The Palearctic

The Palearctic region , also called Palearctic , describes in biogeography an old-world zoogeographic region that traditionally includes Europe , North Africa and Asia (excluding front and rear India and the southern part of the Arabian Peninsula ) as well as the islands in front of these areas. The name "Palearctic" region is derived from the Old World , in contrast to the Nearctic in the New World .


The Palearctic region emerged from the Paleogene (the older section of the Tertiary Period ) through the increasing isolation of North America from Eurasia as a result of the opening of the North Atlantic.

The Palearctic, together with the Nearctic (mainly North America), forms the Holarctic , which covers most of the land area of ​​the northern hemisphere. The allocation of individual regions is inconsistent. For example, Greenland and the Canadian Arctic Archipelago are traditionally assigned to the Nearctic, whereas in more recent classifications they are assigned to the Palearctic or a separate Arctic region limited to the highest northern latitudes. The same applies to the south of the Arabian Peninsula, which is traditionally attributed to the Afrotropic ("Ethiopian Region"), but in more recent formations a Saharo-Arab region, which is either incorporated as a sub-region in the Palearctic or an independent region.
