I came across a Web site today which will be of some interest to those interested in speculating about alien life: The Future Human Evolution Website at <http://www.humansfuture.org/>. Yes, it is about human life and not alien life, but speculating about the future of human evolution and speculating about alien life, especially alien sentient life, overlap. If there is a Universal Biology, then examining the evolution of human life, and the future of our evolution (both natural and artificially guided) will inform our discussion and speculations on the evolution of alien sentient life.
Technology Singularity - Or, We Are Borg
The overlap is particularly salient when it comes to speculations regarding the technology singularity - when technology advances to the point that it becomes sentient. This advancement also allows sentient races who feel they have reached the limits of what biology can do for them to integrate themselves (partially or, eventually, fully) with advanced technology/machines. This is also referred to as "postbiologic." Some scientists feel this technology singularity may arrive for the human race as early as 2040, though most feel that it is more likely to be much later, the year 3000 or so.
