Neither of these is true.

Hmm, How come?

Transitional species say nothing about the mechanism that caused the
transitions. If, as very, very rarely happens, you see a smooth
transitional series between two morphologies (and have managed to
convince yourself that it's a true evolutionary transition and not any
of the various phenomena that can mimic one), then you have shown that
the transition was gradual, and so have ruled out macromutaion in that
one exceedingly rare case. But you can't have any real idea of whether
natural selection was responsible for the change or not.

Gaps may leave open the theoretical possibility of macromutation, but
unless we understand nothing about how evolution works they aren't a
viable mechanism of change.

Essentially, you are asking the fossil record to tell us more than it's
capable of.

I looked it up and posted a good article that agreed with you.
Macro mutation would seem to be more detrimental than not.
I don't think he reads the links.
