Inflammation also erodes telomeres, the «caps» at the ends of chromosomes that protect genes from degradation, which can lead to early cell death, premature aging and even cancer.

So it makes you think that, well, maybe that could have been one contributing factor to why we actually use genetic materials that incorporate ribose, because early cells that relied on an external source of ribose would have had easier access to that material compared to competing the cells that we're looking for, a different sugar that had a harder time getting across the membrane.

The scientists discovered that the development of these cells in the mouse fetus and in newborn mice proceeds in three distinct stages, parallel to those of the developing brain: early cells that populate the brain of the embryo shortly after its inception, pre-microglia and adult cells.

In particular, RNA enzymes can not readily adjust their activities to temperature changes likely to have happened as the earth cooled, and so can not perform the very broad range of catalytic accelerations that would have been necessary to synchronize the biochemistry of early cell - based life forms.
