Question

Development of reproductive isolation among members of a continuous population in absence of geographic barrier is which speciation

Answer 1

Speciation is the changing of individuals within a population so they are no longer part of the same species. This most often occurs due to geographic isolation or reproductive isolation of individuals within the population. As the species evolve and branch off, they cannot interbreed with members of the original species any longer. There are four types of speciation that can occur based on reproductive or geographic isolation, among other reasons and environmental factors.cience, Tech, Math › Animals and N

The prefix allo- means "other". When paired with the suffix -patric, meaning "place", it becomes clear that allopatric is a type of speciation caused by geographic isolation. The individuals that are isolated are literally in an "other place". The most common mechanism for geographic isolation is an actual physical barrier that gets between members of a population. This can be something like as small as a fallen tree for small organisms or as large as being split by oceans.

Allopatric speciation does not necessarily mean the two distinct populations cannot interact or even breed at first. If the barrier causing the geographic isolation can be overcome, some members of the different populations may travel back and forth. However, a majority of the populations will stay isolated from each other and as a result, they will diverge into different species.
