Calculating the expansion of the late amino acids from the cluster of earlies. This test first calculates the one, two, or three-dimensional mean of the true subset of 10 early amino acids (μ) and then calculates the average distance between each late amino acid and this mean (panel A). The same calculation is then repeated when amino acids are re-designated as 10 “earlies” and 10 “lates” at random (panel B).
