Arthropods comprise the largest and most diverse phylum on Earth and play vital roles in nearly every ecosystem. Their diversity stems in part from variations on a conserved body plan, resulting from and recorded in adaptive changes in the genome. Dissection of the genomic record of sequence change enables broad questions regarding genome evolution to be addressed, even across hyperdiverse taxa within arthropods. Using 76 whole-genome sequences representing 21 orders spanning more than 500 million years of arthropod evolution, The Richards lab documents changes in gene and protein domain content and provides temporal and phylogenetic context for interpreting these innovations. These analyses demonstrate how large-scale comparative genomics can provide broad new insights into the genotype to phenotype map and generate testable hypotheses about the evolution of animal diversity.
