Why does DNA have Thymine while RNA has Uracil?

The only difference between the two bases is a methyl group instead of a hydrogen, and those two aren't the part of the base that bond to the pentose, and also don't participate in hydrogen-bonding with adenine, so why do we have a different base for each of the nucleic acids?
