Comment on Revenge of the lizard brainComments−guard-of-terra12yHow can you have a lizard brain when lizards are an unrelated evolutionary branch? It should be a frog brain perhaps.−biggfootOP12yWell a reptilian brain is what he means :) Aren't reptiles common ancestors?−guard-of-terra12yThey 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.−biggfootOP12yHmm. Interesting. So there is absolutely no basis to a reptilian brain component thingie?−guard-of-terra12yThere might or might not be - we still have some our distant evolutionary ancestors; but the nice name for it ("lizard brain") is false.

Well a reptilian brain is what he means :) Aren't reptiles common ancestors?
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.
