At about 30.2 million km2 (11.7 million sq mi) including adjacent islands, it covers six percent of the Earth's total surface area and 20.4 percent of the total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It has 54 fully recognized sovereign states ("countries"), nine territories and two de facto independent states with limited or no recognition. Africa's population is the youngest among all the continents; 50% of Africans are 19 years old or younger. Algeria is Africa's largest country by area, and Nigeria is the largest by population. Africa, particularly central Eastern Africa, is widely accepted as the place of origin of humans and the Hominidae clade (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 (modern human) found in Ethiopia being dated to circa 200,000 years ago. Africa straddles the equator and encompasses numerous climate areas; it is the only continent to stretch from the northern temperate to southern temperate zones. The Pygmy Hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis) is a large mammal native to the forests and swamps of western Africa (the scientific species classification means "of Liberia", as this is where the vast majority lives). The pygmy hippo is reclusive and nocturnal. It is one of only two extant species in the hippopotamidae family, the other being its much larger cousin the common hippopotamus. Pygmy hippos were unknown outside of West Africa until the 19th century. Introduced to zoos in the early 20th century, they breed well in captivity and the vast majority of research is derived from zoo specimens. The survival of the species in captivity is more assured than in the wild; the World Conservation Union estimates that there are less than 3,000 pygmy hippos remaining in the wild. Pygmy hippos are primarily threatened by loss of habitat, as forests are logged and converted to farm land, and are also vulnerable to poaching, hunting, natural predators and war. (Read more...)

Tadrart means 'mountain' in the native language of the area (Tamahaq language). The Acacus has a large variation of landscapes, from differently coloured sanddunes to arches, gorges, rocks and mountains. Major landmarks are the arches of Afzejare and Tin Khlega. Although this area is one of the most arid of the Sahara, there is vegetation, such as the callotropis plant. The area is known for its rock-art and was inscribed as a UNESCO World Heritage Site in 1985 because of the importance of these paintings and carvings. What are portals?
