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. By matching together the strands of DNA from these fossils can help scientists match together the strands of DNA sequences For example the gene for a protein found in a horse will overlap in sequence fairly well with the protein gene from a cow but will not match very well with a worm.
