II. Causes of Ko'p hujayrali hayvonlarni kelib chiqish
There are various theories and hypotheses regarding the causes of the emergence of multiple animal 
species in a particular area. One view suggests that topographical features of an area play a significant 
role in the process. Different types of landscapes may provide varied ecological niches, which can give 
rise to a diverse range of animals. Another hypothesis focuses on geological and climatic events that 
may lead to the separation of populations in an area, establishing different gene pools, and ultimately 
resulting in speciation. The introduction of new species by outside influences like humans, accidental 
or intentional, may also foster the emergence of diverse animal species. Anthropogenic factors such as 
habitat destruction and fragmentation, pollution, and climate change may also have an impact on the 
increasing number of animal species in a region. Therefore, the causes of ko'p hujayrali hayvonlarni kelib 
chiqish are multifaceted and complex, encompassing various natural and human-driven factors.
A. Abundance of resources
Despite the abundance of resources available in certain regions, such as the vast grasslands of Central Asia, 
the domestication and breeding of animals has not been a simple or straightforward process. In fact, it has 
required a deep understanding of the biology and behavior of various species, as well as the development 
of specific technologies and practices to support the care and management of these animals. For example, 
the development of corrals and other enclosures allowed for the controlled breeding of livestock, while 
advances in veterinary medicine and animal husbandry helped to maintain the health and productivity of 
these animals. Likewise, the grazing practices of pastoralists evolved over time, in response to changing 
ecological and environmental conditions, resulting in sophisticated systems of rotational grazing, which 
could support herds of hundreds or thousands of animals over vast areas of land. Ultimately, the abundance 
of resources in certain regions was only one factor among many that contributed to the emergence and 
success of pastoralism as a way of life.
