Intelligence evolved twice - independently in birds and mammals
Scientists have discovered that intelligence evolved independently in birds and mammals, through different developmental pathways despite ending up with similar functional outcomes. Using RNA sequencing to track neural development, researchers found that while mature circuits look alike across species, they develop from different embryonic regions through different pathways https://www.quantamagazine.org/intelligence-evolved-at-least-twice-in-vertebrate-animals-20250407/
