The research team including IU emeritus professor David Dilcher and some of his Indian colleagues found fossils of leaves of the sweet potato family in Eastern India. The leaf fossils belonged to the morning glory family, to which the tuber belongs and are 57 million years old. The family of plants is now said to have originated in the East Gondwana land mass, during the late Paleocene epoch. The part of the Gondwana land where the plant first grew, later became a part of Asia. Previously, the fossil evidence has suggested that the morning glory family was born in North America, about 35 million years ago.
However, there is little evidence about whether sweet potatoes in specific were growing in that region or whether they resembled the food that we know and eat today. This is because the leaf fossils found by the researchers belongs to the Ipomea genus of the morning glory family and this one genus includes sweet potatoes and hundreds of other plants as well. Regardless of the uncertainty that surrounds the origin and native country of the sweet potato, it's easily one of the most important root vegetables around the world. This is because it's not just nutritious, but also easy to grow and harvest.
Sweet potatoes are also great in taste, easy to cook and very versatile. You can easily experiment with them in various ways and eat them as snacks or a whole meal. They are full of vitamins and other essential nutrients like potassium, calcium, magnesium, manganese, etc.
