comment Why do some people find vegetables so repellent when evolutionarily they should find them an attractive and thus tasty food?
Though in retrospect, I'm not sure anything about attractiveness, i.e. sexual selection, is very relevant to evolution of taste - at the very least considering that overcoming our sense of taste is a pretty easy thing to do in order to increase attractiveness (which is very evident today).

I must humbly apologise for this most intolerable shortcoming of mine, I shall endeavour to re-read every word I write on the internet at least every six months! [I actually did re-read the whole thread earlier, but failed to make the connection] On topic, I would expect overweight to be indeed related to micronutrient deficiencies - in that overconsumption of food (particularly the kinds of foods available in such cultures where overweight was considered attractive) would simultaneously at least prevent deficiency.

@octern Thanks for your comment! Could you clarify how micronutrient deficiencies relate to the question, answer or my comment earlier?

comment Are there sterilisation methods that do not denature proteins as heat does?
I'd recommend removing the claim about human health as it's very questionable. Sterilisation by heat can, depending on the actual temperature, indeed denature proteins. Similarly, strong radiation will ultimately break molecules. I can't tell you whether the levels used to sterilise milk are sufficient to denature anything contained in it though. In general of course, "Are there sterilisation methods that do not denature proteins as heat does?" should be a valid question.

Hi there and welcome! The link you provided is very useful, but please expand your contribution into a proper answer to the question, otherwise I would recommend posting this as a comment only :)

comment Are neural connections one-way?
Dendrites don't transduce action potentials. They convert various inputs into membrane potential changes which propagate along them by diffusion towards the cell body. All incoming signals ultimately influence the potential gradient across the membrane of the axon hillock, where an action potential will begin if the depolarisation is large enough. en.wikipedia.org/wiki/Neuron#Anatomy_and_histology

comment What limits our healing speed?
The limiting problem is the formation of new tissue. New cells could indeed be produced faster, but forming tissue requires much more than just cells. It requires extracellular matrix to provide attachment for new cells, collagen and various other intercellular fluid components (which are secreted by fibroblasts), migration of cells. And bear in mind all of this isn't done on an open end, it needs to be done without actually at any point breaking the blood circulation system or other boundaries between tissue compartments.

comment How did people who were living far from the sea obtain iodine during the Middle Ages?
@ddiez I think iodine is a bit too specific to warrant a tag and thyroid hormones as a tag only indirectly describes this question; I think it's prefectly appropriately tagged

Unfortunately exactly that :/ This question fits several of the "what not to ask" examples in the FAQ. (biology.stackexchange.com/help/dont-ask) You can of course bring these sort of things to chat! (link at the bottom of the page)

comment Why aren't introns found on the ends of pre-RNA?
Neither pre-mRNA or mature mRNA begin with exons, they begin with the 5'UTR. Are you asking why the sequence after the 5'UTR is always an exon? Or are you asking why there can't be introns before the 5'UTR?
