Brian D. Harper quoted Steve Jones:
>SJ:===
>>No. I "admitted" that "change over time" occurred, but this could be
>>the result of *progressive creation*. To date you have not given
>>a "*unique*, non-circular, definition of `macro-evolution' ", let
>>alone showed that it occurred.

Note the use of the past tense in Steve's final sentence. Perhaps it comes
from Brian's definition of macro-evolution (origin of novelty) earlier.
Thus the place to look for macroevolution is in the fossil record. But it
seems to me that speciation ought to be considered macroevolution, since
it's a change that produces a new noninterbreeding population. And
speciation is happening today. It's been documented. Check the
talk.origins archives. Last time I looked there was a long list of
references to documented speciation events.
