Learning from nature

                                                        Learning from nature

long ago, people began observing animals, birds, insects and plants. many things that they saw surprised them. they wondered if they could use what the saw.

they saw the sharp teeth of the tiger, the huge curved tusks of the elephats and the long beak of the woodpecker.

by chipping off bits, the stone turned into a pointed knife. this stone knife was tied onto a long stick, and it became the longest claw. this was the primitive spear.

this spear was used for hunting and for protectionfrom wild animals.

stone bone and shells were flattened and sharpened to make cutting tools, much like the sharp front teeth of rats.
