I read this title and it made me think of the song "I'm a Barbie Girl, in a Barbie World" lol It's amazing how interdependent we are on the tiniest organisms on this planet, and kinda cool to think that we've got DNA in us that's billions of years old.

We are living in a bacterial world, and it's impacting us more than previously thought

Throughout her career, the famous biologist Lynn Margulis (1938-2011) argued that the world of microorganisms has a much larger impact on the entire biosphere—the world of all living things—than scientists typically recognize. Now a team of scientists from universities around the world has collected and compiled the results of hundreds of studies, most from within the past decade, on animal-bacterial interactions, and have shown that Margulis was right. The combined results suggest that the evidence supporting Margulis' view has reached a tipping point, demanding that scientists reexamine some of the fundamental features of life through the lens of the complex, codependent relationships among bacteria and other very different life forms.
