Researchers discovered that transposable elements (TEs) provided more than 20,000 regulatory binding sites that drive neural development. By acting as genomic couriers for transcription factors like Sox2 and Brn2, these "jumping genes" expanded the complexity of the mammalian brain, offering a new two-phase model of how our neural networks evolved.
