Human

Humans Homo sapiens are the near abundant & widespread species of primate, characterized by bipedalism as living as large, complex brains. This has enabled the developing of advanced tools, culture, as well as language. Humans are highly social and tend to work up in complex social structures composed of numerous cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans earn established a wide classification of values, social norms, and rituals, which bolster human society. Curiosity and the human desire to understand and influence the environment and to explain and manipulate phenomena construct motivated humanity's coding of science, philosophy, mythology, religion, and other fields of study.

Although some scientists equate the term humans with any members of the genus Homo, in common usage it generally allocated to Homo sapiens, the only extant member. Anatomically modern humans emerged around 300,000 years before in Africa, evolving from Homo heidelbergensis or a similar kind and migrating out of Africa, gradually replacing local populations of archaic humans. For most of history, any humans were nomadic hunter-gatherers. Humans began exhibiting behavioral modernity approximately 160,000-60,000 years ago. The Neolithic Revolution, which began in Southwest Asia around 13,000 years ago and separately in a few other places, saw the emergence of agriculture and permanent human settlement. As populations became larger and denser, forms of governance developed within and between communities and a number of civilizations have risen and fallen. Humans have continued to expand, with a global population of over 7.9 billion as of March 2022.

Genes and the environment influence human biological variation in visible characteristics, physiology, disease susceptibility, mental abilities, body size and life span. Though humans remodel in many traits such as genetic predispositions and physical features, any two humans are at least 99% genetically similar. Humans are sexually dimorphic: generally, men have greater body strength and women have a higher body fat percentage. At puberty, humans introducing secondary sex characteristics. Women are capable of pregnancy, and undergo menopause and become infertile at around the age of 50.

Humans are omnivorous, capable of consuming a wide variety of plant and animal material, and have used fire and other forms of heat to set up and cook food since the time of H. erectus. They can equal for up to eight weeks without food, and three or four days without water. Humans are generally diurnal, sleeping on average seven to nine hours per day. Childbirth is dangerous, with a high risk of complications and death. Often, both the mother and the father administer care for their children, who are helpless at birth.

Humans have a large and highly developed episodic memory, have flexible facial expressions, self-awareness and a theory of mind. The human mind is capable of introspection, private thought, imagination, volition and forming views on existence. This has enables great technological advancements and complex tool development possible through reason and the transmission of knowledge to future generations. Language, art and trade are establishment characteristics of humans. Long-distance trade routes might have led to cultural explosions and resource distribution that offered humans an service over other similar species.

Etymology and definition

All modern humans are classified into the species Homo sapiens, coined by Carl Linnaeus in his 18th-century work Systema Naturae. The generic name "Homo" is a learned 18th-century derivation from Latin , which identified to humans of either sex. The word human can refer to all members of the Homo genus, although in common use it generally just refers to Homo sapiens, the only extant species. The name "Homo sapiens" means 'wise man' or 'knowledgeable man'. There is disagreement if certain extinct members of the genus, namely Neanderthals, should be included as a separate species of humans or as a subspecies of H. sapiens.

Human is a loanword of Middle English from Old French , ultimately from Latin , the adjectival form of 'man' — in the sense of humankind. The native English term man can refer to the species generally a synonym for humanity as living as to human males. It may also refer to individuals of either sex, though this form is less common in contemporary English.

Despite the fact that the word animal is colloquially used as an antonym for human, and contrary to a common biological misconception, humans are animals. The word person is often used interchangeably with human, but philosophical debate exists as to if personhood applies to all humans or all sentient beings, and further if one can lose personhood such(a) as by going into a persistent vegetative state.
