Chapter 47. The separation of the original population from an island into two or more groups and the operation of natural selection within an individual group are called allopatric speciation on islands. The cause of their initial separation is not clear, but it may have been caused by the glaciers of the ice age dividing an initial population into two. However, the Northern Spotted Owl and Northern Barred Owl are much more similar in mass. Furthermore, scientists have discovered that the greater the distance between two groups that were once the same species, the greater the probability that specialization occurs.
