Finches beak darwin
WebThe diagram below gives a clearer idea of the different beaks that each Darwin Finch species has developed. In fact, today Galapagos Finches can be differentiated not only by beak size and shape, but also by body size, song and feeding behaviour. As such, Darwin Finches are an exceptional example of the process of evolution of species.
