When the first platypus specimen reached England from Australia in 1799, the scientific community claimed that it was a hoax. On closer investigation, dubious European naturalists eventually declared it to be real, though in an age obsessed with classification, the category-defying platypus sparked heated debates across Europe for a century. In Platypus, Ann Moyal provides a unique biography of one of the world's most famously strange creatures and tells the incredible story of how it became the focus of the great scientific debates of the nineteenth century. Eloquent and concise, Platypus uncovers the earliest theories and latest discoveries about this delightfully odd member of the animal kingdom.

Consider the Platypus, that curious Australian creature that seems neither fish nor reptile nor mammal, but that has characteristics seemingly borrowed from all over the animal kingdom. Charles Darwin certainly did, puzzling over the platypus in the light of the rest of the world's creatures, and remarking, "Surely two distinct Creators must have been at work." Australian historian of science Ann Moyal offers plenty of natural-historical information on the platypus in this slender, enjoyable book. What's more, she examines the sometimes shocked reactions the platypus inspired in European naturalists when they first saw specimens of the creature at the dawn of the 19th century. For, Moyal writes, the platypus almost single-handedly (or, perhaps better, single-web-footedly) overturned the prevailing classification of animals according to great-chain-of-being models; with its hodgepodge of physical traits and behaviours, it offered "an unexpected bridge between the categories of mammal/quadruped and reptiles and birds". That bridge helped set evolutionary theory on a new course; as Moyal writes, the platypus played an explicit role in Charles Darwin's ideas on isolation, species diversity, and natural selection, and he branded it a prime example of a "living fossil" that had managed to find an unoccupied ecological niche and live relatively undisturbed, while fellow creatures marched toward extinction.Scientists continue to study the platypus, Moyal writes in closing, for its remarkable traits, including a seeming sixth sense that helps it locate its prey in the underwater darkness. Her graceful book, shedding new light on the history of biology, ought to earn Ornithorhynchus anatinus many new admirers. --Gregory McNamee

The humble platypus, which few have seen in the wild, created more biological debate in the 19th century than any other animal. In the 20th century, observations led to startling new findings about how the platypus reflects advanced evolutionary development.

When I went to Australia, the platypus was on my most-hoped-to-see list. Fortunately, there was a nice habitat in the Sydney zoo that helped me to learn more about them. The platypus uses burrows as its land home, but spends a lot of time in the water. The platypus can consume half its weight a day in live food. To locate that much food, it relies on an advanced electrolocation method involving its duck-like bill. This method is more effective than the sonar-like methods used by other animals.

Well, what is a platypus? First, you notice the duck-like bill. Perhaps a bird? Second, you notice the fur. Perhaps a mammal? Third, you see the webbed feet. Back to bird? Fourth, close examination shows that the platypus has mammary glands. Mammal? Fifth, the platypus lays eggs that are like those of reptiles. Reptile?

These days, the view is that the platypus is a mammal that lays eggs, along with the echidna. But both animals confounded 19th century naturalists before Darwin when Divine Creation was the dominant theory of evolution. Elaborate classification schemes had been developed that traced everything into one neat family or another. The platypus did not fit.

The first specimens were sent back pickled in alcohol to England and later to France, where dissection sparked a continuing debate about whether or not the platypus had mammary glands and whether or not their young could suckle. How the young were born was a complete mystery.

The mystery could have been solved much sooner, but Europeans chose to ignore what Aborigines and Australians told them about the platypus. So European naturalists came and slaughtered thousands, looking for pregnant and ovulating female platypuses.

Attempts to transport platypuses live failed for a long time, as did attempts to maintain them in captivity.

Eventually, observations by European naturalists established the truth. By the time that Darwin wrote The Origin of Species, the platypus had become one of his greatest examples of natural selection. The platypus had kept some reptile-like features while having evolved into a mammal. Little did he know that the bill's sensors would become the strongest evidence for his argument.

The book is well illustrated with many drawings and a few photographs that provide helpful perspective on this little-known creature.

Ms. Moyal does a fine job of giving us a Down Under view of all this. She combines solid science, explained simply, with a subtle wit about the false speculations and plodding methods of pompous, well-respected scientists. You will enjoy what she has to say.

After you finish this fine book, I suggest that you think about where the evidence around you contradicts what you have been told. For example, it is argued that education is very essential for children. What are the things that children learn to do outside of school (like walk, talk, ride a bicycle, develop a moral sense, and sometimes to read) compared to what they learn in school (like sometimes to read, how to use maps, calculate geometry, and do art projects)? What are the implications for how children and adults could learn more?

Look for better examples and answers!
