Humans are bipedal Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs, or legs. An animal or machine that usually moves in a bipedal manner is known as a biped , meaning "two feet" (from the Latin bi for "two" and ped for "foot"). Types of bipedal movement include walking, running, or primates A primate is a member of the biological order Primates (/prаɪˈmeɪtiːz/ prī·mā′·tēz; Latin: "prime, first rank"), the group that contains lemurs, lorisids, galagos, tarsiers, monkeys, and apes (including great apes such as humans). With the exception of humans, who inhabit every continent on Earth,[a] most primates live in belonging to the species Homo sapiens (Latin Latin is an Italic language originally spoken in Latium and Ancient Rome. With the Roman conquest, Latin was spread to countries around the Mediterranean, including a large part of Europe. Romance languages, such as Aragonese, Corsican, Catalan, French, Italian, Portuguese, Romanian, and Spanish, are descended from Latin, while many others,: "wise man" or "knowing man") in Hominidae The Hominidae form a taxonomic family, including four extant genera: chimpanzees, gorillas, humans and orangutans, the great ape A number of known extinct genera are grouped with humans in the Hominina subtribe, others with orangutans in the Ponginae subtribe. The most recent common ancestor of the Hominidae lived some 13 million years ago, when the ancestors of the orangutans speciated from the ancestors of the other three genera.[citation needed] The ancestors of the family.[2][3] They are the only surviving members of the genus Homo Homo is the genus that includes modern humans and species closely related to them. The genus is estimated to be about 2.5 million years old,[citation needed] evolving from Australopithecine ancestors with the appearance of Homo habilis. The advent of Homo coincides with the first evidence of stone tools , and thus by definition with the beginning. Humans have a highly developed Encephalization is defined as the amount of brain mass exceeding that related to an animal's total body mass. Quantifying an animal's encephalization has been argued to be directly related to that animal's level of intelligence. In fact, as early as 1871, Charles Darwin wrote in his book The Descent of Man: "No one, I presume, doubts that the brain The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size. Most of the expansion comes from the cerebral cortex, a convoluted layer, capable of abstract reasoning Reasoning is the cognitive process of looking for reasons, beliefs, conclusions, actions or feelings, language A language is a particular kind of system for encoding and decoding information. Since language and languages became an object of study by the ancient grammarians, the term has had many definitions. The English word derives from Latin lingua, "language, tongue," with a reconstructed Proto-Indo-European root of *dnghû-, "tongue,&, introspection Introspection is the self-observation and reporting of conscious inner thoughts, desires and sensations. It is a conscious mental and usually purposive process relying on thinking, reasoning, and examining one's own thoughts, feelings, and, in more spiritual cases, one's soul. It can also be called contemplation of one's self, and is contrasted, and problem solving Problem solving is a mental process and is part of the larger problem process that includes problem finding and problem shaping. Considered the most complex of all intellectual functions, problem solving has been defined as higher-order cognitive process that requires the modulation and control of more routine or fundamental skills. Problem. This mental capability, combined with an erect body carriage that frees the arms for manipulating objects, has allowed humans to make far greater use of tools A tool, broadly defined, is an entity that interfaces between two or more domains; that facilitates more effective action of one domain upon the other. Basic tools are simple machines. For example, a crowbar simply functions as a lever. The further out from the pivot point, the more force is transmitted along the lever. A hammer typically than any other species. Mitochondrial DNA Mitochondrial DNA is the DNA located in organelles called mitochondria, structures within cells that convert the energy from food into a form that cells can use. Most other DNA present in eukaryotic organisms is found in the cell nucleus and fossil evidence indicates that modern humans Anatomically modern human or early modern human in paleoanthropology refers to early individuals of Homo sapiens with an appearance similar to that of modern humans. Anatomically modern humans evolved from archaic Homo sapiens in the Middle Paleolithic, about 200,000 years ago. The emergence of anatomically modern human marks the dawn of the originated in Africa Africa is the world's second-largest and second most-populous continent, after Asia. At about 30.2 million km² including adjacent islands, it covers 6% of the Earth's total surface area and 20.4% of the total land area. With a billion people (as of 2009, see table) in 61 territories, it accounts for about 14.72% of the World's human population about 200,000 years ago.[4] Humans are widespread in every continent except Antarctica Antarctica (pronounced /ænˈtɑrktɪkə/ ) is Earth's southernmost continent, underlying the South Pole. It is situated in the Antarctic region of the southern hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14.0 million km2 (5.4 million sq mi), it is the fifth-largest continent in area after, with a total population The world population is the total number of living humans on Earth at a given time. As of 7 February 2010, the Earth's population is estimated by the United States Census Bureau to be 6,801,200,000. The United Nations estimated the world's population to be 6,800,000,000 in 2009. The world population has been growing continuously since the end of of 6.8 billion as of November 2009.[5]
Like most higher primates The simians are the "higher primates" familiar to most people: the Old World monkeys and apes, including humans, (together being the catarrhines), and the New World monkeys or platyrrhines. Simians tend to be larger than the "lower primates" or prosimians, humans are social by nature. However, humans are uniquely adept at utilizing systems of communication for self-expression, the exchange of ideas, and organization. Humans create complex social structures Social structure is a term used in sociology and the other social sciences to refer to relationships or bonds between groups of individuals . Whereas 'structure' refers to "the macro", "agency" refers to "the micro". (See also: Structure and agency) composed of many cooperating and competing groups, from families Family denotes a group of people or animals affiliated by consanguinity, affinity or co-residence. Although the concept of consanguinity originally referred to relations by "blood", anthropologists[who?] have argued that one must understand the idea of "blood" metaphorically and that many societies understand family through to nations A nation is a territory or country as political entity or a grouping of people who share real or imagined common history, culture, language or ethnic origin, often possessing or seeking its own government. The development and conceptualization of a nation is closely related to the development of modern industrial states and nationalist movements. Social interactions In social science, a social relation or social interaction refers to a relationship between two , three (i.e. a triad) or more individuals (e.g. a social group). Social relations, derived from individual agency, form the basis of the social structure. To this extent social relations are always the basic object of analysis for social scientists between humans have established an extremely wide variety of values, social norms Social norms are the behavioral expectations and cues within a society or group. This sociological term has been defined as "the rules that a group uses for appropriate and inappropriate values, beliefs, attitudes and behaviors. These rules may be explicit or implicit. Failure to follow the rules can result in severe punishments, including, and rituals, which together form the basis of human society. Humans have a marked appreciation for beauty and aesthetics which, combined with the human desire for self-expression, has led to cultural innovations such as art, literature and music.
Humans are noted for their desire to understand and influence their environment, seeking to explain and manipulate natural phenomena through science, philosophy, mythology and religion. This natural curiosity has led to the development of advanced tools and skills, which are passed down culturally Culture is a term that has different meanings. For example, in 1952, Alfred Kroeber and Clyde Kluckhohn compiled a list of 164 definitions of "culture" in Culture: A Critical Review of Concepts and Definitions. However, the word "culture" is most commonly used in three basic senses:; humans are the only species known to build fires Fire is the rapid oxidation of a material in the chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not considered to be part of this definition, cook their food Cooking is the process of preparing food by applying heat. Cooks select and combine ingredients using a wide range of tools and methods. In the process, the flavor, texture, appearance, and chemical properties of the ingredients can change. Cooking techniques and ingredients vary widely across the world, reflecting unique environmental, economic,, clothe The primary purpose of clothing is functional, as a protection from the elements. Clothes also enhance safety during hazardous activities such as hiking and cooking, by providing a barrier between the skin and the environment. Clothes also provide a hygienic barrier, keeping toxins away from the body and limiting the transmission of germs themselves, and use numerous other technologies Technology deals with human as well as other animal species' usage and knowledge of tools and crafts, and how it affects a species' ability to control and adapt to its natural environment. The word technology comes from the Greek technología — téchnē (τέχνη), 'craft' and -logía (-λογία), the study of something, or the branch of.

Q. Which makes human body more heat. Any tips to keep the human body temperature optimum.
Asked by Sebastian Alex - Sat Jul 11 22:07:21 2009 - - 1 Answers - 0 Comments
A. If outside temperature is lower, best way to keep optimum temperature is to cover as much exposed skin surface as possible, and to intake more calories. Calories are what we need for energy, and some of the energy we get from calories goes into heating the body, since a majority of our body's composition is water. if outside temperature hotter, expose more skin surface area, as it will increase the surface area that can help to dissipate heat. body regulates it's own temperature in cold by lessening blood flow to extremeties like the limbs so less body heat is lost to the outside environment. most of the blood would be isolated at the core of the body, basically the trunk, and some to the head. when it's hot, the opposite happens as more… [cont.]
