Several steps led to the evolution of 13 different finch species on the Galápagos Islands. Rearrange the steps that led to the many species of Darwin’s finches into the correct order. Place the first step at the top and the final step at the bottom.

Founder finches arrive on one of the Galápagos Islands.

Changes in gene pools occurred as the bird populations adapted to the specific environment of each island.

Differences in beak size and mating behavior probably led to reproductive isolation as some birds crossed back from the second island to the first island.

A few birds crossed to another island and the two bird populations were now geographically isolated.

Over time, as these two species lived together on the same island, they evolved in a way that increased the differences between them.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
