Detailed explanation-1: -For the example above, the finches on one island do not breed with finches from another island due to the physical barrier between them. Eventually, they will not mate due to changes in behaviors, or will not produce viable offspring due to changes in physiology.
Detailed explanation-2: -role in speciation …that prevent interbreeding are called reproductive isolating mechanisms (RIMs). Oaks on different islands, minnows in different rivers, or squirrels in different mountain ranges cannot interbreed because they are physically separated, not necessarily because they are biologically incompatible.
Detailed explanation-3: -Behavioral isolation occurs when two populations that are capable of interbreeding develop differences in courtship rituals or other behaviors.
Detailed explanation-4: -Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge.
Detailed explanation-5: -What Is Behavioral Isolation? It’s a type of reproductive isolation, meaning it prevents some members of a population from mating with others. It is also a type of pre-zygotic barrier because it happens before two organisms try to reproduce.
