Test My Theory: Macro evolution DOES happen?

[Amarok]

I think it's a tough definition to pin down.  What is macroevolution?  Is it a crocoduck?  Is it the appearance of a new species?

The theory of evolution does not allow for sudden, unprecedented changes in a life form.  If we were to observe that happening (ie, crocoduck) then the theory would have sprung a very serious leak.  As for two-headed animals, that's a mutation that seems to pop up now and then but doesn't seem to confer many benefits.

indeed

if it's a cocoduck then there demanding a miracle not evolution

if it's just a new species then it's been witnessed a hundred times

if there demanding to see a non avian dinosaur become an avian then ask them if they have a few million years if they complain that it can't be observed then remind them were talking about populations and genetics which don't work at our fuss
