GG. cool article. This is a great thread!!

I posted this in the Education thread back in December.  Now the data interpretations and earlier analyses are starting to trickle out (see the 3 links at the bottom).  One funny fact, at least I found it amusing, is that peregrine falcons are more closely related to parrots than hawks.  A parrot on steroids!  ;)

This is big!  HUGE!  28 or 29 (!) papers are being published today, all publicly available, about a major accomplishment - the genome sequencing of 48 bird species, including eagles.

A flock of genomes:  http://www.sciencemag.org/content/346/6215/1308.short

Here's a summary of this incredible research.  'Big Bang' of bird evolution mapped: Genes reveal deep histories of bird origins, feathers, flight and song:  http://www.sciencedaily.com/releases/2014/12/141211142136.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29

Of particular note was this:  What happens to species facing extinction or recovering from near-extinction? Birds are like the proverbial canaries in the coal mine because of their sensitivity to environmental changes that cause extinction. In a Genome Biology study led by Shengbin Li, Cheng Cheng and Jun Yu from Xi'an Jiaotong University and Jarvis, researchers analyzed the genomes of species that have recently gone nearly extinct, including the crested ibis in Asia and the bald eagle in the Americas. They found genes that break down environmental toxins have a higher rate of mutations in these species and there is lower diversity of immune system genes in endangered species. In a recovering crested ibis population, genes involved in brain function and metabolism are evolving more rapidly. The researchers found more genomic diversity in the recovering population than was expected, giving greater hope for species conservation.
