| Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web. While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself!

Hi guys could you help me answer a few questions? This is for some science project thing I'm doing in school. How would you detect life, directly or indirectly, on Mars? When astronauts return from Mars, how would you prevent the accidental introduction of a harmful agent or life form into Earth, which might have potential harmful effects onto Earth? As you work, you realize the mission to colonise Mars could take generations to accomplish. What would you initiate immediately, to inspire and motivate the next generation of students to become astrobiologists? Any feedback/opinions would be appreciated! |

1. Well I guess one very terracentric way would be to look for evidence of a biological input to the atmosphere caused by organisms gas exchange systems. Soil and water samples should yield results as well if organisms are present. 2 For that I would check out the Lake Vladivostok project, they seem pretty damn keen on keeping things sterile. 3. The problem with astrobiology is there are very few jobs in it. We need more engineers right now, dont run before you can walk... |

thanks for the advice! will check it out... but how would you encourage people to become engineers, other than playing tf2? what is this lake vladivostok thing? |

Simple, get them to watch the Big Bang Theory. Over in England University applications for engineering and physics have tripled due to the increased televised nature of science. Brian Cox and the Big Bang Theory are possibly the two big reasons. Both are showing that it is cool to be nerdy. |

Well the only way to confirm it is to do proper biology, go grub around a bit and find a microbe. But there are other signs you could look for. For example, naturally methane would rapidly disappear on Mars, so if you could detect it then it would mean that either there is life on Mars, or volcanism. In related news, there is more methane on Mars than their ought to be. Finding liquid water would be good too, and wherever it exists on earth something lives in it. That's quite unlikely, anything on Mars will be an extremophile, and they aren't taking over the earth. But to be safe we'll probably quarineteen the crew like they did with the Apollo missions. ![]() Vladivostok is A Russian city on the Pacific coast, not far from Korea. Dial must mean Lake Vostok, which is a lake in Antarctica which has been sealed off from the outside with by ice for millions of years and there are plans to drill into it and take samples of the microbes down there. http://en.wikipedia.org/wiki/Lake_Vostok Parasky does not like that, I said it was like a more science oriented version to Mythbusters (as opposed to engineering) and he got really angry and pushed me over.

Maybe in America its mythbusters, but over here everyone my age (those who are about to apply to university) all watch the big bang theory. Yeah Lake Vostok :') |

Maybe because it gets redubbed over here. I don't see why we need a different narrator. |

We have decontamination procedures well established. The astronauts that returned from the moon went through it, just to make sure. |

We should all aspire to die surrounded by our dearest friends. Just like Julius Caesar. "The Lord Universe said: 'The same fate I have given to all things from stones to stars, that one day they shall become naught but memories aloft upon the winds of time. From dust all was born, and to dust all shall return.' He then looked upon His greatest creation, life, and pitied them, for unlike stars and stones they would soon learn of this fate and despair in the futility of their own existence. And so the Lord Universe decided to give life two gifts to save them from this despair. The first of these gifts was the soul, that life might more readily accept their fate, and the second was fear, that they might in time learn to avoid it altogether." - Excerpt from a Chanagwan creation myth, Legends and Folklore of the Planet Ghar, collected and published by Yieju Bai'an, explorer from the Celestial Commonwealth of Qonming Tree That Owns Itself
