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.
- biggfoot 13y agoHmm. Interesting. So there is absolutely no basis to a reptilian brain component thingie?
- guard-of-terra 13y agoThere might or might not be - we still have some our distant evolutionary ancestors; but the nice name for it ("lizard brain") is false.
