km2, Nunavut is also home to the worlds northernmost permanently inhabited place, Alert. A weather station farther down Ellesmere Island, Eureka, has the lowest average temperature of any Canadian weather station. Nunavut means our land in Inuktitut, Nunavut covers 1,877,787 km2 of land and 160,935 km2 of water in Northern Canada. This makes it the fifth largest subnational entity in the world, if Nunavut were a country, it would rank 15th in area. It also shares borders with Greenland and the provinces of Quebec, Ontario. Nunavuts highest point is Barbeau Peak on Ellesmere Island, the population density is 0.019 persons/km2, one of the lowest in the world. By comparison, Greenland has approximately the area and nearly twice the population. Nunavut experiences a climate in most regions, owing to its high latitude. In more southerly continental areas very cold climates can be found. The region now known as Nunavut has supported an indigenous population for approximately 4,000 years. Most historians identify the coast of Baffin Island with the Helluland described in Norse sagas, the materials were collected in five seasons of excavation at Cape Tanfield. Scholars determined that these provide evidence of European traders and possibly settlers on Baffin Island and they seem to indicate prolonged contact, possibly up to 1450. So you have to consider the possibility that as remote as it may seem, the ore turned out to be worthless, but Frobisher made the first recorded European contact with the Inuit

Moss
–
Mosses are small flowerless plants that typically grow in dense green clumps or mats, often in damp or shady locations. Although some species have conducting tissues, these are poorly developed. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores and they are typically 0. 2–10 cm tall, though some species are much larger. Dawsonia, the tallest moss in the world, can grow to 50 cm in height, mosses are commonly confused with lichens, hornworts, and liverworts. Lichens may superficially look like mosses, and have names that include the word moss. This contrasts with the pattern in all plants, where the diploid sporophyte generation is dominant. Mosses are now classified on their own as the division Bryophyta, the main commercial significance of mosses is as the main constituent of peat, although they are also used for decorative purposes, such as in gardens and in the florist trade. Traditional uses of mosses included as insulation and for the ability to absorb liquids up to 20 times their weight, botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are small plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide. They differ from plants in lacking water-bearing xylem tracheids or vessels. As in liverworts and hornworts, the gametophyte generation is the dominant phase of the life cycle. This contrasts with the pattern in all plants, where the diploid sporophyte generation is dominant. Mosses reproduce using spores, not seeds, and have no flowers, Moss gametophytes have stems which may be simple or branched and upright or prostrate. Their leaves are simple, usually only a layer of cells with no internal air spaces. They do not have roots, but have threadlike rhizoids that anchor them to their substrate. Mosses do not absorb water or nutrients from their substrate through their rhizoids and they can be distinguished from liverworts by their multi-cellular rhizoids. Spore-bearing capsules or sporangia of mosses are borne singly on long, unbranched stems, thereby distinguishing them from the polysporangiophytes, the spore-bearing sporophytes are short-lived and dependent on the gametophyte for water supply and nutrition. Also, in most mosses, the capsule enlarges and matures after its stalk elongates

Lichen
–
A lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi in a symbiotic relationship. The combined lichen has properties different from those of its component organisms, Lichens come in many colours, sizes, and forms. The properties are sometimes plant-like, but lichens are not plants, Lichens may have tiny, leafless branches, flat leaf-like structures, flakes that lie on the surface like peeling paint, or other growth forms. A macrolichen is a lichen that is either bush-like or leafy, here, macro and micro do not refer to size, but to the growth form. Common names for lichens may contain the word moss, and lichens may superficially look like and grow with mosses, Lichens do not have roots that absorb water and nutrients as plants do, but like plants, they produce their own food by photosynthesis. When they grow on plants, they do not live as parasites, Lichens occur from sea level to high alpine elevations, in many environmental conditions, and can grow on almost any surface. Lichens are abundant growing on bark, leaves, mosses, on other lichens and they grow on rock, walls, gravestones, roofs, exposed soil surfaces, and in the soil as part of a biological soil crust. Different kinds of lichens have adapted to survive in some of the most extreme environments on Earth, arctic tundra, hot dry deserts, rocky coasts and they can even live inside solid rock, growing between the grains. It is estimated that 6% of Earths land surface is covered by lichen, there are about 20,000 known species of lichens. Some lichens have lost the ability to reproduce sexually, yet continue to speciate, Lichens may be long-lived, with some considered to be among the oldest living things. They are among the first living things to grow on fresh rock exposed after an event such as a landslide, the long life-span and slow and regular growth rate of some lichens can be used to date events. In American English, lichen is pronounced the same as the verb liken, in British English, both this pronunciation and one rhyming with kitchen /ˈlɪtʃən/) are used. Lichens grow in a range of shapes and forms. The shape of a lichen is determined by the organization of the fungal filaments. The nonreproductive tissues, or vegetative body parts, is called the thallus, Lichens are grouped by thallus type, since the thallus is usually the most visually prominent part of the lichen. Thallus growth forms typically correspond to a few basic internal structure types, Common names for lichens often come from a growth form or color that is typical of a lichen genus. When a crustose lichen gets old, the center may start to crack up like old-dried paint, old-broken asphalt paving and this is called being rimose or areolate, and the island pieces separated by the cracks are called areolas. The areolas appear separated, but are connected by an underlying prothallus or hypothallus, when a crustose lichen grows from a center and appears to radiate out, it is called crustose placodioid

Poaceae
–
Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses. Poaceae includes the cereal grasses, bamboos and the grasses of natural grassland and cultivated lawns, Grasses have stems that are hollow except at the nodes and narrow alternate leaves borne in two ranks. The lower part of each leaf encloses the stem, forming a leaf-sheath, with ca 780 genera and around 12,000 species, Poaceae are the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. Grasslands such as savannah and prairie grasses are dominant are estimated to constitute 40. 5% of the land area of the Earth, excluding Greenland. Grasses are also an important part of the vegetation in many habitats, including wetlands, forests. Though commonly called grasses, seagrasses, rushes, and sedges fall outside this family, the rushes and sedges are related to the Poaceae, being members of the order Poales, but the seagrasses are members of order Alismatales. The name Poaceae was given by John Hendley Barnhart in 1895, based on the tribe Poeae described in 1814 by Robert Brown, the term is derived from the Ancient Greek πόα. Grasses include some of the most versatile plant life-forms, a cladogram shows subfamilies and approximate species numbers in brackets, Before 2005, fossil findings indicated that grasses evolved around 55 million years ago. Recent findings of grass-like phytoliths in Cretaceous dinosaur coprolites have pushed this back to 66 million years ago. In 2011, revised dating of the origins of the rice tribe Oryzeae suggested a date as early as 107 to 129 Mya, a multituberculate mammal with grass-eating adaptations seems to suggest that grasses were already around at 120 mya. This separation occurred within the short time span of about 4 million years. Grass leaves are always alternate and distichous, and have parallel veins. Each leaf is differentiated into a lower sheath hugging the stem, the leaf blades of many grasses are hardened with silica phytoliths, which discourage grazing animals, some, such as sword grass, are sharp enough to cut human skin. A membranous appendage or fringe of hairs called the ligule lies at the junction between sheath and blade, preventing water or insects from penetrating into the sheath, flowers of Poaceae are characteristically arranged in spikelets, each having one or more florets. The spikelets are further grouped into panicles or spikes, the part of the spikelet that bears the florets is called the rachilla. A spikelet consists of two bracts at the base, called glumes, followed by one or more florets, a floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The flowers are usually hermaphroditic—maize being an important exception—and anemophilous or wind-pollinated, the perianth is reduced to two scales, called lodicules, that expand and contract to spread the lemma and palea, these are generally interpreted to be modified sepals. This complex structure can be seen in the image on the right, the fruit of grasses is a caryopsis, in which the seed coat is fused to the fruit wall
10.
Cyperaceae
–
The Cyperaceae are a family of monocotyledonous graminoid flowering plants known as sedges, which superficially resemble grasses and rushes. The family is large, with some 5,500 known species described in about 90 genera and these species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be growing in almost all environments, many are associated with wetlands. Ecological communities dominated by sedges are known as sedgelands, features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections and leaves that are spirally arranged in three ranks. Some well-known sedges include the chestnut and the papyrus sedge. This family also includes cotton-grass, spike-rush, sawgrass, nutsedge or nutgrass, and white star sedge
11.
Polar bear
–
The polar bear is a carnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a bear, approximately the same size as the omnivorous Kodiak bear. A boar weighs around 350–700 kg, while a sow is about half that size, although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means maritime bear and derives from this fact, Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of expected habitat loss caused by change, the polar bear is classified as a vulnerable species. For decades, large-scale hunting raised international concern for the future of the species, for thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of circumpolar peoples, and polar bears remain important in their cultures. Constantine John Phipps was the first to describe the polar bear as a species in 1774. He chose the scientific name Ursus maritimus, the Latin for maritime bear, the Inuit refer to the animal as nanook. The Yupik also refer to the bear as nanuuk in Siberian Yupik, the bear is umka in the Chukchi language. In Russian, it is usually called бе́лый медве́дь, though a word still in use is ошку́й. In the Norwegian-administered Svalbard archipelago, the bear is referred to as Isbjørn. The polar bear was considered to be in its own genus. The bear family, Ursidae, is thought to have split off from other carnivorans about 38 million years ago, the Ursinae subfamily originated approximately 4.2 million years ago. The oldest known polar bear fossil is a 130,000 to 110, 000-year-old jaw bone, fossils show that between 10,000 and 20,000 years ago, the polar bears molar teeth changed significantly from those of the brown bear. Polar bears are thought to have diverged from a population of bears that became isolated during a period of glaciation in the Pleistocene or from the eastern part of Siberia. The evidence from DNA analysis is more complex, the mitochondrial DNA of the polar bear diverged from the brown bear, Ursus arctos, roughly 150,000 years ago. The mtDNA of extinct Irish brown bears is particularly close to polar bears, when the polar bear was originally documented, two subspecies were identified, Ursus maritimus maritimus by Constantine J. Phipps in 1774, and Ursus maritimus marinus by Peter Simon Pallas in 1776. This distinction has since been invalidated, one alleged fossil subspecies has been identified, Ursus maritimus tyrannus became extinct during the Pleistocene
12.
Muskox
–
This musky odor is used to attract females during mating season. Its Inuktitut name umingmak translates to the bearded one. Muskoxen primarily live in the Canadian Arctic and Greenland, with introduced populations in Sweden, Siberia, Norway. As members of the subfamily Caprinae of the family Bovidae, muskoxen are more related to sheep and goats than to oxen, however, they are placed in their own genus. The muskox is one of the two largest extant members of Caprinae, along with the similarly sized takin, instead, the muskoxs closest living relatives appear to be the gorals of the genus Naemorhedus, nowadays common in many countries of central and east Asia. The vague similarity between takin and muskox must therefore be considered an example of convergent evolution, the modern muskox is the last member of a line of ovibovines that first evolved in temperate regions of Asia and adapted to a cold tundra environment late in its evolutionary history. Later migration waves of Asian ungulates that included high-horned muskoxen reached Europe, Euceratherium was larger yet more lightly built than modern muskoxen, looking like a giant sheep with massive horns, and preferred hilly grasslands. A genus with horns, Soergelia, inhabited Eurasia in the early Pleistocene, from Spain to Siberia. The low-horned Praeovibos was present in Europe and the Mediterranean 1.5 million years ago, colonized Alaska, Praeovibos was a highly adaptable animal that appears associated with cold tundra and temperate woodland faunas alike. It is debated, however, if Praeovibos was directly ancestral to Ovibos, modern Ovibos appeared in Germany almost one million years ago and was common in the region through the Pleistocene. By the Mindel, muskoxen had also reached the British Isles, likewise, the muskox is known to have survived in Britain during warm interglacial periods. After migrating south during one of the periods of the Illinoian glaciation. The muskox was already present in its current stronghold of Banks Island 34,000 years ago, but the existence of other ice-free areas in the Canadian Arctic Archipelago at the time is disputed. Along with the bison and the pronghorn, the muskox was one of a few species of Pleistocene megafauna in North America to survive the Pleistocene/Holocene extinction event, the muskox is thought to have been able to survive the Last glacial period by finding ice-free areas away from prehistoric peoples. Fossil DNA evidence suggests that muskoxen were not only more geographically widespread during the Pleistocene, during that time, other populations of muskoxen lived across the Arctic, from the Ural Mountains to Greenland. By contrast, the current genetic makeup of the species is more homogenous, both male and female muskoxen have long, curved horns. Muskoxen stand 1.1 to 1.5 m high at the shoulder, with females measuring 135 to 200 cm in length, the small tail, often concealed under a layer of fur, measures only 10 cm long. Adults, on average, weigh 285 kg and range from 180 to 410 kg, the thick coat and large head suggests a larger animal than the muskox truly is, the bison, to which the muskox is often compared, can weigh up to twice as much. However, heavy zoo-kept specimens have weighed up to 650 kg and their coat, a mix of black, gray, and brown, includes long guard hairs that almost reach the ground
