But the involvement of the intelligent designers is necessary for interbreeding of tigers and lions, or the development of chihuahuas and great danes.
What about the extensive testing done on fruit flies? Doesn't that refute speciation?
Wouldn't you expect to find new species developing naturally? But what transitional forms can you point to show that this happens today? What caused the sudden appearance of new species in the Cambrian explosion?
In discussion of science and teaching our kids, shouldn't we stay within the available evidence and make it clear we are speculating concerning evolution, or ID for that matter?
Some hybrids happen naturally in the wild. Wolphins for example (cross between killer whale and dolphin).

I don't see how. There is ample evidence that speciation has occured just from looking at biogeography. For example similar speices tend to be clumped in the same region. Species on islands are similar to species on nearby mainlands. This is best explained as the island species originating from founders from the mainland species.
Besides evolution critics tend to strongly accept speciation. ID strongly accepts speciation (it accepts common descent too), and so does creationism. In fact young earth creationism requires a much faster rate of speciation than even evolutionists think is possible, because they have to explain the divergance of each kind that was on the ark in just a few thousand years. For example there are over 1000 species of bats. Young Earth Creationists would say that they all came from a few original bat species that were on the ark. That means those few original bat species had to speciate into 1000 new species starting in 4500 BC.

Speciation doesn't requre transitional forms. A red squirrel and a grey squirrel look pretty identical except their color, yet they are seperate species.

Speciation

I don't see speciation as speculation.
