Lampedusa

North Africa is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region. However, it is sometimes defined as stretching from the Atlantic shores of the Western Sahara in the west, to Egypt and Sudan's Red Sea coast in the east.

The most common definition for the region's boundaries includes Algeria, Egypt, Libya, Morocco, Tunisia, and Western Sahara, the territory disputed between Morocco and the partially recognized Sahrawi Arab Democratic Republic. The United Nations’ definition includes all these countries as well as Sudan. The African Union defines the region similarly, only differing from the UN in excluding the Sudan and including Mauritania. The Sahel, south of the Sahara Desert, can be considered as the southern boundary of North Africa. North Africa includes the Spanish cities of Ceuta and Melilla, and the plazas de soberanía. It can also be considered to include Malta, as well as other Italian, Portuguese, and Spanish regions such as Lampedusa and Lampione, Madeira, and the Canary Islands, which are all either closer to the African continent than Europe or as close to the African continent as Europe.

The Pelagie Islands (Italian: Isole Pelagie; Sicilian: Ìsuli Pilaggî), from the Greek πέλαγος, pélagos meaning "open sea", are the three small islands of Lampedusa, Lampione, and Linosa, located in the Mediterranean Sea between Malta and Tunisia, south of Sicily. To the northwest lie the island of Pantelleria and the Strait of Sicily. All three islands are part of the comune of Lampedusa e Linosa. Geologically, part of the archipelago (Lampedusa and Lampione) is on the African continental shelf, while Linosa is of volcanic origin. Politically and administratively though, the islands fall within the Sicilian province of Agrigento and represent the southernmost part of Italy.

Despite pockets of agriculture, the islands are unnaturally barren due to wanton deforestation and the disappearance of the native olive groves, juniper and carob plantations. Fifty years ago much of the landscape was farmland bounded by dry stone walls but today, the local economy is based on sponge fishing and canning, supplemented by tourism in Lampedusa.

Lampedusa e Linosa (Sicilian: Lampidusa e Linusa) is a comune (municipality) in the Province of Agrigento in the Italian region of Sicily. Located about 220 km (137 miles) southwest of Agrigento and about 260 km (162 miles) southeast of Tunis, it is the southernmost comune of Italy. It includes the isles of Lampedusa, Linosa and Lampione, collectively known as the Pelagie Islands. It has a population of 6,488.

The genetic history of North Africa encompasses the genetic history of the people of North Africa. The most important source of gene flow to North Africa from the Neolithic Era onwards was from Western Asia, while the Sahara desert to the south and the Mediterranean Sea to the north were also important barriers to gene flow from sub-Saharan Africa and parts of Europe in prehistory. However, North Africa is connected to Western Asia via the Isthmus of Suez and the Sinai peninsula, while at the Straits of Gibraltar, North Africa and Europe are separated by only 15 km (9 mi), similarly Malta, Sicily, Canary Islands, Lampedusa and Crete are close to the coasts of North Africa, with the indigenous Guanche people of the Canary Islands being Berber.

North Africa is a genetically heterogenous and diverse region, and is characterized by its diverse ethnic groups, the main ones being Arabs, Berbers and Copts (in Egypt). North African populations show a complex and heterogeneous genetic structure that has been described as an amalgam of at least four different ancestral components from the Middle East, sub-Saharan Africa, Europe and also indigenous North Africans who are genetically distinct from these three. Although North Africa has experienced gene flows from the surrounding regions, it has also experienced long periods of genetic isolation. Some genetic studies have been criticised for their interpretation and categorisation of African genetic data.
