The Journey of Man: A Genetic Odyssey is a 2002 book by Spencer Wells, an American geneticist and anthropologist, in which he uses techniques and theories of genetics and evolutionary biology to trace the geographical dispersal of early human migrations out of Africa. The book was made into a TV documentary in 2003. [1]
Here are some fun map facts for you: one of the oldest surviving maps is the Babylonian Map of The World. Archaeologists date it back to around 700 to 500 B.C. The map was a clay tablet nearly the ...
Satellite view of Africa 1916 physical map of Africa. The average elevation of the continent approximates closely to 600 m (2,000 ft) above sea level, roughly near to the mean elevation of both North and South America, but considerably less than that of Asia, 950 m (3,120 ft). In contrast with other continents, it is marked by the comparatively ...
Africa's population is the youngest among all the continents; [10] [11] the median age in 2012 was 19.7, when the worldwide median age was 30.4. [12] Based on 2024 projections, Africa's population will reach 3.8 billion people by 2099. [13] Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth ...
The National Geographic Society (NGS) began using the Robinson projection for general-purpose world maps in 1988, replacing the Van der Grinten projection. [2] In 1998, NGS abandoned the Robinson projection for that use in favor of the Winkel tripel projection , as the latter "reduces the distortion of land masses as they near the poles".

A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
Archaic humans emerged out of Africa between 0.5 and 1.8 million years ago. This was followed by the emergence of modern humans ( Homo sapiens ) in East Africa around 300,000–250,000 years ago. In the 4th millennium BC written history arose in Ancient Egypt , [ 1 ] and later in Nubia 's Kush , the Horn of Africa 's Dʿmt , and Ifrikiya 's ...
