2016 was a difficult year and 2017 doesn't stand to get any better, so here's the bad news -- the ghost spiders have flown over to a remote island, evolving into new species scientists were previously unaware of. In order to fly, spiders use a technique called ballooning, turning their silk into a sort of kite that takes them long distances. National Geographic reports that a new study finds that ghost spiders -- named for their light complexion -- ballooned themselves to the famous Robinson Crusoe Island and have since evolved at a rapid pace.
