A continent is one of several large landmasses on Earth. They are generally identified by convention rather than any strict criteria, with seven regions commonly regarded as continents – they are (from largest in size to smallest): Asia, Africa, North America, South America, Antarctica, Europe, and Australia.^[1]

Africa is the world’s second-largest and second most-populous  content after Asia .At about 30.2 million km² (11.7 million sq mi) including adjacent islands, it covers 6% of the Earth’s total surface area and 20.4% of the total land area.^[2] With about 922 million people (as of 2005)^[3] in 61 territories, it accounts for about 14.2% of the world’s human population.The continent is surrounded by the Mediterranean Sea to the north, the Suez Canal and the Red Sea to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. There are 53 countries, including Madagascar and various island groups, associated with the continent

Africa, particularly central eastern Africa, is widely regarded within the scientific community to be the origin of humans and the Hominidae tree (great apes), as evidenced by the discovery of the earliest hominids and their ancestors, as well as later ones that have been dated to around seven million years ago – including Sahelanthropus tchadensis, Australopithecus africanus, A. afarensis, Homo erectus, H. habilis and H. ergaster – with the earliest Homo sapiens (human) found in Ethiopia being dated to ca. 200,000 years ago.
