Abstract

Natural selection, a cornerstone of evolutionary biology, shapes the adaptations organisms develop to survive environmental pressures. This paper explores how natural selection drives biological adaptations to radiation exposure. We examine the genetic mechanisms at play, exemplified by the enhanced DNA repair capabilities observed in bacteria like Escherichia coli (E. coli) following exposure to radiation. We then investigate adaptations in humans residing in high-background radiation areas, highlighting potential genetic variations for radiation resistance. Finally, the contemporary relevance of natural selection is discussed, emphasizing its role in the emergence of antibiotic-resistant bacteria and the need for sustainable medical practices. By studying these adaptations, we gain a deeper understanding of evolution and its implications for medicine, conservation, and our overall understanding of life.

选择生存:自然选择在发展生物辐射防御中的作用。
自然选择是进化生物学的基石,它塑造了生物体在环境压力下生存的适应性。本文探讨了自然选择如何驱动生物适应辐射暴露。我们研究了起作用的遗传机制,例如在大肠杆菌(E. coli)等细菌暴露于辐射后观察到的DNA修复能力增强。然后,我们研究了居住在高本底辐射地区的人类的适应性,强调了辐射抗性的潜在遗传变异。最后,讨论了自然选择的当代相关性,强调其在抗生素耐药细菌出现中的作用和可持续医疗实践的需要。通过研究这些适应性,我们对进化有了更深的理解,对医学、自然保护和我们对生命的整体理解也有了更深的理解。
