Answer:
The interaction between the FUTI gene
Explanation:
Desertification is the process where fertile land becomes a desert.
Well one way desertification could impact an environment could be by a problem called OVERGRAZING.
Overgrazing happens when goats and cattle are kept in the same area for too long which results in then eating all the vegetation. If all vegetation is eaten, it is unlikely for it to grown back. Changes in political boundaries and companies buying land means that farmers rely on the water and land around them. This means farmers don't regularly move to new fertile areas.

To fully understand the processes occurring in present-day living cells, we need to consider how they arose in evolution. The most fundamental of all such problems is the expression of hereditary information, which today requires extraordinarily complex machinery and proceeds from DNA to protein through an RNA intermediate. How did this machinery arise? One view is that an RNA world existed on Earth before modern cells arose (Figure 6-91). According to this hypothesis, RNA stored both genetic information and catalyzed the chemical reactions in primitive cells. Only later in evolutionary time did DNA take over as the genetic material and proteins become the major catalyst and structural component of cells. If this idea is correct, then the transition out of the RNA world was never complete; as we have seen in this chapter, RNA still catalyzes several fundamental reactions in modern-day cells, which can be viewed as molecular fossils of an earlier world.
