" Over the long term, our species, like every other, has just two possible evolutionary fates over the long term: extinction, or further splitting apart into a number of daughter species—each of which will either go extinct or split again. If we avoid extinction, each of our daughter species will probably develop distinctive styles of courtship display, and different ways to channel their sexual competitiveness into various forms of physical, artistic, linguistic, intellectual, moral, and economic display. Some may continue to live on our home planet, and some may move elsewhere. Some may shape their own evolution naturally through sexual selection, while others may shape their evolution consciously through genetic technologies. We cannot imagine the minds that our far-future descendants might evolve, any more than our ape-like ancestors could have imagined ours. That does not matter. Our responsibility is not to speculate endlessly about the possible futures of our daughter species, but to become, with as much panache as we can afford, their ancestors. "
