Charles Darwin, the naturalist, geologist, and leading contributor to the fundamental principles of Evolution, comes alive through synthetic interview technology. Duquesne University biology professor John Pollock collaborated with Carnegie Mellon University's Entertainment Technology Center (creator of the Synthetic Interview technology) to develop an interactive experience in which users to select from a list of questions to ask the virtual Darwin, portrayed by Pittsburgh actor and Carnegie Mellon drama alumnus Randy Kovitz. Questions cover Darwin's adventures, the principles of evolution, the public response to his discovery, his childhood, personal quirks and a number of other topics. More than a dozen modern-day biologists, religious authorities, an ACLU lawyer and other experts provide modern commentary and answer questions beyond Darwin's 19th century knowledge. Questions to be answered by Darwin have been drawn from more than 1,000 interviews with K-12 students and adults that were distilled into the 199 most frequently asked questions. Answers to these questions, compiled by Dr. David Lampe, are in Darwin’s own words; drawn from a considerable body of Darwin’s writings, including his notes, books, autobiography, and the thousands of Darwin’s personal letters available through the Darwin Correspondence Project. Principal Funding from the National Institutes of Health/Science Education Partnership Awards (SEPA) and the John Templeton Foundation.

Follow Charles Darwin on his epic voyage aboard the HMS Beagle on its five year journey of exploration and discovery. Charles Darwin sailed from Plymouth, England in 1831. The ship was equipped with scientific instruments for observation and measurement. On this journey Darwin kept copious notes and collected samples of plants, animals, rocks and fossils. As a naturalist he sought to explain the great diversity of life that he found. His research lead him to a comprehensive theory that would become the foundation of modern biology. Learn about the HMS Beagle, a British Royal Navy vessel, gained renown as the ship that carried Charles Darwin on his historic voyage around the world from 1831 to 1836. Designed initially for surveying and charting, the Beagle became an emblem of scientific exploration due to Darwin's transformative journey aboard. Setting sail from England, the ship traversed oceans and continents, allowing Darwin to collect an extensive array of specimens and observations that would later form the basis of his groundbreaking theory of evolution by natural selection. The Beagle's legacy extends far beyond its physical existence, as it represents the intersection of maritime adventure and scientific inquiry that forever altered our understanding of the natural world. Use this app to trace the voyage of the HMS Beagle and learn about Darwin's important discoveries. The app includes maps, diagrams and text to help students learn about the science of evolution. A quiz helps learners measure how well they understand key concepts.
