They spend about half of their lives on land and the other half in the sea. The largest living species is the emperor penguin (Aptenodytes forsteri):[6] on average, adults are about 1.1 m (3 ft 7 in) tall and weigh 35 kg (77 lb). The smallest penguin species is the little blue penguin (Eudyptula minor), also known as the fairy penguin, which stands around 30–33 cm (12–13 in) tall and weighs 1.2–1.3 kg (2.6–2.9 lb).[7] Today, larger penguins generally inhabit colder regions, and smaller penguins inhabit regions with temperate or tropical climates. Some prehistoric penguin species were enormous: as tall or heavy as an adult human. There was a great diversity of species in subantarctic regions, and at least one giant species in a region around 2,000 km south of the equator 35 mya, during the Late Eocene, a climate decidedly warmer than today.[8]

The word penguin first appears in literature at the end of the 16th century as a synonym for the great auk.[9] When European explorers discovered what are today known as penguins in the Southern Hemisphere, they noticed their similar appearance to the great auk of the Northern Hemisphere and named them after this bird, although they are not closely related.[10]
The etymology of the word penguin is still debated. The English word is not apparently of French,[11]Breton[12] or Spanish[13] origin (the latter two are attributed to the French word pingouin), but first appears in English or Dutch.[14]
An alternative etymology links the word to Latinpinguis, which means 'fat' or 'oil'.[18] Support for this etymology can be found in the alternative Germanic word for penguin, fettgans or 'fat-goose', and the related Dutch word vetgans.
Adult male penguins are sometimes called cocks, females sometimes called hens; a group of penguins on land is a waddle, and a group of penguins in the water is a raft.
Since 1871, the Latin word Pinguinus has been used in scientific classification to name the genus of the great auk (Pinguinus impennis, meaning "plump or fat without flight feathers"),[19] which became extinct in the mid-19th century.[9] As confirmed by a 2004 genetic study, the genus Pinguinus belongs in the family of the auks (Alcidae), within the order of the Charadriiformes.[20][21]
The birds currently known as penguins were discovered later and were so named by sailors because of their physical resemblance to the great auk. Despite this resemblance, however, they are not auks, and are not closely related to the great auk.[10][19] They do not belong in the genus Pinguinus, and are not classified in the same family and order as the great auk. They were classified in 1831 by Charles Lucien Bonaparte in several distinct genera within the family Spheniscidae and order Sphenisciformes.
Some recent sources[3][24] apply the phylogenetic taxon Spheniscidae to what here is referred to as Spheniscinae. Furthermore, they restrict the phylogenetic taxon Sphenisciformes to flightless taxa, and establish the phylogenetic taxon Pansphenisciformes as equivalent to the Linnean taxon Sphenisciformes,[24] i.e., including any flying basal "proto-penguins" to be discovered eventually. Given that neither the relationships of the penguin subfamilies to each other nor the placement of the penguins in the avian phylogeny is presently resolved, this is confusing, so the established Linnean system is followed here.
Although the evolutionary and biogeographic history of Sphenisciformes is well-researched, many prehistoric forms are not fully described. Some seminal articles about the evolutionary history of penguins have been published since 2005.[3][25][26][27]
The oldest known fossil penguin species is Waimanu manneringi, which lived 62 mya in New Zealand.[27] While they were not as well-adapted to aquatic life as modern penguins, Waimanu were flightless, with short wings adapted for deep diving.[27] They swam on the surface using mainly their feet, but the wings were – as opposed to most other diving birds (both living and extinct) – already adapting to underwater locomotion.[29]
Perudyptes from northern Peru was dated to 42 mya. An unnamed fossil from Argentina proves that, by the Bartonian (Middle Eocene), some 39–38 mya,[30] primitive penguins had spread to South America and were in the process of expanding into Atlantic waters.[24]
During the Late Eocene and the Early Oligocene (40–30 mya), some lineages of gigantic penguins existed. Nordenskjoeld's giant penguin was the tallest, growing nearly 1.80 meters (5.9 feet) tall. The New Zealand giant penguin was probably the heaviest, weighing 80 kilograms (180 lb) or more. Both were found on New Zealand, the former also in the Antarctic farther eastwards.
Traditionally, most extinct species of penguins, giant or small, had been placed in the paraphyleticsubfamily called Palaeeudyptinae. More recently, with new taxa being discovered and placed in the phylogeny if possible, it is becoming accepted that there were at least two major extinct lineages. One or two closely related ones occurred in Patagonia, and at least one other—which is or includes the paleeudyptines as recognized today – occurred on most Antarctic and Subantarctic coasts.
Size plasticity was significant at this initial stage of radiation: on Seymour Island, Antarctica, for example, around 10 known species of penguins ranging in size from medium to large apparently coexisted some 35 mya during the Priabonian (Late Eocene).[31] It is not known whether the palaeeudyptines constitute a monophyletic lineage, or whether gigantism was evolved independently in a restricted Palaeeudyptinae and the Anthropornithinae – whether they were considered valid, or whether there was a wide size range present in the Palaeeudyptinae as delimited (i.e., including Anthropornis nordenskjoeldi).[3] The oldest well-described giant penguin, the 5-foot (1.5 m)-tall Icadyptes salasi, existed as far north as northern Peru about 36 mya.
Gigantic penguins had disappeared by the end of the Paleogene, around 25 mya. Their decline and disappearance coincided with the spread of the Squalodontidae and other primitive, fish-eating toothed whales, which competed with them for food and were ultimately more successful.[25] A new lineage, the Paraptenodytes, which includes smaller and stout-legged forms, had already arisen in southernmost South America by that time. The early Neogene saw the emergence of another morphotype in the same area, the similarly sized but more gracile Palaeospheniscinae, as well as the radiation that gave rise to the current biodiversity of penguins.
Modern penguins constitute two undisputed clades and another two more basal genera with more ambiguous relationships.[26] To help resolve the evolution of this order, 19 high-coverage genomes that, together with two previously published genomes, encompass all extant penguin species have been sequenced.[32] The origin of the Spheniscinae lies probably in the latest Paleogene and, geographically, it must have been much the same as the general area in which the order evolved: the oceans between the Australia-New Zealand region and the Antarctic.[25] Presumably diverging from other penguins around 40 mya,[25] it seems that the Spheniscinae were for quite some time limited to their ancestral area, as the well-researched deposits of the Antarctic Peninsula and Patagonia have not yielded Paleogene fossils of the subfamily. Also, the earliest spheniscine lineages are those with the most southern distribution.
The genus Aptenodytes appears to be the basalmost divergence among living penguins.[3][33] They have bright yellow-orange neck, breast, and bill patches; incubate by placing their eggs on their feet, and when they hatch the chicks are almost naked. This genus has a distribution centred on the Antarctic coasts and barely extends to some Subantarctic islands today.
Pygoscelis contains species with a fairly simple black-and-white head pattern; their distribution is intermediate, centred on Antarctic coasts but extending somewhat northwards from there. In external morphology, these apparently still resemble the common ancestor of the Spheniscinae, as Aptenodytes'autapomorphies are, in most cases, fairly pronounced adaptations related to that genus' extreme habitat conditions. As the former genus, Pygoscelis seems to have diverged during the Bartonian,[34] but the range expansion and radiation that led to the present-day diversity probably did not occur until much later; around the Burdigalian stage of the Early Miocene, roughly 20–15 mya.[25]
The generaSpheniscus and Eudyptula contain species with a mostly Subantarctic distribution centred on South America; some, however, range quite far northwards. They all lack carotenoid colouration and the former genus has a conspicuous banded head pattern; they are unique among living penguins by nesting in burrows. This group probably radiated eastwards with the Antarctic Circumpolar Current out of the ancestral range of modern penguins throughout the Chattian (Late Oligocene), starting approximately 28 mya.[25] While the two genera separated during this time, the present-day diversity is the result of a Pliocene radiation, taking place some 4–2 mya.[25]
The Megadyptes–Eudyptes clade occurs at similar latitudes (though not as far north as the Galápagos penguin), has its highest diversity in the New Zealand region, and represents a westward dispersal. They are characterized by hairy yellow ornamental head feathers; their bills are at least partly red. These two genera diverged apparently in the Middle Miocene (Langhian, roughly 15–14 mya), although the living species of Eudyptes are the product of a later radiation, stretching from about the late Tortonian (Late Miocene, 8 mya) to the end of the Pliocene.[25]
The geographical and temporal pattern of spheniscine evolution corresponds closely to two episodes of global cooling (disambiguation) documented in the paleoclimatic record.[25] The emergence of the Subantarctic lineage at the end of the Bartonian corresponds with the onset of the slow period of cooling that eventually led to the ice ages some 35 million years later. With habitat on the Antarctic coasts declining, by the Priabonian more hospitable conditions for most penguins existed in the Subantarctic regions rather than in Antarctica itself.[35] Notably, the cold Antarctic Circumpolar Current also started as a continuous circumpolar flow only around 30 mya, on the one hand forcing the Antarctic cooling, and on the other facilitating the eastward expansion of Spheniscus to South America and eventually beyond.[25] Despite this, there is no fossil evidence to support the idea of crown radiation from the Antarctic continent in the Paleogene, although DNA study favors such a radiation.[35]
Later, an interspersed period of slight warming was ended by the Middle Miocene Climate Transition, a sharp drop in global average temperature from 14 to 12 mya, and similar abrupt cooling events followed at 8 mya and 4 mya; by the end of the Tortonian, the Antarctic ice sheet was already much like today in volume and extent. The emergence of most of today's Subantarctic penguin species almost certainly was caused by this sequence of Neogene climate shifts.
Penguin ancestry beyond Waimanu remains unknown and not well-resolved by molecular or morphological analyses. The latter tend to be confounded by the strong adaptive autapomorphies of the Sphenisciformes; a sometimes perceived fairly close relationship between penguins and grebes is almost certainly an error based on both groups' strong diving adaptations, which are homoplasies. On the other hand, different DNA sequence datasets do not agree in detail with each other either.

What seems clear is that penguins belong to a clade of Neoaves (living birds except for paleognaths and fowl) that comprises what is sometimes called "higher waterbirds" to distinguish them from the more ancient waterfowl. This group contains such birds as storks, rails, and the seabirds, with the possible exception of the Charadriiformes.[36]
Inside this group, penguin relationships are far less clear. Depending on the analysis and dataset, a close relationship to Ciconiiformes[27] or to Procellariiformes[25] has been suggested. Some think the penguin-like plotopterids (usually considered relatives of cormorants and anhingas) may actually be a sister group of the penguins and those penguins may have ultimately shared a common ancestor with the Pelecaniformes and consequently would have to be included in that order, or that the plotopterids were not as close to other pelecaniforms as generally assumed, which would necessitate splitting the traditional Pelecaniformes into three.[37]
A 2014 analysis of whole genomes of 48 representative bird species has concluded that penguins are the sister group of Procellariiformes,[38] from which they diverged about 60 million years ago (95% CI, 56.8-62.7).[39]
The distantly related Puffins, which live in the North Pacific and North Atlantic, developed similar characteristics to survive in the Arctic and sub-Arctic environments. Like the penguins, puffins have a white chest, black back and short stubby wings providing excellent swimming ability in icy water. But, unlike penguins, puffins can fly, as flightless birds would not survive alongside land-based predators such as polar bears and foxes; there are no such predators in the Antarctic. Their similarities indicate that similar environments, although at great distances, can result in similar evolutionary developments, i.e. convergent evolution.[40]
Penguin wings have the same general bone structure as flighted birds, but the bones are shorter and stouter to allow them to serve as fins. 1). Humerus 2). Sesamoid Bone 3). Radius 4). Ulna 5). Radial Carpal bone 6). Carpometacarpus 7). Phalanges

A vice is a practice, behaviour, or habit generally considered morally wrong in the associated society. In more minor usage, vice can refer to a fault, a negative character trait, a defect, an infirmity, or a bad or unhealthy habit.[citation needed] Vices are usually associated with a fault in a person's character or temperament rather than their morality.[1]
Synonyms for vice include fault, sin, depravity, iniquity, wickedness, and corruption. The antonym of vice is virtue.[2]
The modern English term that best captures its original meaning is the word vicious, which means "full of vice". In this sense, the word vice comes from the Latin word vitium, meaning "failing or defect".[3][4]
Depending on the country or jurisdiction, vice crimes may or may not be treated as a separate category in the criminal codes. Even in jurisdictions where vice is not explicitly delineated in the legal code, the term vice is often used in law enforcement and judicial systems as an umbrella term for crimes involving activities that are considered inherently immoral, regardless of the legality or objective harm involved.
In the United Kingdom, the term vice is commonly used in law and law enforcement to refer to criminal offences related to prostitution and pornography.[5] In the United States, the term is also used to refer to crimes related to drugs, alcohol, and gambling.[6]
A vice squad, also called a vice unit or a morality squad, is generally, though not always, a police division, whose focus is to restrain or suppress moral crimes. Though what is considered or accepted as a moral crime by society often varies considerably according to local laws or customs between nations, countries, or states, it often includes activities such as gambling, narcotics, pornography, and illegal sales of alcoholic beverages.[7][8] Vice squads do not concentrate on more serious crimes like fraud and murder.
In the Sarvastivadin tradition of Buddhism, there are 108 defilements, or vices, which are prohibited. These are subdivided into 10 bonds and 98 proclivities.[9] The 10 bonds are the following:[9]
Christians believe there are two kinds of vice:[citation needed]
Vices that come from the physical organism as instincts, which can become perverse (such as lust)
Vices that come from false idolatry in the spiritual realm
The first kind of vice, though sinful, is believed less serious than the second. Vices recognized as spiritual by Christians include blasphemy (holiness betrayed), apostasy (faith betrayed), despair (hope betrayed), hatred (love betrayed), and indifference (scripturally, a "hardened heart"). Christian theologians have reasoned that the most destructive vice equates to a certain type of pride or the complete idolatry of the self. It is argued that through this vice, which is essentially competitive, all the worst evils come into being. In Christian theology, it originally led to the Fall of Man, and, as a purely diabolical spiritual vice, it outweighs anything else often condemned by the Church.
The Roman Catholic Church distinguishes between vice, which is a habit of sin, and the sin itself, which is an individual morally wrong act. In Roman Catholicism, the word "sin" also refers to the state that befalls one upon committing a morally wrong act. In this section, the word always means the sinful act. It is the sin, and not the vice, that deprives one of God's sanctifying grace and renders one deserving of God's punishment. Thomas Aquinas taught that "absolutely speaking, the sin surpasses the vice in wickedness".[10] On the other hand, even after a person's sins have been forgiven, the underlying habit (the vice) may remain. Just as vice was created in the first place by repeatedly yielding to the temptation to sin, so vice may be removed only by repeatedly resisting temptation and performing virtuous acts; the more entrenched the vice, the more time and effort needed to remove it. Saint Thomas Aquinas says that following rehabilitation and the acquisition of virtues, the vice does not persist as a habit, but rather as a mere disposition, and one that is in the process of being eliminated. Medieval illuminated manuscripts circulated with colorful schemas for developing proper attitudes, with scriptural allusions modelled on nature: the tree of virtues as blossoming flowers or vices bearing sterile fruit, The Renaissance writer Pietro Bembo is credited with reaffirming and promoting the Christian perfection of classical humanism. Deriving all from love (or the lack thereof) his[11] schemas were added as supplements[12] in the newly invented technology of printing by Aldus Manutius in his editions of Dante's Divine Comedy dating from early in the 16th century.
The poet Dante Alighieri listed the following seven deadly vices, associating them structurally[13] as flaws in the soul's inherent capacity for goodness as made in the Divine Image yet perverted by the Fall:
Pride or vanity: an excessive love of the self (holding the self outside of its proper position regarding God or fellows; Dante's definition was "love of self perverted to hatred and contempt for one's neighbour"). In the Latin lists of the Seven Deadly Sins, pride is referred to as superbia.
Envy or jealousy: resentment of others for their possessions (Dante: "love of one's own good perverted to a desire to deprive other men of theirs"). In the Latin lists of the Seven Deadly Sins, envy is referred to as invidia.
Wrath or anger: feelings of hatred, revenge or denial, as well as punitive desires outside of justice (Dante's description was "love of justice perverted to revenge and spite"). In the Latin lists of the Seven Deadly Sins, wrath is referred to as ira, which primitive vices tempt astray by increasingly perverting the proper purpose of charity, directing it inwards, leading to a disordered navel-gazing preoccupation with personal goods in isolation absent proper harmonious relations leading to violent disruption of balance with others.
Sloth or laziness: idleness and wastefulness of time or other allotted resources. Laziness is condemned because it results in others having to work harder; also, useful work will not be done. Sloth is referred to in Latin as accidie or acedia, which vice tempts a self-aware soul to be too easily satisfied, thwarting charity's purpose as insufficiently perceptible within the soul itself or abjectly indifferent in relationship with the needs of others and their satisfaction, an escalation in evil, more odious than the passion of hate
Avarice (covetousness, greed): a desire to possess more than one has need or use for (or according to Dante, "excessive love of money and power"). In the Latin lists of the Seven Deadly Sins, avarice is referred to as avaritia.
Gluttony: overindulgence in food, drink or intoxicants, or misplaced desire of food as a pleasure for its sensuality ("excessive love of pleasure" was Dante's rendering). In the Latin lists of the Seven Deadly Sins, gluttony is referred to as gula.
Lust: excessive sexual desire. Dante's criterion was that "lust detracts from true love". In the Latin lists of the Seven Deadly Sins, lust is referred to as luxuria, which vices tempt cultivated souls in their ability to direct charity's proper purpose to good things or actions, by indulging excess. Thus in Dante's estimation the soul's detachment from sensual appetites become the vices most difficult to tame, urges not as easily curbed by mere good manners since inflamed via appropriate use rather than inappropriate misuse. Hence conventional respect for the ninth and tenth commandments against coveting and social customs that encourage custody of the eyes and ears become prudent adjuncts to training against vice.
The first three terraces of purgatory expiate the sins which can be considered to arise from love perverted, that is, sins which arise from the heart of the sinner being set upon something which is wrong in the eyes of God. Those being purged here must have their love set upon the right path. The fourth terrace of purgatory expiates the sins which can be considered to arise from love defective, that is, love which, although directed towards the correct subjects is too weak to drive the sinner to act as they should. Those being purged here must have their love strengthened so as to drive them correctly. The fifth, sixth, and seventh terraces of purgatory expiate the sins which can be considered to arise from love excessive, that is, love which although directed towards ends which God considers good is directed towards them too much for the sinner to gain bliss from them, and also so that the sinner is distracted from the love of other things of which God approves. Their love must be cooled to a more sensible level.
Although not strictly a religion but a Hellenistic philosophy, Epicurean ethics prescribes a therapeutic approach to the vices with the goal of attaining a life of pleasure with the aid of the virtues. Most of the techniques used in Epicureanism involve challenging false beliefs and attaining beliefs that are aligned with nature. In this, Epicureanism posits an entirely naturalistic, non-religious theory of virtue and vice based on the rational pursuit of pleasure.[15]

Simplicity is the state or quality of being simple. Something easy to understand or explain seems simple, in contrast to something complicated. Alternatively, as Herbert A. Simon suggests, something is simple or complex depending on the way we choose to describe it.[1] In some uses, the label "simplicity" can imply beauty, purity, or clarity. In other cases, the term may suggest a lack of nuance or complexity relative to what is required.
The concept of simplicity is related to the field of epistemology and philosophy of science (e.g., in Occam's razor). Religions also reflect on simplicity with concepts such as divine simplicity. In human lifestyles, simplicity can denote freedom from excessive possessions or distractions, such as having a simple living style. In some cases, the term may have negative connotations, as when referring to someone as a simpleton.
There is a widespread philosophical presumption that simplicity is a theoretical virtue. This presumption that simpler theories are preferable appears in many guises. Often it remains implicit; sometimes it is invoked as a primitive, self-evident proposition; other times it is elevated to the status of a ‘Principle’ and labeled as such (for example, the 'Principle of Parsimony'.[2]
According to Occam's razor, all other things being equal, the simplest theory is most likely true. In other words, simplicity is a meta-scientific criterion by which scientists evaluate competing theories.
A distinction is often made by many persons [by whom?] between two senses of simplicity: syntactic simplicity (the number and complexity of hypotheses), and ontological simplicity (the number and complexity of things postulated). These two aspects of simplicity are often referred to as elegance and parsimony respectively.[3]
John von Neumann defines simplicity as an important esthetic criterion of scientific models:
[...] (scientific model) must satisfy certain esthetic criteria - that is, in relation to how much it describes, it must be rather simple. I think it is worth while insisting on these vague terms - for instance, on the use of word rather. One cannot tell exactly how "simple" simple is. [...] Simplicity is largely a matter of historical background, of previous conditioning, of antecedents, of customary procedures, and it is very much a function of what is explained by it.[4]
The recognition that too much complexity can have a negative effect on business performance was highlighted in research undertaken in 2011 by Simon Collinson of the Warwick Business School and the Simplicity Partnership, which found that managers who are orientated towards finding ways of making business "simpler and more straightforward" can have a beneficial impact on their organisation.
Most organizations contain some amount of complexity that is not performance enhancing, but drains value out of the company. Collinson concluded that this type of 'bad complexity' reduced profitability (EBITDA) by more than 10%.[5]
Collinson identified a role for "simplicity-minded managers", managers who were "predisposed towards simplicity", and identified a set of characteristics related to the role, namely "ruthless prioritisation", the ability to say "no", willingness to iterate, to reduce communication to the essential points of a message and the ability to engage a team.[5] His report, the Global Simplicity Index 2011, was the first ever study to calculate the cost of complexity in the world's largest organisations.[6]
The Global Simplicity Index identified that complexity occurs in five key areas of an organisation: people, processes, organisational design, strategy, and products and services.[7] As the "global brands report", the research is repeated and published annually.[8]: 3 The 2022 report incorporates a "brand simplicity score" and an "industry simplicity score".[9]
Research by Ioannis Evmoiridis at Tilburg University found that earnings reported by "high simplicity firms" are higher than among other businesses, and that such firms "exhibit[ed] a superior performance during the period 2010 - 2015", whilst requiring lower average capital expenditure and lower leverage.[8]: 18
