Query: An absolute inspiration

I always thought biology was no more than stamp collecting and memorization of names in a dead language. This book changed my mind. The book is thoughtful, full of examples and results from other studies. The writing is smooth and easy to understand. I particularly like the part on evolutionary genetics. Here Ridley made the insights from evolution theory rigorous by introducing some simple models from population genetics. Simple yet rigorous. Anyone with highschool math can understand.I think it's a very good place to start when you want to learn more beyond those popular science books on evolution.
