You can draw a free body diagram with two 250N forces acting on the human, one from each side. The net force is 0 because the two applied forces cancel each other out since they are in opposite directions.
The SECOND graph represents selection that may lead to reduced variation. It is an example of stabilizing selection.
<h3>What is Stabilizing selection? </h3>
Stabilizing selection is a type of natural selection that leads to a decrease in the genetic variation of the population.
In Stabilizing selection, natural selection tends to favor an average phenotype and then can remove (select) extreme variations.
Stabilizing selection generates a modified bell curve graph in which the central portion is narrower and it is taller than the normal distribution bell shape.
