Lect 30: Genome Evolution Mike Webster msw244@cornell.edu Thanks for listening! The Genomics Revolution Recent advances in our ability to collect DNA sequence data are revolutionizing biology. The Genomics Revolution Recent advances in our ability to collect DNA sequence data are revolutionizing biology. Go deeper: Can examine entire genomes, not just specific genes Go broader: Sample homologous sequences from MANY different organisms The Genomics Revolution Consequences for studying biodiversity: NOW we can study: Evolution of genome size Natural selection & genes Genetic adaptation, changes within & between species
