Heat Helped Hasten Beginnings Of LifeChapel Hill NC (SPX) Dec 06, 2010 There has been controversy about whether life originated in a hot or cold environment, and about whether enough time has elapsed for life to have evolved to its present complexity. But new research at the University of North Carolina at Chapel Hill investigating the effect of temperature on extremely slow chemical reactions suggests that the time required for evolution on a warm earth is shorter than critics might expect. The findings are published in the online early edition of the Proceedi ... read more |
