Monday, June 6, 2011 • To understand how Darwin developed his theory of evolution I can: • Level E: state Darwin’s Theory of Evolution • Level D: state Darwin’s Theory of Evolution and describe two observations that lead to his theory • Level C: explain Darwin’s Theory of Evolution and apply it to classification of species “Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science” Charles Darwin (12 February 1809 – 19 April 1882) • Conducted research throughout the world (most specifically in the Galapagos islands off the coast of Ecuador) • After looking at the similarities and differences between various animals around the world he developed a theory on the origin of species • Wrote a book called ‘On the Origin of Species’ Evidence for Evolution • Fossil Record • Variations within and between current species • Looked at how fossils developed and changed over time Main Idea: • Gradual changes in species due to genetic variation leads to the development of new species via Natural Selection • i.e. All species come from the same ancestor species – Including humans TASK: • Use the internet to fill in the glossary like the one posted on the board • Once you have filled out the glossary... Evolution? • The book ends with the following statement: “There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and wonderful have been, and are being, evolved.”
