comment Hodgin-Huxley model for a single neuron
I think that since the question includes the answer and asks for an explanation, this is a legit question

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).

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

comment Are we more attracted to people of the same ethnicity?
One of the precursors to speciation is that different isolated groups stop mating with each other even if they are exposed to each other. I'll see if I can find a good link for the penguins, which is a specific example of this phenomenon.

Of course you are right. Marriage is not a bad statistic to look at because its more easily measured with less slippery subjective critiques. I'm borrowing from couples research in psychology which only took off when they started using divorce instead of qualitative satisfaction metrics. Few would argue that attraction is even more broad than marriage, though some might not admit it....

@augurar of course biology concerns itself with inherited and environmental aspects of behavior. Sociobiology and Ethology has informed social psychology and behavioral economics, and now literary crit and cultural crit. They are not as prominent today as biology departments have gone more and more molecular in the past 30 years, which has obscured the previous forms of the science.

comment Are we more attracted to people of the same ethnicity?
yes @AliceD - i thought i'd try to list other factors like geographical, socioeconomic, cultural separation, but the list is quite long. given all that its not surprising that not a lot of racial intermarriages are happening compared to the rates one would get from at random pairings. Its a lot like the factors cited in population biology, is it not? humans are picky for more reasons than animals tho I think..
