How were finches able to survive the environmental changes?
For the finches, body size and the size and shape of their beaks are traits that vary in adapting to environmental niches or changes in those niches. Under these drastically changing conditions, the struggle to survive favored the larger birds with deep, strong beaks for opening the hard seeds.
Why do the finches have different adaptations?
Darwin wondered about the changes in shape of bird beaks from island to island. So-called cactus finches boast longer, more pointed beaks than their relatives the ground finches. Beaks of warbler finches are thinner and more pointed than both. These adaptations make them more fit to survive on available food.
What is an example of how animals were adapted for their specific environments on the Galapagos island?
For example, thick, crushing beaks are good for eating seeds and nuts, and long, probing beaks are adapted to eating insects. The vampire finch, a distinct subspecies of the sharp-beaked ground finch, may take the cake for the most interesting (and macabre) adaption among Darwin’s finches.
