Repopulate
Repopulation is the phenomenon of increasing the numerical size of human inhabitants or organisms of a particular species after they had almost gone extinct. Organisms An example of an organism that has repopulated after being on the brink of extinction is the Dryococelus australis. Humans The repopulation of humans after a catastrophic event is a hypothetical concept that sometimes features in fictional as well as traditional literature. In this scenario, only two members of the opposite sex are survivors after some sort of calamity that has happened. This couple, the last two humans on Earth, ends up reproducing and their offspring reproduce with one another, until after a certain amount of time, the planet Earth has a sizeable number of people.

Dryococelus Australis
''Dryococelus australis'', commonly known as the Lord Howe Island stick insect or tree lobster, is a species of stick insect that lives on the Lord Howe Island Group. It is the only member of the monotypic genus ''Dryococelus''. Thought to be extinct by 1920, it was rediscovered in 2001. It is extirpated in its largest former habitat, Lord Howe Island, and has been called "the rarest insect in the world", as the rediscovered population consisted of 24 individuals living on the small islet of Ball's Pyramid. Anatomy and behaviour Adult Lord Howe Island stick insects can measure up to in length and weigh , with males 25% smaller than females. They are oblong in shape and have sturdy legs. Males have thicker thighs than females. Unlike most phasmida, the insects have no wings. The behaviour of this stick insect is highly unusual for an insect species, in that the males and females form a bond in some pairs. The females lay eggs while hanging from branches. Hatching can happen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypothetical
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research in a process beginning with an educated guess or thought. A different meaning of the term ''hypothesis'' is used in formal logic, to denote the antecedent of a proposition; thus in the proposition "If ''P'', then ''Q''", ''P'' denotes the hypothesis (or antecedent); ''Q'' can be called a consequent. ''P'' is the assumption in a (possibly counterfactual) ''What If'' question. The adjective ''hypothetical'', meaning "havin ...

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armageddon
According to the Book of Revelation in the New Testament of the Christian Bible, Armageddon (, from grc, Ἁρμαγεδών ''Harmagedōn'', Late Latin: , from Hebrew: ''Har Məgīddō'') is the prophesied location of a gathering of armies for a battle during the end times, which is variously interpreted as either a literal or a symbolic location. The term is also used in a generic sense to refer to any end of the world scenario. In Islamic theology, Armageddon is also mentioned in Hadith as the Greatest Armageddon or Al-Malhama Al-Kubra (the great battle). The "mount" of Megiddo in northern Israel is not actually a mountain, but a tell (a mound or hill created by many generations of people living and rebuilding on the same spot) on which ancient forts were built to guard the Via Maris, an ancient trade route linking Egypt with the northern empires of Syria, Anatolia and Mesopotamia. Megiddo was the location of various ancient battles, including one in the 15th century B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Deluge
A flood myth or a deluge myth is a myth in which a great flood, usually sent by a deity or deities, destroys civilization, often in an act of divine retribution. Parallels are often drawn between the flood waters of these myths and the primaeval waters which appear in certain creation myths, as the flood waters are described as a measure for the cleansing of humanity, in preparation for rebirth. Most flood myths also contain a culture hero, who "represents the human craving for life". The flood-myth motif occurs in many cultures, including the Mesopotamian flood stories, Native American in North America, the Genesis flood narrative, ''manvantara-sandhya'' in Hinduism, and Deucalion and Pyrrha in Greek mythology. Mythologies One example of a flood myth is the ''Epic of Gilgamesh''. Many scholars believe that this account was copied from the Akkadian ''Atra-Hasis'', which dates to the 18th century BCE. In the Gilgamesh flood myth, the highest god, Enlil, decides to destro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Repoblación
The ''Repoblación'' (, ; pt, Repovoação, ) was the ninth-century repopulating of a large region between the River Duero and the Cantabrian Mountains, which had been depopulated in the early years of the Reconquista. In the reign of Alfonso I of Asturias (739–757), through a series of successful military campaigns against the Moors, the Christians had retaken Galicia, La Rioja, and León and brought the population of the northern regions firmly under their control. This left those provinces largely empty of human settlement and created a buffer zone between Moors and Christians. This region was called the ''Desert of the Duero''. This zone was left untouched for almost a century while Alfonso's successors focused their energies on Vasconia and Galicia. It was during the reign of Ordoño I of Asturias (850–866) that the repopulation of the uninhabited zone began. Ordoño began advancing to the south, repopulating the cities of Tui, Astorga, León, and Amaya. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Population
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations. Ecology In ecology, a population is a group of organisms of the same species who inhabit the same particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with in ...
