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?

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
