If your children don't want to brush their teeth, just tell them this: even Neanderthals did it!
Two molar teeth of around 63,400 years old show that Neanderthal predecessors of humans may have been dental hygiene fans, the Web site of newspaper El Pais reported on Tuesday.
The teeth have "grooves formed by the passage of a pointed object, which confirms the use of a small stick for cleaning the mouth," Paleontology Professor Juan Luis Asuarga told reporters, presenting an archaeological find in Madrid.
