This book is great for a AP Bio or Psychology elective course for juniors and seniors in high school. I use it in my zoology course. You can pick and choose chapters and the students will definitely give you feedback. I found it like the classic book, " Microbe Hunters" but this time animal experimentors and their work. Sure to start discussions on ethics and how much we owe to our underlings, the animal kingdom. To me, they will never be underlings but living and breathing organisms like us who share our planet and who have taught us much about them and ourselves. The only shortcoming of the text (reason for only 4 stars ) is that more photographs could have been used ( especially of the scientists ) and some background on the scientist ( birth, country, death etc. ) to start each chapter would have helped. I am planning a book called "Through Their Eyes" which will include all zoologists and their work and which will also take us out of the laboratory setting into the field. Aristotle to Conrad Lorenz to Dr. Jane Goodall. It will bring this volume full circle. "Underlings", ha, how about equals?
