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
