Around two million years ago, a group of birds from South America flew 600 miles west to make their home on the Galápagos Islands.
They belonged to a single species, but by the time Charles Darwin arrived in the Galápagos in the 1830s he found nearly 10 different species, with beaks of various shapes and sizes.
He deduced that the birds, now known as Darwin’s finches, developed these differences to keep from competing for the same food: pointy beaks were better for catching insects, broad beaks were handy for cracking seeds.
