Notes:
The term Gondwanaland was coined by geologist Eduard Suess after the forested, gondwana regions of India where the fossilized evidence of this megacontinent was first found. Alfred Wegener’s theory of continental drift suggests that about 280 million years ago, our globe’s landmass was a single supercontinent called Pangea. Pangea split roughly 200 million years ago into two landmasses known as Laurasia and Gondwanaland. Gondwanaland comprised Antarctica, South America, Africa, Australia, New Guinea, and the Indian subcontinent which have now moved into the Northern Hemisphere.

Notes:
Africa is home to a variety of cuisines and food crops, but root crops such as yams, cassava, and sweet potatoes are predominant. These crops are vital for nutrition and food security in many African countries because they are high in carbohydrates, adaptable to various climatic and soil conditions, and have high yield potential. This makes them the primary source of caloric intake for many Africans, contributing significantly to the agricultural economy of the continent.
