Brand new research turning the taxonomy of birds on its head!

There's a long and detailed summary of Hackett et al's paper here (on Living the Scientific Life, posted by GrrlScientist):

http://scienceblogs.com/grrlscientist/2008/06/early_birds_shake_up_avian_tre.php

A quote from the introductory part:

"So why is avian taxonomy suddenly in such a state of upheaval? The precise evolutionary relationships between major groups of birds have long been contentious because they underwent an explosive radiation event sometime between 65 million and 100 million years ago. Nearly all of the major avian groups arose within just a few million years -- a very short period of evolutionary time. As a result, those groups of birds, such as parrots, doves and owls, that are united by distinct morphological characteristics seem to have appeared suddenly because there are few, or no, known evolutionary intermediates that provide clues to their deeper relationships with other avian groups.

"These new findings are important because much of our scientific knowledge about reproductive biology, speciation, behavior, ecology, and natural history of animals is based on our studies of birds, so these data provide a new evolutionary framework that can be scientifically tested for decades to come."

The paper itself (A Phylogenomic Study of Birds Reveals Their Evolutionary History by Shannon J. Hackett et al) can only be read through a subscription to the AAAS journal Science. What a pity -- these wretched science publishers all charge an arm and a leg to read their stuff. The abstract page is here:

http://www.sciencemag.org/cgi/content/abstract/320/5884/1763

There's wonderful stuff here. The smelly Hoatzin is apparently still a mystery (". . just what is this creature??"). And I am still left longing to know what the phylogenetic relationships of the Columbiformes are -- again, apparently unresolved.

Read the comments that follow too -- some well informed and illuminating.

PS: Owlboy, anywhere you know where a summary of their work on owls can be found??

PPS: Thanks, raptortrnr, for that post!! I'd heard the news but little else.

You should Email it to Deane. You can PM Deane if you don't know his Email address. I don't want to post it publicly
