Peter and Rosemary Grant have seen evolution happen over the course of just two years. The Grants study the evolution of Darwin’s finches on the Galapagos Islands. Each species eats a different type of food and has unique characteristics developed through evolution.Click to see full answer. Herein, what was the grants Brief goal of their studies?The Grants’ goal was to determine how each of the 14 species of finches evolved from the ancestral one, which likely flew in from the South American mainland.Subsequently, question is, what caused the change in the finches beaks as seen in the Grants study? Darwin hypothesized that the Galapagos finches he observed had descended from a common ancestor. Darwin proposed that natural selection had shaped the beaks of different bird populations as they became adapted to eat different foods. Regarding this, what did the Grants conclude? Peter and Rosemary Grant are distinguished for their remarkable long-term studies demonstrating evolution in action in Galápagos finches. They have demonstrated how very rapid changes in body and beak size in response to changes in the food supply are driven by natural selection.What happened to the finches at Daphne Major?A severe drought in 1977 killed off many of Daphne’s finches, setting the stage for the Grants’ first major discovery. During the dry spell, large seeds became more plentiful than small ones. Birds with bigger beaks were more successful at cracking the large seeds.
