Question

During the drought of 1977 on the island of Daphne major which of the following answers correctly explains why birds with larger beaks had a competitive advantage over other individuals

Answer 1

Birds with larger beaks had a competitive advantage during the drought of 1977 on the island of Daphne Major because they were able to access and feed on larger seeds that were left behind by smaller-beaked birds who were unable to crack open the tough outer shells of the seeds. This gave the larger-beaked birds a better chance of survival and reproduction, allowing them to pass on their advantageous traits to future generations. Over time, this led to a shift in the average beak size of the bird population on the island, with larger beaks becoming more common.
