Book excerpt: This collection of short stories focuses on the Scottish civil war of 1644-45, in which the Marquis of Montrose led his royalist forces in a series of stunning victories against the odds before his final defeat at Philiphaugh. Each of Hogg's five tales centres on one of the five major battles of Montrose's brilliant but ultimately futile campaign. Each tale is utterly different from the others in genre and tone, but taken together they build up a composite picture of what it was like to experience the 'anarchy and confusion' of the time at first hand.

Available in PDF, EPUB and Kindle. Book excerpt: “Ontogeny recapitulates phylogeny” was Haeckel’s answer—the wrong one—to the most vexing question of nineteenth-century biology: what is the relationship between individual development (ontogeny) and the evolution of species and lineages (phylogeny)? In this, the first major book on the subject in fifty years, Stephen Jay Gould documents the history of the idea of recapitulation from its first appearance among the pre-Socratics to its fall in the early twentieth century. Mr. Gould explores recapitulation as an idea that intrigued politicians and theologians as well as scientists. He shows that Haeckel’s hypothesis—that human fetuses with gill slits are, literally, tiny fish, exact replicas of their water-breathing ancestors—had an influence that extended beyond biology into education, criminology, psychoanalysis (Freud and Jung were devout recapitulationists), and racism. The theory of recapitulation, Gould argues, finally collapsed not from the weight of contrary data, but because the rise of Mendelian genetics rendered it untenable. Turning to modern concepts, Gould demonstrates that, even though the whole subject of parallels between ontogeny and phylogeny fell into disrepute, it is still one of the great themes of evolutionary biology. Heterochrony—changes in developmental timing, producing parallels between ontogeny and phylogeny—is shown to be crucial to an understanding of gene regulation, the key to any rapprochement between molecular and evolutionary biology. Gould argues that the primary evolutionary value of heterochrony may lie in immediate ecological advantages for slow or rapid maturation, rather than in long-term changes of form, as all previous theories proclaimed. Neoteny—the opposite of recapitulation—is shown to be the most important determinant of human evolution. We have evolved by retaining the juvenile characters of our ancestors and have achieved both behavioral flexibility and our characteristic morphology thereby (large brains by prolonged retention of rapid fetal growth rates, for example). Gould concludes that “there may be nothing new under the sun, but permutation of the old within complex systems can do wonders. As biologists, we deal directly with the kind of material complexity that confers an unbounded potential upon simple, continuous changes in underlying processes. This is the chief joy of our science.”

Available in PDF, EPUB and Kindle. Book excerpt: Prior to the First World War, more people learned of evolutionary theory from the voluminous writings of Charles Darwin’s foremost champion in Germany, Ernst Haeckel (1834–1919), than from any other source, including the writings of Darwin himself. But, with detractors ranging from paleontologist Stephen Jay Gould to modern-day creationists and advocates of intelligent design, Haeckel is better known as a divisive figure than as a pioneering biologist. Robert J. Richards’s intellectual biography rehabilitates Haeckel, providing the most accurate measure of his science and art yet written, as well as a moving account of Haeckel’s eventful life.

Available in PDF, EPUB and Kindle. Book excerpt: Fritz Müller (1821-1897), though not as well known as his colleague Charles Darwin, belongs in the cohort of great nineteenth-century naturalists. Recovering Müller's legacy, David A. West describes the close intellectual kinship between Müller and Darwin and details a lively correspondence that spanned seventeen years. The two scientists, despite living on separate continents, often discussed new research topics and exchanged groundbreaking ideas that unequivocally moved the field of evolutionary biology forward. Müller was unique among naturalists testing Darwin's theory of natural selection because he investigated an enormous diversity of plants and animals, corresponded with prominent scientists, and published important articles in Germany, England, the United States, and Brazil. Darwin frequently praised Müller's powers of observation and interpretation, counting him among those scientists whose opinions he valued most. Despite the importance and scope of his work, however, Müller is known for relatively few of his discoveries. West remedies this oversight, chronicling the life and work of this remarkable and overlooked man of science.
