The study examines the evolution of gene regulation in the development of the cerebellum in mammals using AI models.[3] The researchers analyzed cis-regulatory elements that control gene activity in the brain during ontogeny.[2] The findings show the conservation of these regulatory codes across mammalian species.[2] The research covers a period of over half a billion years of evolution.[2] The data is available in the heiDATA repository.[4] The study was published in the journal Science, Volume 391, Number 6784, January 2026.[1]
