Abstract
A new study has found that lampreys, a type of jawless fish, have nerve cells responsible for the "fight or flight" stress response, similar to humans. This challenges the previous belief that this part of the nervous system only emerged in jawed vertebrates. The researchers used a technique to tag and light up specific RNA molecules in lamprey embryos, revealing clusters of cells associated with the sympathetic nerve cells found in jawed vertebrates. The findings suggest that the sympathetic nervous system has been around since before lampreys diverged from the main vertebrate line, about half a billion years ago. [Extracted from the article]
