Answer:
The theory of E.O. Wilson's theory of Island Biogeography was originally developed as island biogeography, to explain species richness of actual islands, surrounded by water.
It proposes that the number of species found in an undisturbed environment is determined by immigration and emigration. According to him, the species richness will be the same if this island will have an equal number of the immigration and extinction or emigration of species.
That fact can be explained by the similarity in their genes.
Dogs and coyotes are from the same class, family and genus (Mammalia, Canidae, Canis).
This is almost enough for their offspring to be viable. But if the DNA is similar (which it is) offspring the chances of viable and fertile offspring is high almost at 100%.
Hope it helped,
