A member of the species Australopithecus afarensis, which lived from 3.9 million to 2.9 million years ago, Lucy helped answer some key questions. She confirmed that upright walking evolved long before hominids began using stone tools—about 2.6 million years ago—and before their brains began to expand dramatically.

Our family tree extends back for five to seven million years to the time when our ancestors took their first two-legged steps on the path toward becoming human. Some of these species were our direct ancestors. Others were on side branches on our family tree and like ancestral ‘cousins’.

The billions of human beings living today all belong to one species: Homo sapiens. As in all species, there is variation among individual human beings, from size and shape to skin tone and eye color. But we are much more alike than we are different. The DNA of all human beings living today is 99.9% alike.

The three great human races: Negroid (left), Caucasoid (center) and Mongoloid (right).

(A) The old concept of the “five races:” African, Asian, European, Native American, and Oceanian. According to this view, variation between the races is large, and thus, the each race is a separate category. Additionally, individual races are thought to have a relatively uniform genetic identity.

The world’s largest ethnic group is Han Chinese, with Mandarin being the world’s most spoken language in terms of native speakers. The world’s population is predominantly urban and suburban, and there has been significant migration toward cities and urban centres.

The five major clans in the series are Humans, Giants, Fairies, Goddess, and Demons, all of which possess powerful abilities and magical powers.

The world population can be divided into 4 major races, namely white/Caucasian, Mongoloid/Asian, Negroid/Black, and Australoid.

American Indian or Alaska Native: A person having origins in any of the original peoples of North and South America (including Central America) and who maintains tribal affiliation or community attachment.

Population structure of human races and dog breeds. A key assumption of the race-breed analogy is that both human “races” (i.e. U.S. census groupings) and dog breeds are formed and structured in similar ways, with each representing distinct groups within each species.

In the phrase “human race,” the word essentially means “species.” Soon after “race” entered the language, one of its meanings (sometimes poetic and sometimes literal) was mankind, and it often was preceded by the adjective “human.”

Etymology. The word “race”, interpreted to mean an identifiable group of people who share a common descent, was introduced into English in about 1580, from the Old French rasse (1512), from Italian razza.

noun. (1) A group or population of humans categorized on the basis of various sets of heritable characteristics (such as color of skin, eyes, and hair). (2) A descent from a common heritage, ancestor, breed or stock.

16th century

The oldest known evidence for anatomically modern humans (as of 2017) are fossils found at Jebel Irhoud, Morocco, dated about 300,000 years old. Anatomically modern human remains of eight individuals dated 300,000 years old, making them the oldest known remains categorized as “modern” (as of 2018).

Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.

OMB requires that race data be collectd for a minimum of five groups: White, Black or African American, American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander. OMB permits the Census Bureau to also use a sixth category – Some Other Race.

White. A person having origins in any of the original peoples of Europe, the Middle East, or North Africa. It includes people who indicate their race as “White” or report entries such as Irish, German, English, Scandinavian, Scottish, Near Easterners, Iranian, Lebanese, or Polish.

We ask a question about whether a person is of Hispanic, Latino, or Spanish origin to create statistics about this ethnic group. Local, state, tribal, and federal programs use these data, and they are critical factors in the basic research behind numerous policies, particularly for civil rights.

Nationality refers to the country of citizenship. Nationality is sometimes used to mean ethnicity, although the two are technically different. People can share the same nationality but be of different ethnic groups and people who share an ethnic identity can be of different nationalities.

Race and ethnicity are used to categorize certain sections of the population. In basic terms, race describes physical traits, and ethnicity refers to cultural identification. Race may also be identified as something you inherit while ethnicity is something you learn.

In other words, race is often perceived as something that’s inherent in our biology, and therefore inherited across generations. Ethnicity, on the other hand, is typically understood as something we acquire, or self-ascribe, based on factors like where we live or the culture we share with others.

Americans are the citizens and nationals of the United States of America. Although citizens and nationals make up the majority of Americans, many dual citizens, expatriates and permanent residents could also legally claim American nationality. The United States is home to people of many ethnic origins.
