I think it's easy to underestimate how different our brains are relative to different classes of animals, and there is a lot of convergent evolution going on.

I think it's easy to underestimate how different our brains are relative to different classes of animals, and there is a lot of convergent evolution going on. For example, even low level auditory perception, such as how the brain evolved to localize sound directions, evolved independently in mammals and birds: https://journals.physiology.org/doi/full/10.1152/physrev.00026.2009 https://journals.physiology.org/doi/full/10.1152/physrev.000... (this is because their common ancestor didn't have a tympanic ear). So the Triune brain really isn't the best model for explaining what is going on in the brain. Models such as reinforcement learning don't fully explain what is going on in the brain either, but I think explanations such as how dopamine flooding the reward system can mess with predicted rewards and contribute to addiction, etc. are more useful.
