Go away 4chan. That done: melanin under UV fire.
A. niger is a black mold. Melanin is just the result of proteins and a mold has DNA code to produce it just like humans do. The argument here is that, besides the purple bacteria which feed off of methanes, a black mold is king when the ultraviolets run too high. In amplitude; we'll get to frequencies...
UV can get that high when the sun flares... as happens a lot on Prox next door. But also UV is high when the UV is too... low. It seems counterintuitive (to nonregular visitors here) but if there be oxygen but the lightcurve is too low for "UV-C" to push ozones, the low-freq/high-wav UV-B breaks through. Life can't get out of the shallows. There's the K stars ruled out.
All this suggests dark lichens colonising the shores. Earthworms of course. Bugs under the shade. There might never be vascular plants or land vertebrates.
BACKDATE 12/31 h/t the wonderful one.
