Query: evolution of scientific thought and knowledge

This book is full of well known and obscure scientific discoveries and something that surprised me was the bickering and infighting within the scientific community over the centuries.The subject matter is handled with wit and easily understood. Science is not my usual reading fare and I somehow got through it.The place of Homo sapiens in the world was somewhat humbling and their wanton destruction of species a bit unsettling. I recommend this book.
