On Graham Hancock's site I saw another news item that reminded me of the evolutionary jump presented by "2001: A Space Odyssey".
Although we consider the use of tools to be a main difference between human beings and other life, there are many animals that have learned to use tools for specific tasks.
Although they are certainly not building particle accelerators or spacecraft, clearly other primates have the ability to intelligently manipulate their environment to achieve predetermined goals.
In fact, chimps have even been able to recognize dangerous human technology, in the form of snares, and sabotage them.
Regardless of the capacity that other life can use tools, it is clear that technology defines us as human almost as much as any other factor.
