Here is your answer
*Early humans may not have needed to continuously reinvent the proverbial wheel.
*A newly discovered cache of stone tools representing 11,000 years of human habitation suggests that perhaps human innovations didn't flicker in and out of early human history as once suspected, driven into obscurity by external pressures such as climate change.
*Instead, researchers suggest, at least some ancient humans apparently managed to pass an innovative type of stone tool down to their descendants.
*Other researchers welcome the additional evidence of ancient technological know-how, but say that other sites show that such technologies do indeed appear and disappear across human prehistory.
*The new find amounts to a few dozen slivers of stone, slightly curved on one edge, that are only a few centimeters long on average.
* But they are tens of thousands of years old, and the product of the longest and most complex known manufacturing process devised by early Homo sapiens.
*The stone slivers, which were excavated from the Pinnacle Point caves on South Africa's southern coast, are actually sharp miniature blades that would've been incorporated into arrows or other projectile weapons.
*Crafting the blades, the researchers argue, was a long, painstaking process that included using a primitive kiln to heat the stone, making it easier to shape.
* Only humans who'd evolved sophisticated thought could've been up to the task, the researchers say.
"When we find these complex-recipe technologies, that's a signal that people have complex cognition," says paleoanthropologist Curtis Marean of Arizona State University, Tempe, and one of the paper's authors.

The earliest stone toolmaking developed by at least 2.6 million years ago. Early man needed tools to fulfill their different purpose. They use different kind of rocks tools cutting, hunting and for safety purpose.
- They used spares, arrows, sharpened rock tools and antlers for hunting small and large animals.
- They also learned tools for weaving and made clothes.
A tree limb could be given a sharp point making it usefull for cutting as well as simple percussion. Again these tools could have dual purposes as a tool and aa a weapon.
Hence, Tool making was one of the best development in early time.
