Though this is an inventive and dramatic example of three-dimensional paper construction, it does not succeed in presenting evolution in a clear or comprehensible way. Fifteen million years from the ""Cosmic Egg"" to the moon walk are summarized in 12 half-pages of text. The compression of information makes this hard to understand and subject to inaccuracies. Hawkey states that amphibians began their lives as tadpoles and had to return to the water to breed, information which is inaccurate in regard to some amphibians including salamanders. He attributes the rapid transformation of ape-like primates to ""neotony,"" a process by which ""useful features of the infant or even the unborn baby are retained in adulthood. Why this theory would explain rapid brain development or physical changes in humans is not clear. And no aids are given for difficult or specialized vocabulary. Meanwhile, paper constructions include a lurid volcano belching flames, the first fish to walk on the land, the extinction of the dinosaurs, Australopithecus killing an antelope, an astronaut on the moon, and the skull of the ""missing link."" Additional flaps and tabs clutter without adding to the whole (e.g., a tab shows what would happen to a modern city if a meteorite the size of Mount Everest fell on it), and minor problems occur with matching colors on moveable segments (Neanderthals have yellow upper torsos and pink lower ones). Children will enjoy the three dimensionable pop-outs, but will need to consult other sources for factual information on evolution.
