The INSA generously met the travel of its fellows and also provided honorarium. All those who delivered lectures under the said scheme were also requested to submit summary or full length articles along with a video CD to INSA. The lectures are held in different areas of science by various fellows since then. In one of the Officers’ meeting of INSA an idea was generated to compile such lectures in the form of an e-book and make it available free on the INSA website to serve as supplementary reading material for students and teachers all ove the country. The President of INSA, Prof. R. Gadagkar desired that l compile the lectures held in the field of biology. I gladly agreed to do so. Then I wrote to all the speakers seeking their writeup, expanded summary or full length article in a popular format vis-a-vis the actual lecture delivered and indicate a few papers/books for additional reading in the form of “Suggested Reading”. I finally received 22 articles of lectures delivered during the financial year 2012-2013 and 2013-2014 which are compiled here. I wish others also responded by submitting their articles. However, if the writeups are received in future they could be compiled in the subsequent volumes in this series. These articles are very useful to biology students/teachers as well as to nonspecialist readers outside the realms of biological sciences. They are intended to generate interest in the subject and also provide basic information. I am thankful to INSA for giving me an opportunity of compiling and editing this e-book. I have greatly enjoyed reading the articles presented in this book. I am sure you too will enjoy reading them. May 25, 2015 Dharwad S. K.
