Wonderful illustrations and lots of fun facts, but alas, another science book carrying the water bucket for evolution. The brief research I did after reading this book shows that no fossil has been found that shows any transition from fish to amphibian. The skeletal structure of a fish could not support an amphibian, nor are the internal organs the same. These are major changes that would have taken time and thus history would show a transition. The book begins with the evolution of the frog from fish. While it is an interesting theory, it is simply that, until proven otherwise, yet rarely is it ever stated to children that these are theories. I do believe in evolution, the evolution of science, as new things are being discovered every day, and what we believe changes accordingly.
