The Conceptual Evolution Forum is where you can connect with other speccers, posting about your own projects and commenting on others. Get feedback on aesthetics and scientific plausibility from thousands of people all over the world. There are different sections to discuss future evolution on Earth, what might have happened on Earth had evolution run differently, evolution on other planets, and other universes where the laws of physics are different. Popular projects include Nemo and Sagan4. Register and say hello.
