I think it turns out just that "species" is just a human construct. It's not something hard-and-fast that nature hews to. It's nothing but a construct we use for convenience in our drive for labels.

For instance, is turquoise blue? Is it green? It's kinda both. Same with organisms and populations. The farther away (evolutionarily speaking) two populations of interbreeding organisms are, the easier it is to distinguish them into different species. The closer they are, the more things start to look like turquoise.
