Presentation Transcript

  1. Do now: • Why is the interior of Australia a desert? • Outer Eastern land has mountains which stops the rain from coming inland.

  2. Homework for Wednesday • This stuff below: • For next class: (Wednesday) – Read pages 454- 457. • 1.) Summarize the reading in your notebook (it will be checked). • 2.) Define the following terms: • Uniformitarianism (not in bold print) • Jean-Baptiste Lamarck(not in bold print) • John Malthus (not in bold print) • Artificial Selection (not in bold print) • Research paper due May 18th. Bring in your work to class so we can cover any questions.

  3. Homework for today • This stuff below: • For next class: (today) – Read pages 450 – 453. • 1. Summarize the reading in your notebook (it will be checked). • Define the following terms: • Evolution • Charles Darwin (not in bold print) • Fossils • Galápagos species (not in bold print) • Research paper due May 18th

  4. New material • Who was Charles Darwin? • Developed the theory of Evolution, natural selection (also lead to artificial selection), Survival of the fittest • Where did he travel and why is this significant? • Galápagos islands

  5. New material • Galápagos islands – off the coast of South America • Why unique? • Each island held different species of land organisms.

  6. New material • Evolution:

  7. New material • One of his most important, but often over looked discoveries dealt with diversity. • Biological Diversity: • 1. Species vary Globally • Explain • 2. Species vary locally • Explain • 3. Species vary over time • Give an example

  8. New material • Biological Diversity: • 1. Species vary Globally • Rheas only live in South America and Ostriches only live in Africa

  9. New material • Biological Diversity: • 1. Species vary Globally • Or Zebras & horses

  10. New material • Biological Diversity: • 2. Species vary locally • For example – Foxes (Darwin observed 2 different species of Rheas – we’ll look at foxes)

  11. New material • Biological Diversity: • Finally, Species vary over time • Fossils

  12. New material • Evolution:

  13. New material • Darwin wondered how so many species could be so far apart, but yet be so similar. • Remember Pangaea? The super-continent

  14. Pangaea

  15. New material • Darwin never considered Pangaea, but it would make sense if the world were so large and then split causing organism to evolve differently. A process known as Speciation.

  16. Reminder • Bring in your research project material especially if you are struggling to put it all together. • The project: • What is the disease or condition – explain in written portion and explain on the board. • Why is it important? • How does it impact? • How do these people develop the condition or in the case of the twins, how do they each develop? • How does it impact their day to day life?
