So I have noticed that most herbs come from the Mediterranean as confirmed by this site and those that do not often come from either actual Mediterranean climates or somewhat arid ones.
So my question is: is there a link between the two? Edgar from Artifexian argues that Mediterranean climates are the best for fertile crescents/the development of agriculture because of the annual drought and the adaptations plants have to develop in response. Is it a similar system in aromatic herbs? Is it a defence mechanism like tobacco evolved nicotine to fight off insects? I just want to know where is the most likely to be home to aromatic herbs on my world and why.
Thanks a lot!
