Title: Complex Extremophiles
Post by: Dartz on August 13, 2012, 12:31:48 PM
Sorry if these posts are too frequent, but I'm trying to be as scientifically accurate as possible in my writing. Google helps some, but I can't seem to find some of what I need. My strong suit is Astronomy, and some Physics, but I haven't studied much on Biology to do much.

The basic question is: Can Extremophiles, particularly temperature-based, form complex organisms? Is there anything that would prevent them from doing so?

extremophiles are pretty much all simple and single celled because it's easier to adapt. there are some complex ones though, i think: http://en.wikipedia.org/wiki/Giant_tube_worm (http://en.wikipedia.org/wiki/Giant_tube_worm)

Pompeii worms'/Alvinella pompejana have parts of their bodies which are persistently 353K, and only single-celled bacteria are known to survive in higher temperatures. They can become 10 cm long.

Well, is the planet that you are using, a hot planet or something? Because honestly, extremophiles are extreme for Terran life, so, who knows what would evolve on a world that is significantly hotter than ours (but is still able to support complex life).
