Final answer:
True, the Oldowan tools were indeed named after Olduvai Gorge. They are the earliest known stone tools, dating back to between 2.5 and 1.5 million years ago and are significant for their basic designs and methods of creation.
Step-by-step explanation:
The statement that Oldowan tools were named after Olduvai Gorge is True (A). The Oldowan is the oldest known tool industry, dating from about 2.5 to 1.5 million years ago. These tools were fairly basic and made using hard hammer percussion to chip away flakes from a stone, leaving a core that was used for various purposes such as cutting meat and plants. Mary Leakey was instrumental in classifying these tool assemblages based on their utility. The Oldowan tools are a significant milestone in human evolution, representing the earliest evidence of 'flint knapping,' a technique that became more complex over time.
