Did Darwin see evolution as progressive, directed toward producing ever more advanced forms of life? Most contemporary scholars say no. In this challenge to prevailing views, Robert J. Richards says yes—and argues that current perspectives on Darwin and his theory are both ideologically motivated and scientifically unsound. This provocative new reading of Darwin goes directly to the origins of evolutionary theory. Unlike most contemporary biologists or historians and philosophers of science, Richards holds that Darwin did concern himself with the idea of progress, or telos, as he constructed his theory. Richards maintains that Darwin drew on the traditional embryological meanings of the terms "evolution" and "descent with modification." In the 1600s and 1700s, "evolution" referred to the embryological theory of preformation, the idea that the embryo exists as a miniature adult of its own species that simply grows, or evolves, during gestation. By the early 1800s, however, the idea of preformation had become the concept of evolutionary recapitulation, the idea that during its development an embryo passes through a series of stages, each the adult form of an ancestor species. Richards demonstrates that, for Darwin, embryological recapitulation provided a graphic model of how species evolve. If an embryo could be seen as successively taking the structures and forms of its ancestral species, then one could see the evolution of life itself as a succession of species, each transformed from its ancestor. Richards works with the Origin and other published and archival material to show that these embryological models were much on Darwin's mind as he considered the evidence for descent with modification. Why do so many modern researchers find these embryological roots of Darwin's theory so problematic? Richards argues that the current tendency to see evolution as a process that is not progressive and not teleological imposes perspectives on Darwin that incorrectly deny the clearly progressive heart of his embryological models and his evolutionary theory.

In 1905, eight men from the California Academy of Sciences set sail from San Francisco for a scientific collection expedition in the Galapagos Islands, and by the time they were finished in 1906, they had completed one of the most important expeditions in the history of both evolutionary and conservation science. These scientists collected over 78,000 specimens during their time on the islands, validating the work of Charles Darwin and laying the groundwork for foundational evolution texts like Darwin's Finches. Despite its significance, almost nothing has been written on this voyage, lost amongst discussion of Darwin's trip on the Beagle and the writing of David Lack. In Collecting Evolution, author Matthew James finally tells the story of the 1905 Galapagos expedition. James follows these eight young men aboard the Academy to the Galapagos and back, and reveals the reasons behind the groundbreaking success they had. A current Fellow of the California Academy of Sciences, James uses his access to unpublished writings and photographs to provide unprecedented insight into the expedition. We learn the voyagers' personal stories, and how, for all the scientific progress that was made, just as much intense personal drama unfolded on the trip. This book shares a watershed moment in scientific history, crossed with a maritime adventure. There are four tangential suicides and controversies over credit and fame. Collecting Evolution also explores the personal lives and scientific context that preceded this voyage, including what brought Darwin to the Galapagos on the Beagle voyage seventy years earlier. James discusses how these men thought of themselves as "collectors" before they thought of themselves as scientists, and the implications this had on their approach and their results. In the end, the voyage of the Academy proved to be crucial in the development of evolutionary science as we know it. It is the longest expedition in Galapagos history, and played a critical role in cementing Darwin's legacy. Collecting Evolution brings this extraordinary story of eight scientists and their journey to life.
