It's never been my contention that gradual change in species is impossible. My contention is that the dramatic and continuing change in the make up of the earth happens one species at a time and each of these changes is usually very sudden.They asked you a question, not for a re-statement of your claims. At what point is a change in allele frequency a "fundamental shift" as opposed to merely a gradual shift? Are you unaware that changes in allele frequencies over time can happen gradually?
Only God can answer the question of when sufficient "evolution" in a given species can be considered a new species. Well, more accurately, perhaps, is that this is a semantical question or a taxonomic question and I believe in neither semantics nor taxonomies. Frankly my emphasis on individuals is simply because I don't believe any two "rabbits" are exactly the same species. Only individuals act and are conscious and counting "rabbits" can lead one astray. Each fossil represents an individual and forgetting this might lead one astray.
I would say that a species has undergone sufficient change that aggregate behavior and average appearance of adults has changed enough that they are no longer appear to be the original species. In extreme situations any major change in appearance or behavior constitutes a new species. This is why I believe we are a new species, homo omnisciencis. We once acted strictly on our knowledge like all other species and now act solely on our beliefs since our operating system changed from digital to analog. We look the same but we certainly don't act the same, individually nor collectively.
