Humans are the most abundant and widespread species of primate characterized by bipedalism and large, complex brains. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of cooperating and competing groups from families to political states. Social interactions between humans have established values, social norms, and rituals that bolster human society. Curiosity and the desire to understand and influence the environment have motivated humanity's development of science, philosophy, and other fields of study.

1. Human Being
Humans (Homo sapiens) are the most abundant and widespread species of primate, characterized
by bipedalism and large, complex brains. This has enabled the development of advanced tools, culture,
and language. Humans are highly social and tend to live in complex social structures composed of many cooperating
and competing groups, from families and kinship networks to political states. Social interactions between humans
have established a wide variety 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 have
motivated humanity's development of science, philosophy, mythology, religion, and other fields of study.

3. • Although some scientists equate the term humans with all members of the
genus Homo, in common usage it generally refers to Homo sapiens, the
only extant member. Anatomically modern humans emerged around
300,000 years ago in Africa, evolving from Homo heidelbergensis or a
similar species and migrating out of Africa, gradually replacing local
populations of archaic humans. For most of history, all humans
were nomadic hunter-gatherers. Humans began exhibiting behavioral
modernity about 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 2022.
