This is part of its efforts to popularize science to the general public and students who are pursuing science as their career. TNSF attempt to focus on students on higher science as everyone knows that learning of science at college within the curriculum is not enough to acquire holistic knowledge of science at the appropriate time. Hence, to fill the gap between what students are acquiring through the curriculum and what it is required, TNSF is planning its activities on higher science to students who are pursuing higher education.

About the Lecture
Human beings are closely connected with the biodiversity around them. They directly use these plants and animals for food, medicine, clothing, and shelter. In ancient times, the places where people lived determined what they ate. Many plants and animals we use today might have been completely unknown in India in the past. For instance, we know that potatoes were brought from the Americas by the Portuguese and the English. Could not these plants have been found in both India and the Americas before they were introduced here? How do we know this this? What other plants and animals that we use are like potatoes? Could we not make Chettinad chicken if we lived in Ponniyin Selvan times? Why is this even a question?
In this talk, we will examine how the ideas of Charles Darwin and Alfred Wallace affect the way we think about the history and geography of living beings. We will try to find out whether or not we could have made and enjoyed a specific recipe of Chettinad chicken if we had lived in the 10th century CE.
