Grant’s Later Experiments
nWhen the rains returned:
nIncrease in finch population; and the average beak size returned back to its previous size
nOscillating selection cannot produce any net change in Darwin’s finches
nSeveral species of finches appear to be merging into one
nThe finches seem to be oscillating between diverging and merging
nPerhaps there aren’t that many different species after all!
