What a world!
After learning in the last few years about what’s living in my digestive system, now I’m learning about the environment in my respiratory system.
It’s all very “alien”.
did the article talked about cells that could turn light to productive use. That these cells lived in symbiotic relationship with things like coral and jellyfish. I didnt read anything about these cells living in the lungs. but maybe these cells are not healthy additions to the lungs. can you cite the passage that showed that this genus can live in human lungs?
Its not just that foreign bacteria live in the guts—they outnumber human dna. Much of our emotional lives come from that bacteria too—as a function of the food we eat or don’t eat. Further all early life had a nervous system that was primarily involved with digestion. So there is a huge part of our nervous system — of which we are unaware that is devoted to digestion. Indeed scientists find that the same bacteria that live in the gut also inhabit the brains.
A lot of stuff happened in the early part of life on earth. For example cell in our bodies have two sets of genetics. One of the cell and one for the mitochondria. It is believed that the mitochondria fused with these cells in all animals a couple hundred years ago. According to genome.gov
Mitochondrial DNA, unlike nuclear DNA, is inherited from the mother, while nuclear DNA is inherited from both parents. So this is very helpful sometimes in determining how a person has a certain disorder in the family. Sometimes a disease will be inherited through the mother’s line, as opposed to both parents. https://www.genome.gov/genetics-glossary/Mitochondrial-DNA#:~:text=Mitochondrial%20DNA%2C%20unlike%20nuclear%20DNA,as%20opposed%20to%20both%20parents.
