This book takes an in-depth lookat genetic variation found in nature. The authors examine the evidence from all the different sides, compare the different theories on the issue, e.g, Darwinism, Punctuated Equilbrium, and Creation. I have read books and articles on this subject from Mayr, Gould, Stanley, Mendel, and others. This book ranks right up there in quality. Moreover it is even better in same cases as it doesn't push its dogma down your throat like some others do, but allows the reader to make up his own mind.

Take a look at this book if you have ever had any questions about speciation or biological variaiton. You may find this book hard to get a hold of but it is well worth it. Definite 5 star book.

This book was a good defense against both Darwinism and punctuated equilibrium. This was the first book I read on the subject of evolution, and although it was a bit technical, it was very explanatory. It is a good book to give to your biology professor or someone who wants a good defense of creationism without unscientific remarks. It was written by two very qualified doctorates in biology and genetics. I would like to see an evolutionist try and analyze this book for its "unscientific" behavior, which many evolutionists claim against creationists.
