Summary:Inspired by Stephen J. Gould’s study of Samuel Morton in The Mismeasure of Man, Christa Kuljian’s Darwin’s Hunch traces the story of the search for human origins while apartheid was taking hold of South Africa in the mid 20th century. Following the work of Charles Darwin, biologists and anthropologists of the 19th and 20th centuries were captivated by comparative anatomy, human classification, and the origins of mankind. Kuljian begins her book with the very origin of racialized thought in science: the distinction between monogenism and polygenism. These two schools of thought in the 18th and 19th centuries sought to explain the existence of human difference; the former arguing that all races stemmed from a single ancestor and the latter arguing that different races emanated from different species. Physicians and scientists were at the center of this discourse, creating names for different racial categories while debating whether races were different species in and of themselves. Eventually, well-known physicians and anthropologists created tools to measure anatomical differences between racial groups. Kuljian centers her book on the studies of the physicians and scientists who contributed to academic discourse, including Johann Friedrich Blumenbach, Robert Bloom, Raymond Dart, Hertha DeVilliers, and Phillip Tobias among others.
Summary:Most students of biology are well aware of our humble beginnings as puny, single-celled lifeforms. The mechanism of our remarkable transformation was famously described by Charles Darwin in his groundbreaking text On the Origin of Species, published in 1859. In many respects, Darwin’s magnum opus was just the opening chapter of a much broader discussion of how we humans have taken our current form. Darwin elucidated only a general process of adaptation and evolution in the face of environmental pressures. He left his successors with the more onerous task of applying this rule to the tortuous history of human evolution.
“the history of living organisms has been shaped at every turn by earth’s vicissitudes, because every geologic upheaval, by causing profound changes in the distribution of land and sea, has had profound effects on the climates of both, and hence of the patterns of life in both” (pp. 9).By the final chapter, “Consciousness”, he has begun to ponder questions of metacognition and learning. He marvels at how our complex nervous system has allowed classical pianists to balance the rigidity required for technical prowess, and the fluidity required for creativity. This is not a textbook about our kidneys. From Fish to Philosopher is a story of mankind’s genesis, told through the existential musings of a physiologist who left no stone unturned.
