Where did the new beak shapes come from so quickly in such a small population? I think your confusion comes from thinking that 100 birds or so is such a small population. There may be only 100 birds but each bird was unique. Since it was a small population there was probably plenty of food so even a poor eater could survive and have baby birds. The baby birds had a variety of beak shapes. Some ate better than others and produced more baby birds the next generation. After a while there would be a lot of finches and they would predominately be the ones who ate better. Once there were more finches than food there would be a competition and the ones with the less effective beaks wouldn't get much to eat at all and wouldn't have any baby birds. I don't know if that's just how it happened. That is what is known in evolution circles as a "Just So Story" (http://www.gutenberg.org/files/2781/2781-h/2781-h.htm). But that is what I think is a likely way it happened.
