This is possible if both species evolved with a strong sense of morality or if each species had something to gain by good relations with the other.

i think it's very likely. i believe it may already be happening with humans and apes considering all the research that's been going on with human/ape communication. they are far more sentient than i think most people realize ;)

I would wonder the same thing. Perhaps the following explanation from Answers in Genesis should help the anti-evolution cause along its fateful path: Although the mutant bacteria can survive well in the hospital environment, the change has come at a cost. The altered protein is less efficient in performing its normal function, making the bacteria less fit in an environment without antibiotics. Typically, the non-mutant bacteria are better able to compete for resources and reproduce faster than the mutant form. Let’s look at a famous example to help clarify this. During the anthrax scare shortly after the September 11, 2001, attacks in the U.S., Ciprofloxacin (Cipro) was given to potential victims. Cipro belongs to a family of antibiotics known as quinolones, which bind to a bacterial protein called gyrase, decreasing the ability of the bacteria to reproduce. This allows the body’s natural immune defenses to overtake the infectious bacteria as they are reproducing at a slower rate. Quinolone-resistant bacteria have mutations in the genes encoding the gyrase protein. The mutant bacteria survive because the Cipro cannot bind to the altered gyrase. This comes at a cost as quinolone-resistant bacteria reproduce more slowly.4, 5, 6 Resistance to this family of antibiotics is becoming a major problem with one type of bacteria which causes food poisoning. This bacteria increased its resistance to quinolones 10-fold in just five years.7 Bacteria can also become antibiotic resistant by gaining mutated DNA from other bacteria. Unlike you and me, bacteria can swap DNA. But this still is not an example of evolution in action. No new DNA is generated (a requirement for molecules-to-man evolution), it is just moved around. It’s like taking money from your left pocket and putting it into your right pocket—it doesn’t make you wealthier. This mechanism of exchanging DNA is necessary for bacteria to survive in extreme or rapidly changing environments like a hospital (or like those found shortly after the Flood).8 What Does It Really Prove? The mechanisms of mutation and natural selection aid bacteria populations in becoming resistant to antibiotics. However, mutation and natural selection also result in bacteria with defective proteins that have lost their normal functions. Evolution requires a gain of functional systems for bacteria to evolve into man—functioning arms, eyeballs, and a brain, to name a few. Mutation and natural selection, thought to be the driving forces of evolution, only lead to a loss of functional systems. Therefore, antibiotic resistance of bacteria is not an example of evolution in action but rather variation within a bacterial kind. It is also a testimony to the wonderful design God gave bacteria, master adapters and survivors in a sin-cursed world. Are all bacteria bad?
