High-dimensional data in phylogenetics

What is high-dimensional data? The concept of high-dimensionality applies to data sets that contain a high number of variables, so high that it often surpasses the population sample size. For example, when the number of genes affecting a phenotypes is higher than the number of people the genetic data was drawn from. This is a statistical problem.
