From the cup of coffee that jumpstarts the day to dangerously addictive drugs, the recreational use of plants with psychoactive properties has a long history among humans. But, as with many things, it turns out that other animals got there first. From parrots to primates, consuming medicinal chemicals is an instinctive behavior that helps countless organisms fight infection and treat disease. But the similarities don't end there: Like us, many creatures also consume substances that have no apparent benefit . . . except for inducing intoxication. In fact, animals have been using drugs for recreational purposes since prehistoric times. We may even have animals to thank for the idea-legend says that coffee was discovered by observing the behavior of goats that had eaten it. In his previous book, Strange Survivors, author and biologist One R. Pagan introduced readers to some of the truly bizarre strategies animals use to survive in the cutthroat world of natural selection. Now, in Drunk Flies and Stoned Dolphins, he sheds light on the surprising cravings they indulge when it's time to unwind. In this book, you'll get an eye-opening glimpse into the mind-altering behavior of the non-human members of the animal kingdom, spanning insects to elephants-including the dolphin species that apparently likes to pass around an intoxicating pufferfish as if they were sharing a joint. Combining fascinating science with humor and enthusiasm, Pagan's latest is full of the kind of unforgettable stories and odd facts that you'll find yourself repeating to everyone you meet. From fruit fly happy hour to the evolutionary reasons behind nature's drugs, Drunk Flies and Stoned Dolphins takes you on a trip through the colorful world of animal intoxication-and along the way, explores what this science reveals about the surprising connections between all the world's creatures.

Planarians, a class of flatworm, are extraordinary: they possess the remarkable ability to regenerate lost body parts, including complete regeneration of the nervous system. If cut into pieces, each piece of the planarian can regenerate into a complete organism. They are also unique among invertebrates in that they display addiction-like behaviors to many drugs abused by humans. Because of these distinct neurological traits, the planarian is often used as an animal model in neurological research, being used most recently for developments in neuropharmacology. The First Brain is a discussion of how planarians have been used in neuropharmacology, and what role they have played in scientific developments that have a high impact on our culture. Planarians have been the animal models for research in drug addiction, antidepressant development, and various other topics in biology, neurobiology, and even zoology. Pagan uses these flatworms as a framework to explore the history of biological research. The book provides accessible background information on how biomedical research is impacted by evolution, and defines neurobiology and neuropharmacology in ways that are easy to understand. At the same time, Pagan provides enough detail for the book to useful for scientists working in various subsections of biology. The planarian has played a key role in the history biological, neuropharmacological, and zoological research, and has even made appearances in a few unexpected places in popular culture. One Pagan explores all these roles, and shows us why the planarian truly is one of the most extraordinary and influential organisms in scientific research today.
