Athletic frogs have faster-changing genomes

Durham, NC — Physically fit frogs have faster-changing genomes, says a new study of poison frogs from Central and South America. Stretches of DNA accumulate changes over time, but the rate at which those changes build up varies considerably between species, said author Juan C. Santos of the National Evolutionary Synthesis Center in Durham, North Carolina. read more
