Please Don't Eat the Daisies: The macroevolution of alternate plant defense strategies
We are living in a bacterial world, and it's impacting us more than previously thought
(Phys.org)—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 ...
