In this Hugo-nominated novel, an alien walks into a museum and asks if he can see a paleontologist. But the arachnid ET hasn't come aboard a rowboat with the Pope and Stephen Hawking (although His Holiness does request an audience later). Landing at the Royal Ontario Museum in Toronto, the spacefarer, Hollus, asks to compare notes on mass extinctions with resident dino-scientist Thomas Jericho. A shocked Jericho finds that not only does life exist on other planets, but that every civilization in the galaxy has experienced extinction events at precisely the same time. Armed with that disconcerting information (and a little help from a grand unifying theory), the alien informs Jericho, almost dismissively, that the primary goal of modern science is to discover why God has behaved as he has and to determine his methods.
