Ko'p hujayrali hayvonlarni kelib chuqish nazariyalari Introduction

B. Purpose of the essay
The purpose of this essay is to examine the various theoretical frameworks that attempt to explain why 
certain animals have become extinct or are endangered and to explore potential solutions to these issues. 
By analyzing these nazariyalari, or theoretical frameworks, we can gain a deeper understanding of the 
underlying causes of these environmental crises and begin to develop effective strategies for addressing 
them. The essay will focus on the perspective of ko'p hujayrali hayvonlar, or large mammals, as they are 
often the most visible and charismatic of the world's endangered species. Ultimately, the goal of this essay 
is to raise awareness about these critical issues and encourage readers to take action to help preserve the 
world's biodiversity.
C. Thesis statement
The thesis statement of this essay argues that the theories explaining the arrival of extraterrestrial beings to 
Earth are highly speculative and based on inadequate evidence. This argument is grounded in an analysis 
of the common themes present in theories surrounding the arrival of these beings, ranging from the alleged 
conspiracy theories propagated by the UFO community to religious explanations of their appearance. By 
evaluating the evidence behind these theories, it becomes clear that the supposed arrival of extraterrestrial 
beings is likely a product of human imagination and a desire to make sense of unexplainable phenomena. 
Therefore, this essay seeks to dismantle popular beliefs surrounding the arrival of extraterrestrial beings 
and encourage critical reflection on the evidence behind extraordinary claims.
Another aspect of animal migration that scientists have been studying is the navigation system of animals 
during migration. Different animals have different mechanisms for navigating and orienting themselves 
during their long journeys. For example, some birds use Earth's magnetic field to navigate, while others 
rely on visual cues such as the position of the sun, stars, and landmarks. In addition, many animals have an 

---

innate ability to sense changes in the earth's magnetic field, which allows them to detect their location and 
direction. Understanding these complex navigation systems can help us better understand the behavior of 
animals during migration and the potential impacts of human activities on their ability to navigate.
