Hi everyone, I'm currently reading Richard Dawkins' book The Blind Watchmaker and there is one part that had me really fascinated, but wasn't really explored in detail that much. On page 249 he writes: I know that some organisms (like anglerfish that use bio-luminescent bacteria, for example) can use other organisms in their own biochemistry, but I wasn't aware that a "cross infection", as he puts it, could occur. Can anyone point me in the direction of some additional resources that explore this topic in detail? Preferably at the "pop science" level as my background is in math and physics, not biology! Thanks!
