Stone tools are part of the lower paleolithic, and systematic stone tool production appears in the fossil record around 2.5-2.6 million years ago. These early stone tools are called Oldowan. If you look at the "Time line of human evolution" in the back cover of your textbook, figure 10.32 (Hominin Lineages), or compare the dates of fossil specimens from the lessons and your textbook, you will notice that there are several named species alive at 2.5 mya. Provide a list of species that were present at around 2.5 mya. Which of these species is most likely to have first made Oldowan tools? Why? For what purposes might the Oldowan tools have been used?
