Weapons carved from human bones come from a drowned land bridge between Britain and Europe

About 11,000 years ago, Stone Age hunters made sharp weapons from human bones, new research reveals.

These hunter-gatherers lived in Doggerland, a now an underwater region in the North Sea which connected Europe with Britain. At the end of the last ice age, when the sea level was lower, herds of animals and people lived in it. Although these people have long since disappeared, artifacts from their culture, including bone weapons, are often dumped ashore in the Netherlands.
