But for HHMI investigator Harmit Malik and his team at the Fred Hutchinson Cancer Center, it's the genomes—not the people—that are in conflict. The lab studies rapid evolution—the genetic changes that happen in a species over a few generations rather than thousands of years. These fast changes are often fueled by genetic conflicts—competitions between different entities trying to maximize their success at the expense of another.","pubDate":"Fri, 23 Oct 2026 23:20:02 EDT","url":"https://phys.org/news/2026-10-surveying-genetic-battlefield-uncover-rapid.html"},"indexado":"2026-10-24T03:21:22.181Z"}}
