Long ago, during the Age of Stone, the forest was thick, wild, and full of danger. Tall trees blocked the sun, and the ground was covered with roots, rocks, and fallen leaves. Among all the creatures living there was a black crow named Kaka. He was not the strongest animal, nor the fastest, but he was known for something special—his sharp mind.

Kaka spent most of his days watching the world carefully. From the tops of trees, he observed other animals hunting, hiding, and surviving. Most interesting of all were the humans who lived near the edge of the forest. They were strange creatures who walked on two legs and used stones in clever ways.
One day, Kaka saw humans surrounding a large animal they had hunted. They used sharp stones to cut meat and break bones. Kaka noticed how the stones had edges that made hard things easy to open. He tilted his head and watched closely, memorizing every movement.
Later that day, Kaka found a hard nut on the forest floor. He pecked at it many times, but the shell would not break. Normally, he would have flown away, but this time he remembered the humans and their stones.
Carefully, Kaka picked up the nut in his beak and flew to a place where sharp stones lay on the ground. He dropped the nut from high above. It hit the stone and cracked open. Kaka cried out happily and ate the food inside.
The next day, Kaka repeated the trick. Other birds noticed and gathered around. They watched him drop nuts, shells, and even small bones onto stones. Soon, they began copying him.
Over time, birds across the forest learned this new skill. Food that was once impossible to reach became easy. The forest grew quieter, as animals no longer fought as much over food.
Even humans noticed the birds behaving differently. They saw crows using stones just like them. Some humans believed the forest spirits had taught the birds.
Kaka became respected among animals. He did not rule by force, but by teaching. He showed them that thinking and learning were as powerful as claws and teeth.
From that day on, the Stone Age forest changed forever. Animals learned that survival was not only about strength, but about observation, memory, and intelligence.
And high above the trees, Kaka the crow continued to watch the world, always learning, always thinking.
