The evolution of animal genomes - Review by Casey Dunn
Genome sequences are now available for hundreds of species sampled across the animal phylogeny, bringing key features of animal genome evolution into sharper focus. The field of animal evolutionary genomics has focused on identifying and classifying the diversity genomic features, reconstructing the history of evolutionary changes in animal genomes, and testing hypotheses about the evolutionary relationships of animals. The grand challenges moving forward are to connect evolutionary changes in genomes with particular evolutionary changes in phenotypes, and to determine which changes are driven by selection. This will require far greater genome sampling both across and within species, extensive phenotype data, a well resolved animal phylogeny, and advances in comparative methods.
