That's the crucial difference between evolution and creation. Remine blurs this difference by his phrase 'linked by design'. Remine has the tendency to talk about 'linked' while believing in independent creation. Independent is not linked. But discontinuity is the opposite of 'linkage'.
Discontinuity means 'no linkage'.
Remine's motives could be that he wants to 'explain' universals and similarities in this way. However if one believes in independent creation one should accept the consequences of such a worldview. Directly created organisms do not inherit anything from their ancestors, because they have none. Directly created organisms do not inherit anything from their ancestors, because they have none. The fact that creationists feel the need to invoke supernatural creations points to the absence of natural links between all species in their worldview.
