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

Homework for Wednesday
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
Homework for today
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
New material
Galápagos islands – off the coast of South America Why unique? Each island held different species of land organisms.
New material
Evolution: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
New material
Biological Diversity: 1. Species vary Globally Rheas only live in South America and
Ostriches only live in Africa
New material
Biological Diversity: 1. Species vary Globally Or Zebras & horses
New material
Biological Diversity: 2. Species vary locally For example – Foxes (Darwin observed 2
different species of Rheas – we’ll look at foxes)
New material
Biological Diversity: Finally, Species vary over time Fossils
New material
Evolution:New material
Darwin wondered how so many species could be so far apart, but yet be so similar.
Remember Pangaea? The super-continent
New material
Pangaea
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.
New material
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?
