Although in my opinion – once a geek, always a geek. 😉 Thank you for the clear and concise, open source (for personal use) material. I have heard social scientists say that only mammals have a vagus nerve (which may influence empathy) – however I was given to understand that reptiles and birds have one as well, but it is labelled differently – the pneumogastric nerve? A chart for that as such would also be helpful. Cheers!
