  1. Unit 9: Evolution Lesson 1: An Introduction to Charles Darwin and the Nature of Science

  2. Evolution Project • New randomized groups • 4th quarter grade: Daily class work/homework collected in a final portfolio • Final Exam grade: Five “In Depth Investigations” • Graded according to a rubric/ average grade will be final grade. • Ends May 28th (We will not observe review days.) • Consequences of not fulfilling individual work requirements.

  3. “A scientist, however, gifted, can be compared with a fly crawling on the inside wall of a cathedral; if it could draw what it sees, the fly’s picture of the cathedral would be as crude as early maps of the world; if it could voice its speculations about the size, appearance, and purpose of the cathedral, the fly’s opinions would be received even more guardedly.” -- Frederick Aicken, The Nature of Science , pp.29-30

  4. Evolution As An Idea“ If I were to give an award for the single best idea anyone has ever had, I’d give it to Darwin, ahead of Newton and Einstein and everyone else. In a single stroke, the idea of evolution by natural selection unifies the realm of life, meaning and purpose with the realm of space and time, cause and effect, mechanism, and physical law. But it is not just a wonderful idea. It is a dangerous idea.” Daniel Dennet

  5. Evolution as an Idea “Evolution is one of the most powerful ideas ever to emerge from science. It is the very foundation of biology and the key to understanding our own human origins. The mechanism of evolution helps determine who lives, who dies, and who gets the opportunity to pass on traits to the next generation. At the same time, evolution ranks as one of the most widely misunderstood scientific principles in America today.” Richard Hutton, Executive Producer, Evolution WGBH Jody Patton, Executive in Charge, Clear Blue Sky productions

  6. Darwin’s Voyage of Discovery • Take the Pre-Test • Homework • Go to the following link: http://www.pbs.org/wgbh/evolution/educators/lessons/lesson2/act1.html • Complete the directions in Lesson 2 Activity 1. This will require you to… • Read the activity • Print the world map • Read the excerpts of Darwin’s Voyage • Write a paragraph that answers the question: Who was Charles Darwin?

  7. Darwin and the Galapagos When your group finishes answering the questions for In Depth Investigation #1, discuss the following: • How did the Galapagos Islands get there? • How did the first plants get there? • How did the first animals get there? • What is ecological succession?

  8. Galapagos Islands

  9. Galapagos Islands

  10. Ecological Succession • process in which communities of plants and animal species in a particular area are replaced over time by a series of different and often more complex communities. • Two stages • Primary succession • Secondary succession

  11. Primary Succession succession in a bare area (no mature soil) that has never been occupied before

  12. Secondary Succession succession in an area in which natural vegetation has been removed or destroyed but the soil remains

  13. Ecological Succession
