Domanda 14 di 18

In 1981, an immature male finch (Geospiza conirostris) arrived on an island in the Galapagos. This male finch was similar to finches of the species (G. fortis) living on the island. However, G.conirostris was 70% larger than G. fortis and had a distinctly different song. The diagram shows how, after observing further generations, a new species has evolved. The success of the new species is due to its larger bill and body size and its unique song. Which of the following terms is/are illustrated by this information? 1 sympatric speciation 2 reproductive isolation 3 post-zygotic isolation
