Book excerpt: Are animals designed economically? The theory of symmorphosis predicts that the size of the parts in a system must be matched to the overall functional demand. Weibel shows how animals as different as shrews, pronghorns, dogs, goats--even humans--all develop from essentially the same blueprint by variation of design.
