Darwin's finches speciation
WebReduced gene flow plays a critical role in speciation. There are three modes of speciation often classified as allopatric, parapatric, and sympatric speciation. A major example of allopatric speciation occurred in the Galapagos finches that Charles Darwin studied. Allopatric speciation is genetic divergence permitted by geographic isolation. WebThis eventual process of speciation by natural selection is illustrated by a sketch drawn by Darwin in his personal notebook nearly 20 years before the Origin of Species was published (Figure 1 ...
