Part I-THE ORIGINS OF SPECIES BARRIERS: 2 The Genetic Basis of Reproductive Isolation: Insights from Drosophila-H. The papers are organized into sections covering the origins of species barriers, the processes of species divergence, the nature of species, the meaning of “species,” and genomic approaches for understanding diversity and speciation.ġ Introductory Essay: Systematics and the Future of Biology-EDWARD O. Wilson, this book includes the 16 papers presented by distinguished evolutionists at the colloquium. In addition to a preceding essay by Edward O. Mayr formulated the transition from Linnaeus’s static species concept to the dynamic species concept of the modern theory of evolution and emphasized the species as a community of populations, the role of reproductive isolation, and the ecological interactions between species. In 1942, Ernst Mayr, one of the twentieth century’s greatest scientists, published Systematics and the Origin of Species, a seminal book of the modern theory of evolution, where he advanced the significance of population variation in the understanding of evolutionary process and the origin of new species. In December 2004, the National Academy of Sciences sponsored a colloquium on “Systematics and the Origin of Species” to celebrate Ernst Mayr’s 100th anniversary and to explore current knowledge concerning the origin of species.
For those interested in curling up and reading at a more reasonable type size, we’ve also created a book. The printed poster allows you to see the patterns where edits and additions were made and-for those with good vision-you can read all 190,000 words on one page. The original interactive version was built in tandem with exploratory and teaching tools, enabling users to see changes at both the macro level, and word-by-word. By color-coding each word of Darwin's final text by the edition in which it first appeared, our latest book and poster of his work trace his thoughts and revisions, demonstrating how scientific theories undergo adaptation before their widespread acceptance. In fact, it wasn’t until his fifth edition that he introduced the concept of “survival of the fittest,” a phrase that actually came from philosopher Herbert Spencer. As a result, his final work reads as a composite, containing more than a decade’s worth of shifting approaches to his theory of evolution.
