Jared Diamond's theory

I agree with Jared Diamonds thesis that the way our world has come to be based on crops and animals has to do with agricultural luck. Before farming people used to go from place to place and hint for good, building a home wherever meet was plentiful. After the ice age and farming was introduced, people started adapting and never looked back at their old way of life.

In some places, agricultural didn't come as easily. In Eurasia, although, crops grew nutritious and strong, getting an equal and steady balance between sun and rain. They learned how to control which food grew when and where. Soon, they started to domesticate animals; using them not only for meet but some became their beasts of burden and others, were used for milk, eggs, wool, and even their dung was used as fertilizer.

For the land of Eurasia transforming to agriculture was easy. However, to lands like New Guinea adapting to this new way of life was much more difficult. In new Guinea crops didn't flourish and even if so, they had no appropriate animals to help pull the plow or dung to keep the soul rich. The people here had to keep to the old hunter an gatherer life style. Even today their are still places one may see that life style being used.

Luck of the land played a major role in determining which lands were successful between the lands that never changed.
