  • Worm-eating mice reveal how evolution works on islands
    on May 16, 2018 at 12:56 pm

    When animals are isolated on islands, they can evolve into strange new species found nowhere else on Earth. But what's the cut-off -- how small can an island be and still support the evolution of multiple new species from a single common ancestor? A family of worm-eating mice from a tiny island in the Philippines have set a new lower limit for island size and evolution. […]
