Today, all humans are classified as belonging to the species Homo sapiens and sub-species Homo sapiens sapiens. However, this is not the first species of homininae: the first species of genus Homo, Homo habilis, are theorized to have evolved in East Africa at least 2 million years ago, and members of this species populated different parts of Africa in a relatively short time. Homo erectus is theorized to have evolved more than 1.8 million years ago, and by 1.5 million years ago had spread throughout Europe and Asia. Virtually all physical anthropologists agree that Archaic Homo sapiens (A group including the possible species H. heidelbergensis, H. rhodesiensis and H. neanderthalensis) evolved out of African Homo erectus ((sensu lato) or Homo ergaster).

Even interpreting the hydrogen data (including safety data) is confounded by a number of phenomena. Many physical and chemical properties of hydrogen depend on the parahydrogen/orthohydrogen ratio (it often takes days or weeks at a given temperature to reach the equilibrium ratio, for which the data is usually given). Hydrogen detonation parameters, such as critical detonation pressure and temperature, strongly depend on the container geometry.

---

Question: How long can it take to reach the equilibrium ratio?
Answer: days or weeks.

The World Bank collects a range of data on corruption, including survey responses from over 100,000 firms worldwide and a set of indicators of governance and institutional quality. Moreover, one of the six dimensions of governance measured by the Worldwide Governance Indicators is Control of Corruption, which is defined as "the extent to which power is exercised for private gain, including both petty and grand forms of corruption, as well as 'capture' of the state by elites and private interests." While the definition itself is fairly precise, the data aggregated into the Worldwide Governance Indicators is based on any available polling: questions range from "is corruption a serious problem?" to measures of public access to information, and not consistent across countries. Despite these weaknesses, the global coverage of these datasets has led to their widespread adoption, most notably by the Millennium Challenge Corporation.

Question: Which organization is most notable for adopting the global coverage of these studies?
Answer: Millennium Challenge Corporation.

Medical detection dogs are capable of detecting diseases by sniffing a person directly or samples of urine or other specimens. Dogs can detect odour in one part per trillion, as their brain's olfactory cortex is (relative to total brain size) 40 times larger than humans. Dogs may have as many as 300 million odour receptors in their nose, while humans may have only 5 million. Each dog is trained specifically for the detection of single disease from the blood glucose level indicative to diabetes to cancer. To train a cancer dog requires 6 months. A Labrador Retriever called Daisy has detected 551 cancer patients with an accuracy of 93 percent and received the Blue Cross (for pets) Medal for her life-saving skills.

Question: How many cancer patients has Daisy detected?
Answer: 551.

The members of The Beatles were made MBEs in 1965. John Lennon justified the comparative merits of his investiture by comparing military membership in the Order: "Lots of people who complained about us receiving the MBE [status] received theirs for heroism in the war – for killing people… We received ours for entertaining other people. I'd say we deserve ours more." Lennon later returned his MBE insignia on 25 November 1969 as part of his ongoing peace protests. Other criticism centres on the claim that many recipients of the Order are being rewarded with honours for simply doing their jobs; critics claim that the civil service and judiciary receive far more orders and honours than leaders of other professions.

Question: When did John Lennon return his MBE insignia?
Answer: 25 November 1969.

Whitehead's most complete work on education is the 1929 book The Aims of Education and Other Essays, which collected numerous essays and addresses by Whitehead on the subject published between 1912 and 1927. The essay from which Aims of Education derived its name was delivered as an address in 1916 when Whitehead was president of the London Branch of the Mathematical Association. In it, he cautioned against the teaching of what he called "inert ideas" – ideas that are disconnected scraps of information, with no application to real life or culture. He opined that "education with inert ideas is not only useless: it is, above all things, harmful."

The toponym Schwyz itself is first attested in 972, as Old High German Suittes, ultimately perhaps related to suedan "to burn", referring to the area of forest that was burned and cleared to build. The name was extended to the area dominated by the canton, and after the Swabian War of 1499 gradually came to be used for the entire Confederation. The Swiss German name of the country, Schwiiz, is homophonous to that of the canton and the settlement, but distinguished by the use of the definite article (d'Schwiiz for the Confederation, but simply Schwyz for the canton and the town).

Nasser's regional position changed unexpectedly when Yemeni officers led by Nasser supporter Abdullah al-Sallal overthrew Imam Badr of North Yemen on 27 September 1962. Al-Badr and his tribal partisans began receiving increasing support from Saudi Arabia to help reinstate the kingdom, while Nasser subsequently accepted a request by Sallal to militarily aid the new government on 30 September. Consequently, Egypt became increasingly embroiled in the drawn-out civil war until it withdrew its forces in 1967. Most of Nasser's old colleagues had questioned the wisdom of continuing the war, but Amer reassured Nasser of their coming victory. Nasser later remarked in 1968 that intervention in Yemen was a "miscalculation".

The Portuguese found the island uninhabited, with an abundance of trees and fresh water. They imported livestock, fruit trees and vegetables, and built a chapel and one or two houses. Though they formed no permanent settlement, the island was an important rendezvous point and source of food for ships travelling from Asia to Europe, and frequently sick mariners were left on the island to recover, before taking passage on the next ship to call on the island.

Most Western European countries changed the start of the year to 1 January before they adopted the Gregorian calendar. For example, Scotland changed the start of the Scottish New Year to 1 January in 1600 (this means that 1599 was a short year). England, Ireland and the British colonies changed the start of the year to 1 January in 1752 (so 1751 was a short year with only 282 days) though in England the start of the tax year remained at 25 March (O.S.), 5 April (N.S.) till 1800, when it moved to 6 April. Later in 1752 in September the Gregorian calendar was introduced throughout Britain and the British colonies (see the section Adoption). These two reforms were implemented by the Calendar (New Style) Act 1750.

Richmond has a significant arts community, some of which is contained in formal public-supported venues, and some of which is more DIY, such as local privately owned galleries, and private music venues, nonprofit arts organizations, or organic and venueless arts movements (e.g., house shows, busking, itinerant folk shows). This has led to tensions, as the city Richmond City levied an "admissions tax" to fund large arts projects like CentreStage, leading to criticism that it is funding civic initiatives on the backs of the organic local culture. Traditional Virginian folk music, including blues, country, and bluegrass are also notably present, and play a large part in the annual Richmond Folk Festival. The following is a list of the more formal arts establishments (Companies, theaters, galleries, and other large venues) in Richmond:

The works of Virgil almost from the moment of their publication revolutionized Latin poetry. The Eclogues, Georgics, and above all the Aeneid became standard texts in school curricula with which all educated Romans were familiar. Poets following Virgil often refer intertextually to his works to generate meaning in their own poetry. The Augustan poet Ovid parodies the opening lines of the Aeneid in Amores 1.1.1–2, and his summary of the Aeneas story in Book 14 of the Metamorphoses, the so-called "mini-Aeneid", has been viewed as a particularly important example of post-Virgilian response to the epic genre. Lucan's epic, the Bellum Civile has been considered an anti-Virgilian epic, disposing with the divine mechanism, treating historical events, and diverging drastically from Virgilian epic practice. The Flavian poet Statius in his 12-book epic Thebaid engages closely with the poetry of Virgil; in his epilogue he advises his poem not to "rival the divine Aeneid, but follow afar and ever venerate its footsteps." In Silius Italicus, Virgil finds one of his most ardent admirers. With almost every line of his epic Punica Silius references Virgil. Indeed, Silius is known to have bought Virgil's tomb and worshipped the poet. Partially as a result of his so-called "Messianic" Fourth Eclogue—widely interpreted later to have predicted the birth of Jesus Christ—Virgil was in later antiquity imputed to have the magical abilities of a seer; the Sortes Vergilianae, the process of using Virgil's poetry as a tool of divination, is found in the time of Hadrian, and continued into the Middle Ages. In a similar vein Macrobius in the Saturnalia credits the work of Virgil as the embodiment of human knowledge and experience, mirroring the Greek conception of Homer. Virgil also found commentators in antiquity. Servius, a commentator of the 4th century AD, based his work on the commentary of Donatus. Servius' commentary provides us with a great deal of information about Virgil's life, sources, and references; however, many modern scholars find the variable quality of his work and the often simplistic interpretations frustrating.

Based on discoveries made through neural mapping of the limbic system, the neurobiological explanation of human emotion is that emotion is a pleasant or unpleasant mental state organized in the limbic system of the mammalian brain. If distinguished from reactive responses of reptiles, emotions would then be mammalian elaborations of general vertebrate arousal patterns, in which neurochemicals (for example, dopamine, noradrenaline, and serotonin) step-up or step-down the brain's activity level, as visible in body movements, gestures and postures. Emotions can likely be mediated by pheromones (see fear).

Question: What classification of chemicals do dopamine, serotonin and noradrenaline belong to?
Answer: neurochemicals.

Network effects are a large factor with electrification. When converting lines to electric, the connections with other lines must be considered. Some electrifications have subsequently been removed because of the through traffic to non-electrified lines. If through traffic is to have any benefit, time consuming engine switches must occur to make such connections or expensive dual mode engines must be used. This is mostly an issue for long distance trips, but many lines come to be dominated by through traffic from long-haul freight trains (usually running coal, ore, or containers to or from ports). In theory, these trains could enjoy dramatic savings through electrification, but it can be too costly to extend electrification to isolated areas, and unless an entire network is electrified, companies often find that they need to continue use of diesel trains even if sections are electrified. The increasing demand for container traffic which is more efficient when utilizing the double-stack car also has network effect issues with existing electrifications due to insufficient clearance of overhead electrical lines for these trains, but electrification can be built or modified to have sufficient clearance, at additional cost.

Question: What can be a drawback of electrification of long distance freight trains?
Answer: electrification to isolated areas.

Krugman's contention (that the growth of a commercial real estate bubble indicates that U.S. housing policy was not the cause of the crisis) is challenged by additional analysis. After researching the default of commercial loans during the financial crisis, Xudong An and Anthony B. Sanders reported (in December 2010): "We find limited evidence that substantial deterioration in CMBS [commercial mortgage-backed securities] loan underwriting occurred prior to the crisis." Other analysts support the contention that the crisis in commercial real estate and related lending took place after the crisis in residential real estate. Business journalist Kimberly Amadeo reports: "The first signs of decline in residential real estate occurred in 2006. Three years later, commercial real estate started feeling the effects. Denice A.

Fryderyk's father, Nicolas Chopin, was a Frenchman from Lorraine who had emigrated to Poland in 1787 at the age of sixteen. Nicolas tutored children of the Polish aristocracy, and in 1806 married Justyna Krzyżanowska, a poor relative of the Skarbeks, one of the families for whom he worked. Fryderyk was baptized on Easter Sunday, 23 April 1810, in the same church where his parents had married, in Brochów. His eighteen-year-old godfather, for whom he was named, was Fryderyk Skarbek, a pupil of Nicolas Chopin. Fryderyk was the couple's second child and only son; he had an elder sister, Ludwika (1807–55), and two younger sisters, Izabela (1811–81) and Emilia (1812–27). Nicolas was devoted to his adopted homeland, and insisted on the use of the Polish language in the household.

The Czechs' language separated from other Slavic tongues into what would later be called Old Czech by the thirteenth century, a classification extending through the sixteenth century. Its use of cases differed from the modern language; although Old Czech did not yet have a vocative case or an animacy distinction, declension for its six cases and three genders rapidly became complicated (partially to differentiate homophones) and its declension patterns resembled those of Lithuanian (its Balto-Slavic cousin).

Although Bell was, and still is, accused of stealing the telephone from Gray, Bell used Gray's water transmitter design only after Bell's patent had been granted, and only as a proof of concept scientific experiment, to prove to his own satisfaction that intelligible "articulate speech" (Bell's words) could be electrically transmitted. After March 1876, Bell focused on improving the electromagnetic telephone and never used Gray's liquid transmitter in public demonstrations or commercial use.

The concept of racial origin relies on the notion that human beings can be separated into biologically distinct "races", an idea generally rejected by the scientific community. Since all human beings belong to the same species, the ECRI (European Commission against Racism and Intolerance) rejects theories based on the existence of different "races". However, in its Recommendation ECRI uses this term in order to ensure that those persons who are generally and erroneously perceived as belonging to "another race" are not excluded from the protection provided for by the legislation. The law claims to reject the existence of "race", yet penalize situations where someone is treated less favourably on this ground.

Presbyterian denominations that trace their heritage to the British Isles usually organise their church services inspired by the principles in the Directory of Public Worship, developed by the Westminster Assembly in the 1640s. This directory documented Reformed worship practices and theology adopted and developed over the preceding century by British Puritans, initially guided by John Calvin and John Knox. It was enacted as law by the Scottish Parliament, and became one of the foundational documents of Presbyterian church legislation elsewhere.

Dietary minerals are inorganic chemical elements required by living organisms, other than the four elements carbon, hydrogen, nitrogen, and oxygen that are present in nearly all organic molecules. The term "mineral" is archaic, since the intent is to describe simply the less common elements in the diet. Some are heavier than the four just mentioned, including several metals, which often occur as ions in the body. Some dietitians recommend that these be supplied from foods in which they occur naturally, or at least as complex compounds, or sometimes even from natural inorganic sources (such as calcium carbonate from ground oyster shells). Some minerals are absorbed much more readily in the ionic forms found in such sources. On the other hand, minerals are often artificially added to the diet as supplements; the most famous is likely iodine in iodized salt which prevents goiter.

Question: What was the term "mineral" originally meant to describe?
Answer: the less common elements in the diet.

Birds have been domesticated by humans both as pets and for practical purposes. Colourful birds, such as parrots and mynas, are bred in captivity or kept as pets, a practice that has led to the illegal trafficking of some endangered species. Falcons and cormorants have long been used for hunting and fishing, respectively. Messenger pigeons, used since at least 1 AD, remained important as recently as World War II. Today, such activities are more common either as hobbies, for entertainment and tourism, or for sports such as pigeon racing.

Personnel Recovery (PR) is defined as "the sum of military, diplomatic, and civil efforts to prepare for and execute the recovery and reintegration of isolated personnel" (JP 1-02). It is the ability of the US government and its international partners to effect the recovery of isolated personnel across the ROMO and return those personnel to duty. PR also enhances the development of an effective, global capacity to protect and recover isolated personnel wherever they are placed at risk; deny an adversary's ability to exploit a nation through propaganda; and develop joint, interagency, and international capabilities that contribute to crisis response and regional stability.
