comment Why can't humans drink sea water?
@Sz. its true - most salt water organisms have osmotic control I think - even mammals eating salt water fish probably have adaptations for all that salt. I don't doubt that human beings could also have those adaptations, but they just dont at this point.

comment What is variation in Speciation
you should probably go to reddit with this question - they are more focused on handling such questions and dealing with the interface of the general public with science there.

comment Why we have no enzyme to digest cellulose?
there's lots of shades of meaning here, which is definitely interesting to talk about. Organisms are so optimal for selected traits that they amaze and astound us - better than we can design ourselves in many cases. Where selection has not had as much pressure (e.g. long life, resistance to damage and disease, empathy, speed, intelligence) it can seem that they are strangely vulnerable.

comment Where’s the flaw in my proposed TB Treatment?
also in tubeculosis, the mycobacteria go into tubecules and can remain in a dormant state for prolonged periods of time. Its unlikely this will kill those protected and dormant bugs.

comment How does decreasing surface tension of lipids help to emulsify them?
thanks - Bile salts are amphipathic I think.

comment Do butterflies pass over migration patterns to their offspring?
Thanks for the review @MattDMo I can't find any reference of Monarchs living longer than 8 months. I just re-reviewed several sites. post a link? the wikipedia article seems to refer to the fact that Monarchs have mulitple breeding waves (called generations) over the year where their lifespans can vary tremendously (4 wks <-> 8 mos).

comment How does decreasing surface tension of lipids help to emulsify them?
lipids have surface tension - and that's a good thing since it helps hold the cells together! - that seems like biology to me. its not clear to me what the 'gall' is but i imagine a non polar or amphipathic (polar and non polar) additive to the mixture will increase the solubility of the lipids in the mix
