Stanford Medicine-led research published in Nature Neuroscience concludes the human brain is two distinct organs that evolved independently over hundreds of millions of years.
The finding overturns the long-held model in which a single early progenitor cell gives rise to the entire brain.
The forebrain handles language, consciousness and abstract reasoning, while the hindbrain governs breathing, sleep, heartbeat and hunger.
Senior author Kyle Loh said the brain's front and back arise from different progenitor cells; Carolyn Dundes and Rayyan Jokhai are co-first authors.

A study described by 404 Media argues early tetrapods lacked a tadpole-like larval stage.
Researchers examined rare hatchling fossils from the fin-to-limb transition, including specimens from Mazon Creek.
The fossils reportedly show no evidence of the external-gill-style metamorphic phase long assumed in textbook accounts.
If confirmed, the finding would reshape how scientists interpret the developmental origins of land vertebrates.

Researchers altered one DNA base in female mouse embryos and observed development of male reproductive organs.
The result highlights how powerful specific regulatory DNA sites can be during embryonic development.
The study reinforces that very small genomic changes can produce major biological effects.
