Was the layered cortex really unique to amniotes? Salamanders, our anamniote cousins, suggest otherwise.
In a new preprint from Maria Antonietta Tosches’ lab (first author Astrid Deryckere), we show that salamanders share core developmental logic with mammals — but with an ancestral outside-in sequence.
Clonal lineage tracing in salamanders reveals that both superficial and deep-layer neurons arise from the same multipotent radial glia.
Glad to have contributed to this work.
