Define "complex". Because multicellularity has arisen independently in something like ten or twenty groups. There's metazoans (and parazoans like vendobionts and sponges) and viridiplantae and rhodophytes and glaucophytes and fungi and a few other weird groups scattered across the eukaryotic tree.

the problem with comparing Feldman et al. (2015) to Stephens et al. (2012) is that one is looking at changes in the MEASURED intensity of infrared radiation FROM the troposphere TO the surface (a metric for the strength of the greenhouse effect), and one is looking at changes in the total ESTIMATED energy balance of the earth.
you're comparing apples to oranges, using the difficulty of quantifying the total inflow and outflow of energy from the earth to claim that we can't quantify a particular set of changes to the near-equilibrium system.

it's like saying we can't be sure how much sand we've added to a large sandbox, because we can't weigh the whole sandbox itself.

I only took a few quarters of cell/molecular bio before switching over to eco/evo. how does one, without knowing what dye is in use, distinguish actin structures from tubulin structures?

A shit bunch of mutations happen in a very large population of bacteria. Some of them might happen to confer resistance to some antibiotic. IF the population is exposed to that antibiotic, the cells with the resistance mutation will be much more likely to survive, and will pass on that mutation to their progeny.
TL;DR there's no intent involved, and it's not deliberate. it just looks that way sometimes.

Now that's vague... I'm currently working on complex analysis too and I cant see how it may help me in my case. Please enlighten me.
