Two biologists tackle the unresolved question in the field of evolution: how have living organisms on Earth developed with such variety and complexity? In the 150 years since Darwin, the field of evolutionary biology has left a glaring gap in understanding how animals developed their astounding variety and complexity. The standard answer has been that small genetic mutations accumulate over time to produce wondrous innovations such as eyes and wings. Drawing on cutting-edge research across the spectrum of modern biology, Marc Kirschner and John Gerhart demonstrate how this stock answer is woefully inadequate. Rather they offer an original solution to the longstanding puzzle of how small rand...
Gerhart and Kirschner aim to explain the origins of phenotypic variation and evolutionary adaptation from within eukaryotic cell biological and developmental processes. Their examples are drawn from paleontology, developmental and cell biology.

This book applies new scientific research in the fields of biology and genetics to an empirical study of the Greco-Roman civilizations and the European Renaissance. These two periods were remarkable in part because of the dominance of empathy and humanism in the philosophical thought of each era. Both periods were preceded by the influx of many populations and genetic lines, a circumstance this book treats as not coincidental but probably causative. The author cites the expression of new genetic combinations in these periods as evidence that genetic evolution can play a large part in the development of new philosophical concepts, as manifested in these two periods. The author explains that humanistic traits seem to rise and fall in lockstep throughout human history, directly or indirectly correlating with changing genetic underpinnings.
In Reflections on Leadership fifteen prominent leadership scholars pay tribute to James MacGregor Burns's book, Leadership, a classic in the field of leadership studies. The contributors address the puzzles and anomalies in his work, such as: the place of values in leadership; leadership as a casual factor in change; levels of analysis; interdisciplinary approaches to the study of leadership; the distance of his theory from everyday experience; the absence of gender and race, and more.
This book integrates the work of philosophers of science seeking to make sense of genetics with an accessible introduction to the science.
Is Darwinian evolution really the most successful scientific theory ever proposed—or even the best idea anyone has ever had, as Daniel Dennett once put it? The Mystery of Evolutionary Mechanisms provides a comprehensive critical reading of the literature of evolutionary biology from Darwin to Dobzhansky to Dawkins, revealing this popular account of evolution to be a grand narrative of Darwinian triumph that greatly overstates the empirical validity of modern evolutionary theory. The mechanisms driving the evolutionary process truly remain a mystery more than one hundred fifty years after Origin of Species, a fact that can free religion scholars to think in more creative ways about the positive contributions religious reflection might make to our understanding of life’s origin and diversity. The Mystery of Evolutionary Mechanisms calls for an embrace of mystery, understood not as an abdication of the scientific quest for truth but as a courageous and humble acknowledgment of the limits of human reason and an openness to a fundamentally religious orientation toward life.
