Spears Pre-dating Humans
As my title suggests, stone-tipped spears were recently found at Gademotta, a stone-age site in Ethiopia (Viegas), that have been dated to 280,000 years ago, over 80,000 years before the first fossils of our species are dated to. This could mean that the spear had been used much earlier than scientists originally thought, and that a predecessor species had the intelligence and craftiness to fashion a spear before homo sapiens had evolved. According to the article, this could drastically change our evolutionary tree.
