Peter Grant’s Conclusions
nPeter Grant concluded:
nNatural selection can produce changes in beaks; this could also explain the origin of species among Darwin’s finches
nIt would require 20 such selection events to transform one species into another; with one drought each 10 years, this would take only 200 years
nBUT:
nChromosome studies show no differences among the finches
nNo natural selection in the wild has been observed
nFinches are still finches today!
