“…Instead of the prefrontal cortex, birds evolved another region (nidopallium caudolaterale) for cognitive functions. It is believed that this region evolved separately from the mammalian prefrontal cortex as it has a structure different from the prefrontal cortex (Clayton and Emery 2008, 131-132;Güntürkün et al 2024;Güntürkün 2012). Moreover, some corvids have more complex cognitive capacities than some mammals (Clayton and Emery 2008, 130), and this, too, implies convergent evolution.…”
