  • For years, conservationists have been concerned about the impact of invasive plant species in the Galápagos Islands. Hundreds of species have been identified as being nonnative, introduced through human contact. The idea is to remove these plants to help keep the archipelago ecologically pristine.

    That’s a worthy goal. But there’s just one problem, according to a study in Science: some of these pariah plants turn out to be native after all. They predate humans in the Galápagos by thousands of years.
