rnst Mayr was born in Kempten, Germany, on July 5, 1904, making him, at age 95, the grand old man of evolutionary biology, one of the primary architects of the modem synthesis of genetic and evolutionary theory, and arguably one of the most influential scientists of the 20th century. His career interests have spanned a remarkable five different fields, including: (1) ornithology, (2) systematics, (3) zoogeography, (4) evolutionary theory, and (5) philosophy and history of science. Such broad research interests grew (...) from his education at a German Gymnasium (the equivalent of American high school, but at that time considerably more demanding), followed by a Candidacy in Medicine at the University of Greifswald in 1925 and a Ph.D. in zoology at the University of Berlin in 1926.

ve r since the appearance of Ontogeny and Phylogeny a decade ago, Stephen Jay Gould has continued to delight and inform a wide spectrum of readers and, in doing so, to defy C.P. Snow's lament about the "two cultures" of the sciences and the humanities. Gould's monthly column in Natural History magazine, published under the heading "This View of Life," has led to a series of highly praised volumes of essays—Ever Since Darwin (1977), The Panda's Thumb (1980), Hen's Teeth and (...) Horse's Toes (1983), and most recently The Flamingo's Smile (1985). In addition, Gould's The Mismeasure of Man (1981), which won the National Book Critics' Circle Award, analyzed the questionable character of intelligence testing and emphasized the many personal and cultural biases that have led researchers astray in this field. Given the sheer amount of Gould's publications, which include numerous scientific publications as well, Gould's readers have been kept busy indeed absorbing his prodigious output. (shrink)

During his historic Galápagos visit in 1835, Darwin spent nine days making scientific observations and collecting specimens on Santiago (James Island). In the course of this visit, Darwin ascended twice to the Santiago highlands. There, near springs located close to the island's summit, he conducted his most detailed observations of Galapagos tortoises. The precise location of these springs, which has not previously been established, is here identified using Darwin's own writings, satellite maps, and GPS technology. Photographic evidence from excursions to (...) the areas where Darwin climbed, including repeat photography over a period of four decades, offers striking evidence of the deleterious impact of feral mammals introduced after Darwin's visit. Exploring the impact that Darwin's Santiago visit had on his thinking - especially focusing on his activities in the highlands - raises intriguing questions about the depth of his understanding of the evolutionary evidence he encountered while in the Galápagos. These questions and related insights provide further evidence concerning the timing of Darwin's conversion to the theory of evolution, which, despite recent claims to the contrary, occurred only after his return to England.
