What do all opec nations have in common

The OPEC stands for Organization of Petroleum Exporting Countries. It is formed by 15 countries. As its name says it, all of the countries which are members of this group export petroleum. As a whole, the group produces around 40% of the World's oil and accounts for around 80% of the World's oil reserves. Such control over the industry grants them a big influence when it comes to the pricing of this resource.

All the nations belonging to the OPEC (Organization of the Petroleum Exporting Countries) have in common being oil-exporting developing nations.

The mission is to coordinate and unify the petroleum policies of its Member Countries and ensure stabilization of oil markets.

It was founded in Spetember 14th, 1960 during a meeting in the Iraqui capital of Baghdad, attended by five founder members: Iran, Iraq, Kuwait, Saudi Arabia and Venezuela. These countries were later joined by Qatar, Nigeria, Congo, Indonesia, among others. Currently, the organization has a total of 15 Member Countries, ditinguished between Founders and Full Members.

early human migrations are the earliest migrations and expansions of archaic and modern humans across continents and are believed to have begun approximately 2 million years ago with the out of africa migration of homo erectus. this initial migration was followed by other archaic humans including h. heidelbergensis, which lived around 500,000 years ago and was the likely ancestor of both denisovans and neanderthals. early hominids were said to have "crossed land bridges that were eventually covered in water" .

within africa, homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago.the "recent african origin" paradigm suggests that the anatomically modern humans outside of africa descend from a population of homo sapiens migrating from east africa roughly 70,000 years ago and spreading along the southern coast of asia and to oceania before 50,000 years ago. modern humans spread across europe about 40,000 years ago.

the migrating modern human populations are known to have interbred with local varieties of archaic humans, so that contemporary human populations are descended in small part (below 10% contribution) from regional varieties of archaic humans.

after the last glacial maximum, north eurasian populations migrated to the americas about 20,000 years ago. northern eurasia was peopled after 12,000 years ago, in the beginning holocene. arctic canada and greenland were reached by the paleo-eskimo expansion around 4,000 years ago. finally, polynesia was peopled after 2,000 years ago, by the austronesian expansion.
