Zig-zag patterns found on a fossilised shell in Indonesia may be the earliest engraving by a human ancestor, a study has claimed.

The engraving is at least 430,000 years old, meaning it was done by the long-extinct Homo erectus, said the study.

The oldest man-made markings previously found were about 130,000 years old.

“If this is symbolic behaviour by Homo erectus, then it’s basically the only evidence we’ve got for a species that lived for a million-and-a-half years on three continents,” he said.
