Our human ancestors may not have been the first to spearhead new technologies millions of years ago. It would seem other hominins were crafting tools 700,000 years before previously thought.

Lead study author Sonia Harmand of the Turkana Basin Institute at Stony Brook University says that the tools, “shed light on an unexpected and previously unknown period of hominin behavior and can tell us a lot about cognitive development in our ancestors that we can't understand from fossils alone,” according to science news site Phys.org.
