Four decades ago, Dougal Dixon used "thought experiments" based on evolutionary and ecological principles in his book After Man (1), to imagine what adaptations species may develop in a future after humans disappeared. For example, he imagined that pytherons, a group of carnivorous mammals evolved from rats, would fill the ecological niche currently occupied by seals in the polar oceans. Pytheron evolution included fin-shaped limbs and a streamlined body, better adapted for swimming. His book on "speculative evolution" is a reminder that making specific predictions about trait evolution in nature, in many cases, belongs more to science fiction than to science. Indeed, evolutionary ecology has yet to build a predictive framework that allows forecasting how genetically encoded traits may respond to known selective pressures (2, 3).
What is happening in the field of evolutionary and genetic algorithms today? Are there any cutting edge scientific projects in terms of AI/AGI? I'd very much appreciate it if someone could link me the relevant websites, researches, papers regarding the subject along with respective books or monographs. I'm just trying to find things out and getting back on track.
HOW did human same-sex attraction come to be? At first glance it seems to be an evolutionary paradox. For a trait to evolve, it has to be passed on to children to whom it confers some sort of advantage. But as gay sex, of itself, cannot yield offspring, we should expect same-sex attraction to go extinct. Evolutionary biologists have long struggled with this paradox, but my colleagues and I believe that if you come to the puzzle from a different angle, the apparent contradiction disappears.
