Human evolution is the process of change and development, or evolution, by which human beings emerged as a distinct species. It is the subject of a broad scientific inquiry that seeks to understand and describe how this change and development occurred. The study of human evolution encompasses many scientific disciplines, most notably physical anthropology and genetics. The term 'human', in the context of human evolution, refers to the genus Homo, but studies of human evolution usually include other hominids, such as the austral ...

The modern field of paleoanthropology began with the discovery of 'Neanderthal man'; and evidence of other 'cave men' in the 19th century. The idea that humans are similar to certain great apes had been obvious to people for some time, but the idea of the biological evolution of species in general was not legitimized until after Charles Darwin published On the Origin of Species in 1859. Though Darwin's first book on evolution did not address the specific question of human evolution— "light will be thrown on the origin of man and his ...

Humans or human beings define themselves in biological, social, and spiritual terms. Biologically, humans are classified as the mammalian species Homo sapiens (Latin for "wise man" or "thinking man"): a bipedal primate of the superfamily Hominoidea, together with the other apes: chimpanzees, gorillas, orangutans, and gibbons. Humans have an erect body carriage that frees their upper limbs for manipulating objects and a highly developed brain capable of abstract reasoning, speech, language, and ...

They go by many names, such as Star Kids, Indigos or Crystalline Children. Whatever they're called, believers say this group of prodigies started appearing about 30 years ago and may now make up as much as 90 percent of the population under ten. They also exhibit strange side effects, like a higher resistance to pollutants but an increased sensitivity to sugar and food additives. These are babies born with an inherent knowledge of art, language and spirituality, possessing an impressive wealth of wisdom. Some will even go so far as to say these kids are not only prime candidates for the gifted and talented program, but the next step in human evolution.

Neophocaena Phocoena - Harbor porpoises Phocoenoides - Dall's Porpoises The porpoises are small cetaceans of the family Phocoenidae; they are related to whales and dolphins. They are however distinct from dolphins, although the word "porpoise" is often used to refer to any small dolphin, especially in North America. A key difference is the shape of the teeth and of the head. Porpoises, divided into six species, live in all oceans, mostly near the shore. Probably best known is the H ...

Instinct is the inherent disposition of a living organism toward a particular action. Instincts are generally inherited patterns of responses or reactions to certain kinds of stimuli. In humans they are most easily observed in behaviors such as emotions, sexual drive, and other bodily functions, as these are largely biologically determined. Instinct provides a response to external stimuli, which moves an organism to action, unless overriden by intelligence, which is creative and hence far more versatile. Since instincts take generatio ...

Hematophagy is the habit of certain animals of feeding on blood (from the Greek words, haima, blood, and phagein, eat). Since blood is a fluid tissue rich in nutritious proteins and lipids and can be taken without enormous effort, hematophagy has evolved as a preferred form of feeding in many small animals, such as worms and arthropods. Some intestinal helminth worms, such as the Ascaris, feed on blood extracted from the capillaries of the gut and about 75% of all species of leeches (Hirudo medicinalis), a free-li ...

A biped (BY-ped) meaning "two feet" (Latin bi = two + ped = foot) is an animal that travels across surfaces supported by two legs. Biped - Bipedalism in general. Bipedal locomotion is walking, running, and standing on two legs. Energy-efficient means of standing bipedally involve constant adjustment of balance, and of course these must avoid overcorrection. Efficient walking complicates these issues, as it entails tipping slightly off-balance forward and to the side, and correcting bala ...

Insects are invertebrate animals of the Class Insecta, the largest and (on land) most widely distributed taxon within the Phylum Arthropoda. Insects comprise the most diverse group of animals on the earth, with over 800,000 species described—more than all other animal groups combined: "Indeed, in no one of her works has Nature more fully displayed her exhaustless ingenuity," Pliny exclaimed. Insects may be found in nearly all environments on the planet, although only a small number of species have adapted to life in the ocean ...

The origins of humanity have often been a subject of great political and religious controversy (see Creation-evolution controversy and Hybrid-origin) The classification of humans and their relatives has changed considerably over time (see History of hominoid taxonomy).

Life expectancy is also called average life span or mean life span, in particular distinction to maximum life span (the life span of the most long lived members of a class of living beings).

Animal communication is any behaviour on the part of one animal that has an effect on the current or future behaviour of another animal. The study of animal communication, called zoosemiotics (distinguishable from anthroposemiotics, the study of human communication) has played an important part in the development of ethology, sociobiology, and the study of animal cognition.

Comparative genomics studies of mammalian genomes suggest that approximately 5% of the human genome has been conserved by evolution since the divergence of those species approximately 200 million years ago, containing the vast majority of genes and regulatory sequences. Intriguingly, since genes and known regulatory sequences probably comprise less than 2% of the genome, this suggests that there may be more unknown functional sequence than known functional sequence. A smaller, but large, fraction of human genes seem ...

The average human brood size is currently one. That is to say that each birth usually produces one baby. The worldwide trend towards mothers having fewer maternities means that those that give birth to twins or even triplets may have more children in total than those who have singleton births. Medical technology now means that whilst twin and triplet maternities are usually much shorter and the babies much smaller, they now usually produce more viable children than singleton births. It has been postulated that this ...

In modern taxonomy, Homo sapiens is the only extant species of its genus, Homo. Likewise, the ongoing study of the origins of Homo sapiens often demonstrates that there were other Homo species, all of which are now extinct. While some of these other species might have been ancestors of H. sapiens, many were likely our 'cousins', having speciated away from our ancestral line. There is not yet a consensus as to which of these groups should count as separate species and which as subspecies of another species. ...
