It sa...It's like the straw man all over again.<br /><br />It said in the book (section 4.4.1) that eukaryotic cells cannot rely on simple diffusion, they instead employ a transport infrastructure. Taking this into account I would assume that organisms would simply evolve the means to survive if life is feasible.<br /><br />Actually in doing some background I found this other blog post from science 2.0 which is both relevant and interesting.<br /><br />http://www.science20.com/stars_planets_life/calculating_odds_life_could_begin_chance<br /><br />The quote at the end is particularly good.Heatherhttps://www.blogger.com/profile/13167610447846122237noreply@blogger.comtag:blogger.com,1999:blog-5834252248412211498.post-75363861186249948872010-08-15T16:51:12.862+10:002010-08-15T16:51:12.862+10:00I think if thermal motion was weaker or if molecul...I think if thermal motion was weaker or if molecules were bigger that it would be difficult to get the conditions in which life evolved. The precursor molecules of DNA/RNA may never aggregate. Also if diffusion is the simplest way of getting nutrients - and if this was no longer the case - how would the bacteria get energy to divide and thereby evolve more advanced ways of getting these chemicals i.e. flaggelum?<br /><br />It seems that heat is so fundamental that if you changed it you may change the way energy levels are distributed in molecules and thereby change the chemistry entirely.Calvin Lowehttps://www.blogger.com/profile/08534804973494602576noreply@blogger.com
