No, it does not. The less faith people put into the ‘evolutionary explanation’, the more water it holds. Everything that is not forbidden is allowed; as long as the two versions both exist, there is no better one.

This reads as trying to sound wise. Population and diversity of habitats are a big deal for evolutionary fitness.
The reason the measurement ‘boggled the mind’ a few posts back is because YOU would have to go out and perform the experiment—you would have to collect the data, you would have to categorize the situations, etc. It’s too much. Also, the orchid example was a toy example. The question is too specific to even admit a statistical answer. But Lichen vs Fungus and Algae? Just take a bunch of samples and stick them down together and separately, over a wide range of locations and situations. Since you’d actually be sampling the overall space of interest instead of hyper-focusing in narrowly on orchid batch A vs orchid batch B, you can get an actual answer, like “In environments A, B, C, D, E, the algae thrive alone and the fungus die alone, but lichen thrive. In environments F, G, H, I, J, The algae and fungus die alone but lichen thrive. In environments K and L the algae alone survive but both fungus and lichen die. …”
The only thing mind-boggling about this is the work involved in making the measurement, not trying to figure out whether the question makes sense.
Also, this rather resembles what has been done—without proper monitoring, to be sure, and insufficient separation of the lichen components when it expands into new territories, and when either component expands into a new territory without the other no effort is made to bring the other along… but aside from those weaknesses, this is more or less what evolution has been doing. Trying everything and seeing what works best, as you say.
IF lichen dominates the performance of either component in any environment at all, then the statement that ‘the sum is greater than the parts’ is to some extent justifiable. The more such environments there are, the more it applies. If the two components do really badly except together, then it’s very reasonable!
I thought the point of this post was the meta-level of whether such phrases ever make sense, not the more object-level of whether they make sense in this case.
The point was that using such phrases in front of the kids nurtures in them the habit of making highly incontestable statements requiring lots of disclaimers the kids can’t think of, because they don’t know enough stuff, and that’s OK for them. The point was that I, personally, learned names for some (biological) concepts long after I was presented with the ‘meat’ of them, and I don’t know if it is a good thing. But whatever, lichens are very interesting, too.
Measuring it would be a ridiculously exhaustive task, but it seems like evolution has already performed the measurement for us.

Yes, of course, it is reasonable; I have just not read any report on this, whether positive or negative. Will have to repair that gap.
