Some baby spiders can float for tens or even hundreds of miles, buoyed by strips of silk and carried aloft by the wind. But even for these resourceful youngsters, making a journey of more than 6,000 miles across choppy ocean sounds fairly improbable. That’s why researchers have long assumed that one genus of spider found in both Africa and Australia must have ended up on both continents tens of millions of years ago, as supercontinent Gondwana slowly cleaved apart.

A new genetic analysis challenges that scenario, however. Remarkably, scientists now argue that these arachnids actually made the pilgrimmage via makeshift rafts, long after the modern continents had been established.
