God's Natures wonder: Cell conducts anti-viral warfare (Introduction)

A single celled animal self-sacrifices itself and releases viral making protein to kill attacking virus:

"The infected Cafeteria cell still dies – but when it breaks apart it releases maviruses rather than CroVs, preventing the spread of the infection. This, then, is altruistic behaviour, which turns out to be surprisingly common among microbes. For instance, some bacteria kill themselves as soon as they are infected by viruses to prevent the infection spreading.

"Many viruses deliberately insert their genes into the genomes of the animals they attack, so they can lie dormant and emerge when conditions are favourable. In response, most animals have evolved ways of shutting down genes that code for viruses.

"It is, however, extremely unusual for an animal to deliberately trigger virus production, as Cafeteria does – but then mavirus is unusual, too, because it targets another virus rather than Cafeteria itself.

Comment: Another 'how did it develop' problem. Does the Cafeteria do this to protect others of its type? Or is it simply a byproduct of getting killed. And if that is true how did it develop and get passed on to subsequent generations. Death doesn't pass on bacterial inheritance, only cell splitting to daughter cells does that. God did it?

No comment so far on this. It is a very precise problem. If you, a single-celled organism die in a defense mechanism, how is it fixed into evolution for daughter cells to carry if the only way to pass on inheritance is splitting onto two daughters? This has got to be God as the causative agent!
