Nourishments of Ancestors

In very early ages most important need of people was food. They got it supplied by hunting animals. They hunted animals using spears, arrows & bows. People who lived near rivers practiced fishing using spears. With the invention of nets, they used nets for fishing. 

The problems they faced were injuries while hunting and inability to hunt and pluck fruits in winter. Gradually they started animal farming and crop cultivation. then they stored surplus of food for difficult times. Again, they had to work hard and need more energy. As a solution for that problem they made simple instruments using stones and started to use animals like bulls and dogs to facilitate their work.
