My father was a film-maker. He always said he wanted to go like Humphrey Jennings, the legendary director who stepped backwards over a cliff while framing a better shot.
Science fiction is never about the future, in the same way history is rarely about the past: they're both parable formats for examining or commenting on the present.
The usual sniggering examples of animal behaviour were brought in to explain cheating. Funny how the behaviour of shrews and gibbons is never used to explain table manners or road safety or gardening, only sex. Anyway, it was bad Darwinism. Taking the example of a monkey and applying it to yourself misses the point that animal behaviour is made for the benefit of the species, not as an excuse for the individual. Being incapable of sustaining a stable pair and supporting children is really not in the interests of our species. Neither is it really in the best interests of the philanderer.
If the world were to end tomorrow and we could choose to save only one thing as the explanation and memorial to who we were, then we couldn't do better than the Natural History Museum, although it wouldn't contain a single human. The systematic Linnean order, the vast inquisitiveness and range of collated knowledge and beauty would tell all that is the best of us.
