Re: New Zealand's Giant Eagle Showed Rapid Size Gain ???

What is the fossil record like for the Australian mini-eagle?  Not to play 
devils advocate, but couldn't the australian eagle have been undergoing a size 
squeeze the last few million years?  Or perhaps the common ancestor was in the 
middle some where, with the two descendent linneages evolving in opposite 
directions?  In that case the size change wouldn't be nearly as rapid, 
(although still impressive).

Don't get me wrong, it's a sweet study either way, I'm just not sure that the 
authors thought through all the possibilites when determining the rate of 
evolutionary change.
