A month ago we posted - Oldest Stone Tools? - the announcement of possibly the oldest stone tools ever. The discovery was reported at a scientific meeting in San Francisco and has been followed up with a paper published this week in the journal Nature.
This find raises fundamental questions: Who made these tools? What does this say about Homo as the putative originator of stone tool technology? Is it possible stone technology originated deeper in time than even this early date of 3.3 million?
Check out a variety of online commentary on these questions by reading the following
One. 3.3-million-year-old stone tools from Lomekwi 3, West Turkana, Kenya in Nature
Two. An accompanying article, Archaeology: Tools go back in time by archeologist Erella Hoovers
Three. A description of Kenyanthropus platyops, possibly the maker of these earliest tools.
