They absolutely aren't! Mammals are Synapsids, reptiles and birds are Sauropsida. They branched before most of brain development in both groups took place and since then we don't share ancestors.

There might or might not be - we still have some our distant evolutionary ancestors; but the nice name for it ("lizard brain") is false.
