Exploring Malta’s submerged ice-age land bridge to Sicily

As glaciers formed and sea levels fell over hundreds of thousands of years, land bridges occasionally linked Malta to neighboring islands and the European and North African mainlands, News from Science reports. Animals—and potentially even humans—may have crossed those bridges, though the timing and routes remain mysterious. Marine geologists have taken samples and deployed seafloor sensors to investigate a bridge to Sicily from the last ice age. Some answers could lie more than 100 meters underwater.
