If the donkey, the horse, and the zebra can produce cross-species offspring (although infertile), doesn't that imply that God didn't blink them into existence as separate species?
If he did blink them into existence as separate species in three distinct acts of creation, why would they have any chance at all of producing any sort of cross-species offspring, any more than, say, a flounder and a cottontail rabbit can?
If he didn't blink the donkey, the horse, and the zebra into existence as three separate species in three distinct acts of creation, then you must confess that they were at one time a single species. If so, how did they become three distinct species? By what process? Whatever your answer is, it cannot be that it was an example of micro evolution. It would have to be macro by definition, since they cannot produce fertile offspring cross-species, establishing that they are three different species of equine.
https://en.wikipedia.org/wiki/Equidae Equidae (sometimes known as the horse family) is the taxonomic family of horses and related animals, including the extant horses, donkeys, and zebras, and many other species known only from fossils. All extant species are in the genus Equus.
This is another example of micro evolution because the evolution is always limited to the same family of species.
