A long time ago, a scientist named Charles Darwin sailed to the Galápagos Islands, far out in the Pacific Ocean. There he found small brown birds called finches. They all looked like cousins, but their beaks were different shapes and sizes.
Some finches had big, strong beaks for cracking hard seeds. Others had thin, pointy beaks for picking insects out of cracks. A few even had beaks like tiny tools for pulling grubs out of trees. Each beak was perfect for the food on its own island.
Darwin realised something huge: the birds had changed over many, many years to fit the place where they lived. That idea is called evolution, and it changed how we understand all living things. Darwin later wrote a famous book about it, called On the Origin of Species. Today scientists still visit the Galápagos to watch the finches — and they are still changing, right now, as the islands themselves change.
🤩 Wow fact!
There are about 18 kinds of Darwin's finch, and almost all of them live only on the Galápagos Islands — nowhere else on Earth.
🧠 Quiz time!
What did Darwin notice was different about each kind of finch?
