Sibling Rivalry
Sibling rivalry is a type of competition or animosity among siblings, whether blood-related or not. Siblings generally spend more time together during childhood than they do with parents. The sibling bond is often complicated and is influenced by factors such as parental treatment, birth order, personality, and people and experiences outside the family. Sibling rivalry is particularly intense when children are very close in age and of the same gender and/or where one or both children are intellectually gifted. Throughout the lifespan According to observational studies by Judith Dunn, children are sensitive from the age of one year to differences in parental treatment. From 18 months, siblings can understand family rules and know how to comfort and be kind to each other. By the age of 3, children have a sophisticated grasp of social rules, can evaluate themselves in relation to their siblings, and know how to adapt to circumstances within the family. Sibling rivalry often cont ...

Competition
Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game). Competition can arise between entities such as organisms, individuals, economic and social groups, etc. The rivalry can be over attainment of any exclusive goal, including recognition: Competition occurs in nature, between living organisms which co-exist in the same environment. Animals compete over water supplies, food, mates, and other biological resources. Humans usually compete for food and mates, though when these needs are met deep rivalries often arise over the pursuit of wealth, power, prestige, and fame when in a static, repetitive, or unchanging environment. Competition is a major tenet of market economies and business, often associated with business competition as companies are in competition with at least one other firm over the same group of customers. Competition inside a company is ...

Cain And Abel
In the biblical Book of Genesis, Cain ''Qayīn'', in pausa ''Qāyīn''; gr, Κάϊν ''Káïn''; ar, قابيل/قايين, Qābīl / Qāyīn and Abel ''Heḇel'', in pausa ''Hāḇel''; gr, Ἅβελ ''Hábel''; ar, هابيل, Hābīl are the first two sons of Adam and Eve. Cain, the firstborn, was a farmer, and his brother Abel was a shepherd. The brothers made sacrifices to God, but God favored Abel's sacrifice instead of Cain's. Cain then murdered Abel, whereupon God punished Cain by condemning him to a life of wandering. Cain then dwelt in the land of Nod (), where he built a city and fathered the line of descendants beginning with Enoch. Genesis narrative The story of Cain's murder of Abel and its consequences is told in : Translation notes Origins Etymology Cain and Abel are traditional English renderings of the Hebrew names. It has been proposed that the etymology of their names may be a direct pun on the roles they take in the Genesis nar ...

Bible
The Bible (from Koine Greek , , 'the books') is a collection of religious texts or scriptures that are held to be sacred in Christianity, Judaism, Samaritanism, and many other religions. The Bible is an anthologya compilation of texts of a variety of forms originally written in Hebrew, Aramaic, and Koine Greek. These texts include instructions, stories, poetry, and prophecies, among other genres. The collection of materials that are accepted as part of the Bible by a particular religious tradition or community is called a biblical canon. Believers in the Bible generally consider it to be a product of divine inspiration, but the way they understand what that means and interpret the text can vary. The religious texts were compiled by different religious communities into various official collections. The earliest contained the first five books of the Bible. It is called the Torah in Hebrew and the Pentateuch (meaning ''five books'') in Greek; the second oldest part ...

Book Of Genesis
The Book of Genesis (from Greek ; Hebrew: בְּרֵאשִׁית ''Bəreʾšīt'', "In hebeginning") is the first book of the Hebrew Bible and the Christian Old Testament. Its Hebrew name is the same as its first word, ( "In the beginning"). Genesis is an account of the creation of the world, the early history of humanity, and of Israel's ancestors and the origins of the Jewish people. Tradition credits Moses as the author of Genesis, as well as the books of Exodus, Leviticus, Numbers and most of Deuteronomy; however, modern scholars, especially from the 19th century onward, place the books' authorship in the 6th and 5th centuries BC, hundreds of years after Moses is supposed to have lived.Davies (1998), p. 37 Based on scientific interpretation of archaeological, genetic, and linguistic evidence, most scholars consider Genesis to be primarily mythological rather than historical. It is divisible into two parts, the primeval history (chapters 1–11) and the anc ...

Cain Leadeth Abel To Death Tissot
Cain ''Káïn''; ar, قابيل/قايين, Qābīl/Qāyīn is a Biblical figure in the Book of Genesis within Abrahamic religions. He is the elder brother of Abel, and the firstborn son of Adam and Eve, the first couple within the Bible. He was a farmer who gave an offering of his crops to God. However, God was not pleased and favored Abel's offering over Cain's. Out of jealousy, Cain killed his brother, for which he was punished by God with the curse and mark of Cain. He had several children, starting with Enoch and including Lamech. The narrative is notably unclear on Cain's motive for murdering his brother, God's reason for rejecting Cain's sacrifice, and details on the identity of Cain's wife. Some traditional interpretations consider Cain to be the originator of evil, violence, or greed. According to Genesis, Cain was the first human born and the first murderer.

Wolves
The wolf (''Canis lupus''; : wolves), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest extant member of the family Canidae. It is also distinguished from other '' Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large prey, its more social nature, and its highly adva ...

Siblicide
Siblicide (attributed by behavioural ecologist Doug Mock to Barbara M. Braun) is the killing of an infant individual by its close relatives (full or half siblings). It may occur directly between siblings or be mediated by the parents, and is driven by the direct fitness benefits to the perpetrator and sometimes its parents. Siblicide has mainly, but not only, been observed in birds. (The word is also used as a unifying term for fratricide and sororicide in the human species; unlike these more specific terms, it leaves the sex of the victim unspecified.) Siblicidal behavior can be either obligate or facultative. Obligate siblicide is when a sibling almost always ends up being killed. Facultative siblicide means that siblicide may or may not occur, based on environmental conditions. In birds, obligate siblicidal behavior results in the older chick killing the other chick(s). In facultative siblicidal animals, fighting is frequent, but does not always lead to death of a sibling; th ...

Spotted Hyena
The spotted hyena (''Crocuta crocuta''), also known as the laughing hyena, is a hyena species, currently classed as the sole extant member of the genus ''Crocuta'', native to sub-Saharan Africa. It is listed as being of least concern by the IUCN on account of its widespread range and large numbers estimated between 27,000 and 47,000 individuals. The species is, however, experiencing declines outside of protected areas due to habitat loss and poaching. The species may have originated in Asia, and once ranged throughout Europe for at least one million years until the end of the Late Pleistocene. The spotted hyena is the largest known member of the Hyaenidae, and is further physically distinguished from other species by its vaguely bear-like build, its rounded ears, its less prominent mane, its spotted pelt, its more dual-purposed dentition, its fewer nipples and the presence of a pseudo-penis in the female. It is the only placental mammalian species where females lack an external ...

Blue-footed Booby
The blue-footed booby (''Sula nebouxii'') is a marine bird native to subtropical and tropical regions of the eastern Pacific Ocean. It is one of six species of the genus '' Sula'' – known as boobies. It is easily recognizable by its distinctive bright blue feet, which is a sexually selected trait and a product of their diet. Males display their feet in an elaborate mating ritual by lifting them up and down while strutting before the female. The female is slightly larger than the male and can measure up to long with a wingspan up to . The natural breeding habitats of the blue-footed booby are the tropical and subtropical islands of the Pacific Ocean. It can be found from the Gulf of California south along the western coasts of Central and South America to Peru. About half of all breeding pairs nest on the Galápagos Islands. Its diet mainly consists of fish, which it obtains by diving and sometimes swimming under water in search of its prey. It sometimes hunts alone, but us ...

Black Eagle
The black eagle (''Ictinaetus malaiensis'') is a bird of prey. Like all eagles, it is in the family Accipitridae, and is the only member of the genus ''Ictinaetus''. They soar over forests in the hilly regions of tropical and subtropical South and Southeast Asia, as well as southeastern China. They hunt mammals and birds, particularly at their nests. They are easily identified by their widely splayed and long primary "fingers", the characteristic silhouette, slow flight and yellow ceres and legs that contrast with their dark feathers. Taxonomy and systematics The species name is spelt ''malayensis'' in most publications but the original spelling used by Temminck in his description uses the spelling ''malaiensis'' according to a 2011 finding of some of the original covers of the part publications leading to taxonomists applying the principle of priority and rejecting any later spelling emendations.

Psychological Egoism
Psychological egoism is the view that humans are always motivated by self-interest and selfishness, even in what seem to be acts of altruism. It claims that, when people choose to help others, they do so ultimately because of the personal benefits that they themselves expect to obtain, directly or indirectly, from so doing. This is a descriptive rather than normative view, since it only makes claims about how things are, not how they “ought to be” according to some. It is, however, related to several other normative forms of egoism, such as ethical egoism and rational egoism. Subtypes of psychological egoism Psychological hedonism A specific form of psychological egoism is psychological hedonism, the view that the ultimate motive for all voluntary human action is the desire to experience pleasure or to avoid pain. Immediate gratification can be sacrificed for a chance of greater, future pleasure. Further, humans are not motivated to strictly avoid pain and only pur ...
