Detailed explanation-1: -The correct sequence of events for evolution to occur through isolation is: founding population arrives, biogeographic isolation occurs, genetic changes occur, reproductive isolation results. Evolution is a natural phenomenon of natural selection.
Detailed explanation-2: -Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms.
Detailed explanation-3: -Answer and Explanation: Of the following options reproductive isolation must occur for speciation to happen. geographic isolation alone will not result in speciation, but geographic isolation can eventually lead to reproductive isolation which is necessary for speciation.
Detailed explanation-4: -In other words, the lack of interbreeding or reproductive isolation has to happen for the process of speciation to begin. Given enough time in which two populations are reproductively isolated, speciation happens. Geographic isolation can lead to reproductive isolation.
Detailed explanation-5: -These include genetic incompatibility, zygotic mortality, hybrid inviability, hybrid sterility, and hybrid breakdown.
