Figure 11.14 The only illustration in Darwin's On the Origin of Species is (a) a diagram showing speciation events leading to biological diversity. Plus, just because organisms live in different places doesn't necessarily mean that they are of different species. But why is it that different species can't successfully interbreed? Although several mechanisms have been proposed to explain how speciation occurs, allopatric, parapatric, peripatric, and sympatric speciation have been considered to be the basic modes of speciation. Many kinds of landscape features can separate populations of the same species, such as a mountain range or ocean water surrounding a chain of islands.Take, for example, the Congo River. In some cases, the chromosomal mismatch is lethal to the embryo or results in an individual that can survive but is unhealthy.
