comment Chiral (a)symmetry of curly hair (and fur)
I know that microscopic chirality is not needed to explain curly hair. The question is whether it plays any role, e.g. in shifting the ratio of clockwise and counter-clockwise curly hair from 1:1. (Thanks for the link, anyway; too bad for me that it is under a paywall).

comment Below which temperature human muscles don't work?
Thanks, especially for the last link. (I thought also about possibility that capillaries contract to much at lower temperatures, to support demand of muscles.)

Orders of magnitude difference of scale is not itself and argument against (see edit of my question).

comment Chiral (a)symmetry of curly hair (and fur)
@WYSIWYG Here keratin was only a guess. Chirality of intermediate fibers equally interesting to me. However the main question is: is proportion of left- and right-handed curly hair 1:1 in humans?

comment Is warmth/temperature sensed linearly or on a different scale?
Could you precise 'linearly'? In general, it is not a well-defined thing, when it comes to perception, see cogsci.stackexchange.com/questions/1751/…

comment Why did life not evolve to use radio?
See electrocommunication, weakly electric fish and Mormyridae. They use 500 Hz electric sine signals (however, AFAIK using conductance of water, not - electromagnetic waves).

comment Why did life not evolve to use radio?
A good point with amplification. For radio you want sine-wave amplifiers, not cascade amplifiers, so here there may be a problem as well. However, the first step is to have good wires...
