What is the author's tone in Wonderful Life: The Burgess Shale and the Nature of History by Stephen Jay Gould?

Stephen Jay Gould is a famous science writer. He has written in any number of venues, from the most academic to the most popular. For this reason, he acquires the capacity to write about complex topics with the energy of a child opening presents for Christmas. Gould is wholly enamored with what he calls "the Burgess Drama." For him, the story of the drama is absolutely fascinating, from its beginnings with Walcott's discovery and misconception to the revision that came during the 1970s through the work of Whittington, Morris and Briggs. He begs the reader to pay close attention to the scientific details so that they can see the beauty of the Burgess revision as clearly as he does. He argues that the Burgess revision must be appreciated at a deep level in order to receive its full effect.
