The okapi is sometimes referred to as a living fossil, as it has existed as a species over a long geological time period, and morphologically resembles more primitive forms (e.g. Samotherium). [16] [23] In 2016, a genetic study found that the common ancestor of giraffe and okapi lived about 11.5 million years ago. [24]
The original drawing of the line in Wallace's paper. One of the earliest descriptions of the biodiversity in the Indo-Australian Archipelago dates back to 1521 when Venetian explorer Pigafetta recorded the biological contrasts between the Philippines and the Maluku Islands (Spice Islands) (on opposite sides of the Wallace's Line) during the continuation of the voyage of Ferdinand Magellan ...

The Giraffidae are a family of ruminant artiodactyl mammals that share a recent common ancestor with deer and bovids.This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe (between one and eight, usually four, species of Giraffa, depending on taxonomic interpretation) and the okapi (the only known species of Okapia).
The Okapi Wildlife Reserve was added to the list of World Heritage Sites in danger in 1997. The main threats to the reserve are deforestation, primarily caused by slash and burn agriculture, and commercial hunting for the sale of bushmeat. Gold mining has also been problematic to the Reserve. As of 2005, the fighting in the eastern part of the ...
In medieval T and O maps, Asia makes for half the world's landmass, with Africa and Europe accounting for a quarter each. With the High Middle Ages, Southwest and Central Asia receive better resolution in Muslim geography, and the 11th century map by Mahmud al-Kashgari is the first world map drawn from a Central Asian point of view.
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.
Kunyu Wanguo Quantu, printed in Ming China at the request of the Wanli Emperor in 1602 by the Italian Catholic missionary Matteo Ricci and Chinese collaborators, the mandarin Zhong Wentao, and the technical translator Li Zhizao, is the earliest known Chinese world map with the style of European maps.
