Fossils give Scientists look into past life. A dinosaur that mixes together a reptile and a bird helps scientists understand present day reptiles & birds. Animal Ancestry helps Scientists discover what ancestors of present day animals are. example: a dinosaur and an alligator. DNA sequences help with this.
