I want to know the answer to the following question:
What far-reaching result do scientists think has come about from symbiosis with bacteria?
All the background I'm provided with is that "While historically, symbiosis has received less attention than other interactions such as predation or competition, it is increasingly recognized as an important selective force behind evolution, with many species having a long history of interdependent co-evolution.". Is that enough to answer the question?
Answer: no
