Shell may be oldest evidence of geometric art: our Homo erectus ancestors may have been smarter and more creative than we thought.

An online article by Brandon Keim for the National Geographic - World's Oldest Art Identified in Half-Million-Year-Old Zigzag - questions whether our Homo erectus ancestors may have been smarter and more creative than we thought.
A zigzag engraving on a mussel's shell is raising questions about the defining human capacity: artistic creativity.
The earliest evidence of geometric art was dated from 70,000 to 100,000 years ago; scratched into rocks found in South African caves, the engravings signified behavioral modernity: Homo sapiens' unique cognitive journey into a world of abstraction and symbol.
However, the recent analysis of the shell excavated from a riverbank in Indonesia thought to at least 430,000 years old was not made by humans - Homo sapiens.
This artist appears to have been one of our ancestors, Homo erectus, not previously associated with artistic and symbolic behaviour.
Archaeologist Josephine Joordens of Leidens University in the Netherlands and colleagues published their findings in Nature.
The engraving belongs to a trove of fossils unearthed in 1891 by Dutch paleoanthropologist Eugene Dubois. Among them were the first specimens of what Dubois called Pithecanthropus erectus, later known as Homo erectus. Dubois, however, did not describe the engraving.
Joordens's group, which now numbers 21 researchers, has now dated the shell to between 430,000 and 540,000 years ago. They have ruled out alternative explanations for the engraving and for holes in other shells that suggest they were opened by a tool.
