The fossil of a child’s tooth is the earliest known evidence of modern humans in western Europe, researchers say. The discovery of the molar was made in a cave – known as Grotte Mandrin – in France’s Rhone Valley.

The family of assassinated Congolese independence leader Patrice Lumumba will soon receive his only known remains – a tooth removed after his death by a Belgian man whose family apparently held on to it for nearly 60 years.
