The phrase "as opposed to evolving" is correct and usable in written English.
It can be used to contrast two different ideas or actions, highlighting a preference for one over the other.
Example: "The company decided to focus on improving existing products, as opposed to evolving their entire product line."
Alternatives: "instead of developing" or "rather than changing".
Again, a significant increase in GC content is seen in the introns that appear to be evolving under concerted evolution, as opposed to the introns evolving divergently as well as 10 kb of upstream and downstream flanking sequence.
Evidence from complete viral genomes suggests that viruses differ from many other evolving lineages in terms of the quantity of genetic material they appropriate from other organisms as opposed to material they evolve themselves through genetic duplication and expansion events [1], [2], [3], [4].
Support for the hypothesis that staminodia evolved from stamens as opposed to being an independently evolved whorl is that the Aquilegia homologue of the C gene AG (TC8667) is most highly up-regulated in stamens, staminodia and carpels combined while, as discussed above, the B genes AP3-2 and PI are detected in both stamens and staminodia (Table 1).
This is evident even for the title: "A method for defining evolving protein-coding genes" — evolving as opposed to what?
Consequently, not only the translation machinery itself, but its coding toolkit, the code-adapting molecules (tRNA) and aaRSs (initially, advanced ribozymes, then minimalist primitive enzymes) have been evolving to "fit" the probably already basically outlined genetic code (as opposed to the code co-evolving with tRNAs and aaRSs to "fit" translation by minimizing translation errors).
My personal style, as opposed to everyone else's fashion, evolves from what survives in my wardrobe; that is, the pieces that sang to me from a clothes rail or a website and most accurately reflect who I am.
Those struggles reflect the fact that policies to help poor places — as opposed to poor people — haven't evolved much beyond the War on Poverty's neighborhood-based solutions.
I always knew that I would need a strong man from whom I could draw strength, and who would help me evolve, as opposed to a "yes, dear" type!
For both regimes, having two preferences evolving simultaneously (as opposed to successively) increased the size of the parameter space where a second preference fixed, allowing it to fix at higher levels of competitive costs.
