Life Everlasting is not quite what it appears, maybe the book's marketing is off a notch, or the enigmatic nature of the material beggars description. Much of Mr. Heinrich's book is actually a journal of his observations, deer and squirrels decomposing, and the various scavengers that make it happen. The author experiments with beetles, vultures, and ravens, attempting to ascertain how they find their food. A fairly light read at 200 pages, Bernd Heinrich utilizes sidebars to venture into territory that may be fresh for some readers, such as the role of scavenging versus hunting in human evolution (oh and don't get involved in that debate; various intellectuals will threaten you with pencils and other sharp objects!) The same analysis is made for Tyrannosaurus, and again, see above bracket for caveat. Not many books cover whale falls, the term used to decribe dead whales sinking into the ocean depths where they subsequently host an extraordinary assemblage. If dung beetles, scarabs, and exploding deceased cetaceans interest you, then by all means, pick this one up.
