Using giraffes and finches Charles Darwin to explain evolution and natural selection?
Question is in the title Thanks =]
He used to show finches speciation. There were several species of finches on the Galapagos Islands, which were very similar, but had distinct peaks. The different peaks were developed to handle different foods. It was suggested that an ancestral species arrived on the island long before, and radiated in multiple species.

The neck a little longer, would have the advantage and would pass on that trait. For many generations of necks get longer and longer. http://books.google.com/books?id=QrcRAAAAYAAJ&pg=PA304&lpg=PA304&dq = 22origin% + of +% 22 + species of giraffe & source = bl & ots = od0UUU2GKU & sig = 9z1IWyjM-RkjezG1VVDudQdZ3KM & hl = en & ei = fbXKSqTyDJLKsQOotK2iBQ & sa = X & oi = book_result & ct = result & resnum = 6 # v = OnePage & q = & f = false
