It is possible for a bacteria to evolve to release neurotransmitters etc.
There is a nervous system in the digestive system that is connected to the brain.
Therefore it is possible for a bacteria to evolve to influence the brain.
If it was possible for a bacteria to evolve to control their host then they would do so.
Therefore, they have done so.
- dTal 4y agoNo doubt this is a reasonable inference chain that was dreamed up many decades ago. But science doesn't stop at inference chains. Now, armed with this hypothesis, we have to go and actually look. Which bacteria? How do they influence the brain? What evolutionary pressures exactly? Reading the article, it looks like we have answers to many of these questions.
