How is natural selection, phenotype and genes involved?

Gene pool vs. geneotype vs. phenotype? Darwin's role and finches?

The moths in England and how lead to different phenotypes. How fossils formed. What they tell us and why are there gaps. What else gives evidence of evolution besides fossils and tells us who is related to whom?

Archaeopteryx-why is a good model of a transition between reptiles (Dinosaurs) and birds?

An example of nateral selection in finches:

to start with there were a variation in the species they had different sized beaks. then the finches with the bigger beaks could fit more berry's in their mouth whereas the finches with the smaller beaks couldn't so they died out from starvation. The finches with the bigger beaks survived and bred successfully passing their genes onto their offspring.
