WebThis pattern repeats as one goes through the phylogenetic tree of life: A change in an organism’s genetic makeup leads to a new trait which becomes prevalent in the group. … WebDistance matrices are used in phylogeny as non-parametric distance methods and were originally applied to phenetic data using a matrix of pairwise distances. These distances are then reconciled to produce a tree (a phylogram, with informative branch lengths).The distance matrix can come from a number of different sources, including measured …
