All living things have genes, which are like little sets of blueprints. Genes have information about the color of your eyes, the shape of your nose, and whether you hair is straight or curly. When living things make other living things, they pass copies of these blueprints to the offspring. The copies are mixtures. They’re never exact, never quite perfect. So, the cool thing is that no two sets of blueprints are exactly alike. So each living thing is different from other living things. Scientists know about evolution from fossils. Fossils show how living things used to look millions of years ago. Scientists take information from fossils to see how living things have changed over thousands, hundreds of thousands, and millions of years.
