COVER Genomic information illuminates our history, from the primordial mammal (center) to human migrations, and our future. In a chart and in a review on p. 458, comparative genomics is used to highlight the similarities and differences between extant mammalian species. Features in the Genome special section (beginning on p. 443) and related items include improvements in technology and efforts to extract meaning and benefit from the DNA sequence.
