Arrgh. A long post lost. Probably happier for readers, anyway. ];-)
Briefly: Birds didn't hatch from lizard eggs; the transitionn took place over millions of years, and there's no way to draw a bright line and say this is bird, that is reptile. In a number of respects, birds are still very reptilian. Now we know why.
Your last paragraph sums it up nicely.
I would be very surprised to see "macromutationism" supported by an evolutionary scientist. I cannot imagine it, if that's what it purports to be. It is certainly not what punk eek suggests.
