human tool use

The use of tools - taking inanimate objects and using them to solve a problem - was, until relatively recently thought of as being an exclusively human skill.
Spanning the past 2.6 million years, many thousands of archeological sites have been excavated, studied, and dated. Humans are especially good at solving problems using two tricks: language (to induce others to act as they want) and tools (to achieve what they cannot do with hands alone). Humans First Used Tools to Eat Meat 250,000 Years Ago. The manufacture and use of tools was once believed to be uniquely human, but we now know that we share this ability with some animal species, although it seems rare. Humans weren’t the first to make or use stone tools. That honor appears to belong to the ancient species that lived on the shores of Lake Turkana, in Kenya, some 3.3 million years ago. Stone tools and other artifacts offer evidence about how early humans made things, how they lived, interacted with their surroundings, and evolved over time. Introduction. Here’s What the Discovery Means Top chef: a blade used by pre-humans that tested positive for rhinoceros blood The Stone Age marks a period of prehistory in which humans used primitive stone tools. The most sophisticated chimpanzee tools are small, slender tree branches from which they strip off the leaves. To that effect, I offer a systematic comparison between humans and nonhuman primates with respect to nine cognitive capacities deemed crucial to tool use: enhanced hand-eye coordination, body schema plasticity, causal reasoning, function representation, executive control, social learning, teaching, social intelligence, and language. - The evidence -- butchered, fossilized bones -- dates to roughly 3.4 million years ago.

Tool Making.

Lasting roughly 2.5 million years, the Stone Age ended around 5,000 Tool use has long been considered a uniquely human characteristic (Oakley, 1956), dating back 2.5 Mi years (Ambrose, 2001).However, there is now general agreement that chimpanzees also use tools, in captivity (Kohler, 1927) as well as in the wild …

The ability to recognize, create, and use complex tools is a milestone in human evolution. THE GIST - The earliest known evidence for stone tool use and meat eating among early humans is found. For a long time, tool use was considered a quintessentially human activity, but decades of research has exposed that as simply untrue. The nature of the cognition underpinning uniquely human tool-use is still hotly debated, but one thing is clear, understanding the cognition underpinning animal tool use is a critical piece of the puzzle. Some chimpanzee communities are known to use stone and wood as hammers to crack nuts and as crude ineffective weapons in hunting small animals, including monkeys.However, they rarely shape their tools in a systematic way to increase efficiency. Widely distributed brain regions in parietal, frontal, and temporal cortices have been implicated in using and understanding tools, but the roles of their anatomical connections in supporting tool use and tool conceptual behaviors are unclear. Tools are mechanical implements that allow individuals to achieve goals that otherwise would be difficult or impossible to reach.
