Word of God states that all the races can interbreed. This means they are all the same species.
They don't go into enough detail to say for 100% sure, however, that half-breeds are "viable." So they don't say one way or another if any half-breed would be capable of having children of their own.
The idea that all the races are, in fact, the same species, or have all descended from a very recent common ancestor makes a lot of sense morphologically. Despite some minor differences, most of the races look very similar. The only major morphological difference is between miqo'te and lalafell and everyone else (the rest have the same shape, just different size and slight adjustments to their features between them). I would suggest, then, that the current miqo'te and lalafell population share a common ancestor with the rest of the "spoken," however, the common ancestor they all share is slightly further back than the most recent common ancestor shared by hyur, elezen and roegadyn.
Miqo'te and lalafell pose a problem because their morphology is not only different in major ways--the skull of a miqo'te would have to be considerably different than that of a hyur, elezen or roegadyn, and their spine and vertebrae would also have to be very different to account for the flexibility of their tails--but some of their physical features are extremely unlikely or impossible without some external influence. For that reason I would suggest that both miqo'te and lalafell were magically altered hyur or near-hyur ancestors, either intentionally or environmentally, by the presence of corrupted aether. It would not be very farfetched to imagine that the miqo'te were "genetically engineered" via the use of magic in order to create a "super hunter." I don't really know why anyone would intentionally create lalafell; perhaps their existence was an accident of magically-distorted evolution.
