IDEAS THAT SHAPED DARWIN’S THINKING Big Q: What was Charles Darwin’s contribution to science? Big Q: What three patterns of biodiversity did Darwin note? Big Q: How did Lamarck propose that species evolve?

ENGAGE - IT HAPPENED IN HAWAII Identify an organism that is local to your area. Describe the organism and describe how it is uniquely adapted to your local environment. FOLLOW-UP QUESTION: The Galapagos Islands are located on the equator and therefore have a subtropical climate. Predict whether your particular organism would survive or how it might adapt if it were in an environment more like the Galapagos Islands.

EXPLAIN - CHARLES DARWIN ➤ Charles Darwin - Journeyed the world in the 1800’s on the HMS Beagle to find evidence to support evolution ➤ Evolution - how modern organisms changed over long periods of time through descent from common ancestors Explain how the ideas of a changing Earth and evolving life forms might be related

EXPLAIN- DARWIN’S JOURNEY Rheas ➤ Observations aboard the Beagle: ➤ 1. Species vary globally ➤ 2. Species vary locally ➤ 3. Species vary over time Ostriches Emus Why are large flightless birds found in the grassland habitats around the world? Isabela Hood

EXPLAIN- SPECIES VARY OVER TIME ➤ Darwin found records of prior life ➤ Fossils - preserved remains or traces of ancient organisms Glyptodont Armadillo

EXPLAIN - HUTTON AND LYELL ➤ Primitive Earth - the Earth is old and ever changing. At one point the Earth was extremely hot, acidic, and full of poisonous gases ➤ Hutton - acknowledged that the tectonic plates shift and change the geography of Earth ➤ Lyell - functions of the Earth are the same now as they were back in ancient times

EXPLAIN - LAMARCK ➤ Jean Baptiste Lamarck - French scientist who proposed ideas that helped Darwin form theory of evolution ➤ Theories: ➤ 1. Use and Disuse - if you don’t use it, you lose it ➤ 2. Inheritance of Acquired Traits - any traits you acquire in your lifetime can be passed on to your offspring
