The fictional planet of Darwin IV is a beautiful and interesting place for any wildlife artist (sauch as Mr. Barlowe). His artwork is fabulous and the individual animals are interesting and workable. However, although the animals are inteesting in and of themsleves, besides certain universal features (like the absence of eyes and jaws), they seem to have nothing in comman. While all Earlthly land vertibrates have or had four limbs (hece the name terapods). Barlowe's creations all seem to have different numbers of limbs and no explanation is given as to why. There is also none of the intricate ecosystems that grace Earth. It seems that Mr. Barlowe has created many different biotas and crammed them together on one planet. I suggest this book for fun and for its great artwork, but not for it's scientific value.
