1. Why is Evolution Important? Lydia A. & Daniela H. Block 2 Unit 7 Project

2. Why is Evolution Important? Understanding evolution represents a huge achievement in science. Successfully explains diversity and has been confirmed multiple times Foundation of modern biology Opened the door for research and techniques

3. How Science Works Observe nature and test questions Ideas accepted or rejected based on evidence Scientific Theory’s – well established ideas Evolution is a theory

4. The Theory of Evolution Has Been Repeatedly Tested and Confirmed Basis of Evolution – Traits pass from parents to children, traits change between some generations New traits that help one survive become more widespread, don’t help become less widespread Natural Selection – Some traits succeed some don’t

5. The Fossil Record Evolution is supported by fossil evidence Younger rocks – Closer to todays life forms Older rocks – Less Similar Fossils repeatedle confirm changes in lifee forms

6. DNA Research Molecular Biology and Genetics further prove evolution DNA passes on traits from parents to children Support findings from other scientific branches

7. Common Ancestry Bones very different but also similar Ancestral species make up todays species Any two living species can be traced back to the same ancestor Adds to the evidence of evolution and natural selection

8. Creationism in the Classroom? Creationism should be added to textbooks along with biological evolution Based on beliefs Argue evolution is faulty because of gaps in fossil records To complex to have randomly been made Creationism not scientific enough

9. Science Vs. Religion Some scientists have had their faith enhanced Some religious people believe in evolution

10. Evolution in Action In China many people were in infected with severe Pneumonia Using DNA microarray scientists found what family of viruses it fell into and began a vaccine within 24 hours Understanding evolutionary origins helps find vaccines to new mutated viruses

11. Tiktaalik Scientific-using principles of evolution, try to determine new fossils Predicted a half land half water creature Found it in Canada, called Tiktaalik Filled another gap in fossil evidence
