This spins out of a separate discussion I was having, and I think it's worthy of a thread in and of itself, about the rationalisation of romantic feelings as a trait among Transformers. Some people argue that without sex in a species, romantic feelings can't or shouldn't exist, as they are simply the prerequisite for making and nurturing offspring. Since we don't know any real life asexual sentient species, we don't have any evidence for or against this, but theoretically, it's a bad argument. To start off with, it's hard to use evolutionary theory to justify or criticise any of the existing traits in Cybertronians, because in most continuities, they simply don't evolve. They don't pass on their genes to any progeny, either sexually or asexually. Individuals are either constructed, or spawned from a single entity or phenomenon, or part-cloned. Evolution only happens when different members of a species with different genetic traits are competing with one another to pass on their genes. In the case of Cybertronians, the traits they possess are either completely random, or they're the result of a guiding intelligence, or they're programmed through some other process that we can only guess at. If they're completely random, then the capacity for romantic feeling is not more or less strange than any other trait. If they're the result of a guiding intelligence - the Quintessons, or Primus, or Vector Sigma - then it completely depends on the whims and intentions of that intelligence. Primus might give his creations the capacity for romantic feeling just because he thinks it would be nice for them. The Quintessons might do it because they want to simulate the routines of other life-forms elsewhere in the universe. And so on. However, we could postulate, perhaps, a form of pseudo-evolution, where Vector Sigma or Cybertron, or whatever is spawning Cybertronians, is inclined to create progeny that live longer, and is constantly learning from its successes and failures. In which case, romantic feelings could well emerge as a trait that helps ensure survival. The ability to form an intense personal bond with another individual of the same race would be a form of symbiosis - essentially, two heads are better than one. Now, you could argue that a form of small-scale socialism would be preferable to romantic pairings in this case, ie. groups of people that look out for one another have a better survivability rate than couples. But think of efforts to run communes and form pan-romantic clusters, which very often don't work out. Understanding and cooperating with one other individual in a complex, intelligent species is hard enough - understanding and cooperating with several is several magnitudes harder. We could postulate that the optimal arrangement is a social order which involves both couples *and* groups. I think this gets us well clear of the finish line for establishing any basis for romance in the comics, but let's see what everyone else thinks.
