What is an environmental change that would favor the much larger peanut?
I need to describe an environmental change that would favor the larger peanut, and an environmental change that would favor the smaller peanut.
Well, the peanut grows best in a sandy, loam type of soil. Loam is a type of soil that has a lot of decaying organic matter in it, and sand can be composed of different materials, depending upon the rocks it comes from. Sand basically has large particle sizes, allowing water to properly pass through. Peanuts require about 29 to 35 inches of rainfall across a five-month growing period.
For large peanuts, probably a larger content of loam, since that is where the majority of the nutrients that produce the larger peanut will come from. So we need an environment that will produce a lot of decaying organic matter, such as found in forest areas.
For smaller peanuts, less loam and more sandy material. This will produce a reduced size peanut and make it easier to pull out of the ground upon harvest time. So less loam, more sand, like we would find in a typical open field area, probably closer to the equator.
