Final answer:
The Oldowan stone tool industry, dating from about 2.5 to 1.5 million years ago, is most associated with Homo habilis, which was present during that time and linked to the creation and use of these tools.
Step-by-step explanation:
The Oldowan stone tool industry is considered to be the oldest known stone tool industry, and these tools are most commonly associated with Homo habilis. Oldowan tools date from approximately 2.5 to 1.5 million years ago (MYA), a time when several hominins were present in Africa. The evidence points to Homo habilis, as they appear in the archaeological record between 2 to 3 million years ago, and were likely to be the creators and users of these tools. Moreover, Homo habilis is often referred to as “handy man” due to their association with stone tools found with their remains.
