This separation can prevent gene flow between the populations, allowing them to diverge genetically over time. If the isolation persists, the populations may evolve independently, potentially leading to the formation of new species\u2014a process known as <strong>allopatric speciation<\/strong>.<\/p>\n<p>However, <strong>option A (&#8220;It always leads to the formation of new species.&#8221;) is incorrect<\/strong> because speciation is not guaranteed. Evolutionary divergence depends on several factors, including the length of isolation, mutation rates, natural selection, and genetic drift. If the geographic barrier is removed before significant divergence occurs, the populations may resume interbreeding, preventing speciation.<\/p>\n<p style=\"text-align: center;\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-11004\" src=\"https:\/\/casestudyhelp.com\/sample-questions\/wp-content\/uploads\/2025\/06\/your-first-order.png\" alt=\"your first order\" width=\"800\" height=\"200\" srcset=\"https:\/\/casestudyhelp.com\/sample-questions\/wp-content\/uploads\/2025\/06\/your-first-order.png 800w, https:\/\/casestudyhelp.com\/sample-questions\/wp-content\/uploads\/2025\/06\/your-first-order-300x75.png 300w, https:\/\/casestudyhelp.com\/sample-questions\/wp-content\/uploads\/2025\/06\/your-first-order-768x192.png 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n<h2><strong>Looking for a Reliable MBA Assignment Helper in the UK?
