News from CRG
An international consortium including scientists from the Centre for Genomic Regulation (CRG) in Barcelona, presents for the first time the phylogenetic tree of modern birds based on data from genome sequencing.
The study resolves some of the mysteries surrounding bird evolution. For example, it provides a detailed bird family tree, explains the evolution of their genome, reveals the role and appearance of song in the different families, identifies when they lost their teeth, studies the relationship between the genomes of birds and reptiles like crocodiles, presents the origin of sex chromosomes in birds, and proposes a new method for phylogenetic study based on massive genome sequencing data.
The results are being published simultaneously in 8 articles in a special edition of the journal Science, on Friday December 12, and in 15 further articles in other renowned scientific publications.
