Fossils are important because they show what life used to be like back then. Natural selection is when one animal has the same bone structure as its ancestor. One example of natural selection is the chicken and The mighty T.rex. These two animals have similar bone structures and walk pretty much the same. In fact, if we end up making dinosaurs, scientists are gonna use some bone matter and genes from chickens!

(In kid words, change this and make it a bit shorter )

Fossils are important because they tell us about how animals used to live. Natural selection is when animals have similar bone structures as their ancestors. For example, chickens and T.rexes have similar bones and walk in a similar way. Scientists might even use chicken bones and genes to make dinosaurs in the future!
