Is there any elementary tool/technology that human created/used but is not available in nature in any form?

Question

Dont ans. like IT or bio-technology!!

Answer 1

Spears and axes?

Although you could argue that they are extensions of knife usage. I suppose spears could have come about by watching bamboos and sticks being tossed around in a storm and impaling things. I can't think of how the axe occurs in nature.

Answer 2

Matter and energy could neither be created nor destroyed; though we may change one form into another. If this is true, as has been so far understood (yet to be proved otherwise), this question has only a negative answer.

Answer 3

Presumably you mean some stone aged technology.  I would think fishhooks would be something that is completely novel in form since no other animal uses it that I can think of.  Since chimps have been seen to develope primitive spears, I probably would exclude those.  Needles for sewing might be another.  Clothing itself is pretty cool if you want to stay warm.  It is a pretty good invention to use some other animals insulation.

Answer 4

why do you ask a question knowing the answer?

don`t you know that we can`t create anything?

all we do is transform...

Answer 5

the wheel

Answer 6

Flint arrowheads.

try just picking up a random piece of flint and doing it- won't work.
