Ethology All books
The first and constant motive of my scientific life has always been the blood, and its formation, diseases and mutations. During the day, I studied corpuscles and serums. In the evening I read or reread poetry. Sometimes I came across blood once again. An intuition, an allusion of a poet came to clarify my clinical or biological reflections of the next day. These kind of exchanges have inspired this book, which constitutes a personal anthology. It is the same blood which runs in the veins of Iphigenis before the planned sacrifice, as wriggles under our gaze using the microscope, and as draws our eyes to the lips it colours The present anthology bears witness to this unity and this diversity of the blood.

The issue of the differences and similarities between humans and their cousins the chimpanzees governs the definition of human identity. How can this difference be explained? By studying the learning process of chimpanzees and comparing it to that of children, Ann and David Premack were gradually able to discover a series of differences, none of which were radical but when put together showed a yawning gap between the two species. The results they obtained enabled them to reconstruct little by little the sum of the differences that make up human identity. Ann and David Premack are specialists in the study of primates.
In this book, the author points out that although human beings are both mammals and primates, they differ in many significant ways from the other mammals and primates. Besides speech, laughter and the ability to use tools, the species Homo sapiens differs from its closest zoological cousins by three additional characteristics, which are less frequently cited because they are found only in the female. These are the female silhouette, hidden strus and the menopause. Rolf Schäppi is a psychiatrist and ethologist.
In this book, the author, an expert in his field, describes the most fascinating stages in the eels biological cycle, its migrations and the modifications it undergoes during its life. Eels interest us not only because of their life and breeding cycles, but also because of the questions they raise concerning our ideas about evolution. Does the notion of adaptation suffice to explain everything the eel has become? Doesnt a living creature maintain a certain amount of independence in relation to the world that surrounds it? Or is the relationship between a living creature and the environment which surrounds it more complex that we have generally realised ?
