We'd have to have definitions of Macro evolution and "witness".
Personally I accept that marcro evolution (at any level you care to define) has been "observed" -- not the same word as "witness".
I will take witness as meaning happening in front of ones eyes (which for some levels of marco-E is close enough to true). However observation can be done in other ways. We "observe" the after effects of something for example.
The biological definition of "macro-E" involves speciation. This has been seen to be happening right now.
There are other definitions but they would have to be defined first. I've read some creationist material on "kinds" but they seem to have trouble being very clear on what the heck that means. Every definition that I've read that is semi clear is a case where we have "observations" for it. (and some start to tread into having humans and the great apes in the same kind :-) This seems to be part of the reason that a good definition is avoided. lol ).
(I'm feeling this is getting off topic, but the topic seems to be pretty broad and we are in "Is It Science?" so I guess this is ok.
black holes are undetectable. Perhaps they do not exist. The only reason one might think they exist is that they fit a mathematical model.
The mathematics of black holes came decades before any possibility of observation existed. However, my limited understanding is that we now have observations that can only be explained by the black hole model. Is someone saying these observations can be explained in other ways?

Is there a model that macroevolution is being forced into?
Darwin did have some (not a lot compared to today of course) evidence for macroevolution before he published his theory. It is this that his model was attempting to explain.
I would say that there is no "forced" at all. If you think there is please point it out.
