（单词翻译）

Darwin's fabled1 isles2, the Galapagos, are in need of a makeover. And removing invasive species of plants tops the to-do list for the islands’ restoration. But six species that were set to be exterminated3 have gotten a reprieve4. Because a new study finds that they’re actually natives.

 

The species were all thought to have been brought to the Galapagos by European travelers 500 years ago. But, by examining fossilized pollen5 and other plant remains6, an international group of scientists found traces of each species dating back many thousands of years. Their discovery is reported in the November 21st issue of the journal Science.

 

Since millions of dollars are spent worldwide each year in battles against invasive plants, the researchers say that conservationists need to step back and reconsider what really belongs. Such deliberation is especially true in areas with high biodiversity, where thousands of different species can make an accurate ecological7 history hard to come by. That means paleobotanical input—the consideration of plant fossils—could play an important role in future eco-restorations. Because those who don't know history are doomed8 to replant it.

 

Thanks for the minute for Scientific American's 60-Second Science. I'm Adam Hinterthuer.
