This book is the first detailed biography of Ernst Mayr. He was an
'architect' of the Synthetic Theory of Evolution, and the greatest
evolutionary biologist since Charles Darwin, influential historian and
philosopher of biology, outstanding taxonomist and ornithologist, and
naturalist. He is one of the most widely known biologists of the 20th
century. Mayr used the theories of natural selection and population
thinking as theoretical models within the framework of historical
biological studies. He suggested that various competing paradigms may
exist side by side and more or less pronounced 'revolutions' may occur
in different fields from time to time. Mayr was the first to emphasize
the role of biopopulations, thereby pointing out the basic difference
between 'population thinking' and typological essentialism. Population
thinking takes into consideration the uniqueness of each individual and
unlimited variation of populations which may lead to the development of
new species.
