On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which
helped him to develop his theory of natural selection. It is believed that all of these species had one common ancestor and, over
time, evolved into different species. After the burst of speciation in the Galapagos, a total of 14 species would exist: three species
of ground-dwelling seed-eaters; three others living on cactustes and eating seeds; one living in trees and eating seeds; and 7
species of tree-dwelling insect-eaters. The finches varied mainly in the size and shape of their beaks. What characteristic of the
different islands most likely "selected" the most fit on each island?

A)climate

B)predators

C)competition

D)food sources

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
