If there's any plant life on the planets, it'd probably have black leaves so as to draw out every last bit of light from the feeble M-type star. |

However, Silicon could be substituted as the basis for life, but it would be far more difficult( and limiting) and therefore highly unlikely. As far as "liquids"(solvents) for the needed chemical reactions, water is considered essential. |

 Sponsor | tonyenkiducx | Mar 27, 2:17am | #194 Well that's just one theory, but there's a lot more thought these days going into alternative methods of sustaining life. Carbon is indeed ideal, and silicon is considered useless for an oxygen based environment, but then it doesn't have to be an oxygen ridden environment. Water is probably the easiest bit to replace, but it would require some radical changes in environmental conditions.
Anyhow, Wikipedia sums up my thoughts on this. Allthough I should say it is our particular setup that seems to be the most likely, but then wouldn't we naturally think that?
