Interesting that the higher orders can't make their own vitamin C, while the lower orders can. It certainly fits into change over time, but is it Evolution ? (accumulation of complexity?) or is it Devolution? (loss of complexity?).

You could say it's an increase of specialization. Which in economics at least is a hallmark of an economic entity (company, industry, country) that is growing & getting more sophisticated.

Yes, you could. But that illustrates the problem with the whole evolutionary construct. It doesn't much matter what the pattern is. Virtually any pattern can be explained so as to fit the theory.
