Along with West Asia , it has already had greater increases in hot temperature extremes than the other parts of Asia, Rainfall in Central Asia had decreased, unlike elsewhere in Asia, and

Endemism usually results in organisms with specific adaptations to one particular climate or region, and the species would likely face challenges if placed in a different environment.

Such variation commonly is at the level of subspecies , varieties or morphs , whereas some variation is too slight or inconsistent for formal recognition.

An alternative method is to define the region based on ethnicity, and in particular, areas populated by Eastern Turkic , Eastern Iranian , or Mongolian peoples.

In the 90s, arts of the region underwent some significant changes.

The caveat "in appropriate habitat" is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. The term pandemism also is in use, but not all authors are consistent in

Historically, political geography and culture have been two significant parameters widely used in scholarly definitions of Central Asia. Humboldt's definition comprised every country between 5° North and 5° South of the latitude 44.5°N. Humboldt mentions some geographic features of this region, which include

Another study shows that the Uzbeks are closely related to other Turkic peoples of Central Asia and rather distant from Iranian people. The study also analysed the maternal and paternal DNA haplogroups and shows that Turkic speaking groups are more homogenous than Iranian speaking groups. Genetic studies analyzing

The dominance of the nomads ended in the 16th century, as firearms allowed settled peoples to gain control of the region.

4125-430: The like. Such distributions might be patchy, or extended, but narrow. Factors of such a nature are taken widely for granted, so they seldom are mentioned explicitly in mentioning cosmopolitan distributions. Cosmopolitanism of a particular species or variety should not be confused with cosmopolitanism of higher taxa. For example, the family Myrmeleontidae is cosmopolitan in the sense that every continent except Antarctica
4200-474: The modern world, the orca , the blue whale , and the great white shark all have cosmopolitan distribution, extending over most of the Earth's oceans . The wasp Copidosoma floridanum is another example, as it is found around the world. Other examples include humans , cats , dogs , the western honey bee , brown rats , the foliose lichen Parmelia sulcata , and the mollusc genus Mytilus . The term can also apply to some diseases.

Genetic data shows that the different Central Asian Turkic-speaking peoples have between ~22% and ~70% East Asian ancestry (represented by "Baikal hunter-gatherer ancestry" shared with other Northeast Asians and Eastern Siberians), in contrast to Iranian-speaking Central Asians, specifically Tajiks , which display genetic continuity to Indo-Iranians of
