	Chapter 3 - The Arguments and the Evidence Charles Darwin knew natural selection had to be accompanied by an inheritance system in which blending did not dilute the selected effects. He proposed pangenesis, which turned out to be wrong, in his 1883 book on domestication of plants and animals. Read Chapter XXVII, a "provisional hypothesis" that Darwin had proposed. Visit the The Variation of Animals and Plants Under Domestication Chapter XVII web site.

The brain is an important organ with some very striking relationhips of its structure to animal position in evolution. Find some representatives to animal brains. Do you see similarities, differences? Visit the Comparative Mammalian Brain Collections web site.

Select two or three islands that interest you and read some details of their natural (or at least tourist) appeal. Visit the The Galapagos Islands web site.
