Black people is a term which is usually used to define a racial group of human beings with darker skin color, and include mostly African descent, but also any of the populations characterized by dark skin color, such as populations from Oceania and Southern Asia.
These races are distinguished from other human races based on theirs dark skin color and sometimes curly hair.
The belief a long time ago was that not only did the races differ in appearance but in behavior, intellect and origins. Today, most scholars have helped to dispel many of the earlier myths about race; discoveries made in the late twentieth century demonstrated that 99.9% of any person’s DNA is exactly the same as any other person’s, regardless of ethnicity. The 0.1% variation is the same at any two individuals within a particular population, or even at any two individuals selected from any two populations in the world. Hence, human differences are too small to qualify races as separate sub-species.
Based from genetic evidence, contemporary world population is assumed to be descended from a small population of Homo sapiens living in Africa some 70,000 years ago. The differences in physical appearance between the various peoples of the world represent the result of adaptations to the different environments.
By 1.2 million years ago, all people having descendants today had exactly the receptor protein of today's Africans; their skin was dark, and the intense sun killed off the progeny with any lighter skin. Hence when humans migrated to less sun-intensive regions in the north, low vitamin D3 levels became a problem and lighter skin colors started appearing. The people of Europe, who have low levels of melanin, naturally have an almost colorless skin pigmentation, especially when un-tanned.
Christopher Hitchens was offended by the notion of Clinton as the first black president noting "we can still define blackness by the following symptoms: alcoholic mothers, under-the-bridge habits...the tendency to sexual predation and shameless perjury about the same"
Barack Obama, described as the first black candidate with a serious chance of winning the presidency, refers to himself as black and African American using both terms interchangeably. Some have questioned whether Obama is black enough, since his mother is white American. Surveys showed that much of Obama's support is derived from white liberals; on the other hand, Hillary Clinton is more popular amongst black voters than Obama.
- From the year 1500 to 1850 an estimated 3.5 million Africans were forcibly shipped to Brazil. Thus, an estimated 80 million Brazilians, almost half the population, are at least in part descendants of these Africans;
- In 2001, the surveys showed that in Great Britain lived over one million Afro-Americans.
