Basis of Phylogenetics
Phylogenetics Definitions field of biology which does deal with identifying and field identifying understanding the evolutionary relationships among the many different kinds of life on earth, both living (extant) living dead (extinct) dead procedures for constructing procedures evolutionary trees a phylogeny describe the phylogeny historical relationships among lineages or organisms or their parts (genes) using trees to test hypotheses using Molecular Phylogenetics

two populations become reproductively isolated and two diverge due to random mutational processes over time, this process may repeat itself, so that at any time, over each population can be said to be most closely-related each to some other population with which it shares a direct common ancestor
If genomes evolve the by accumulation of mutations the amount of nucleotide sequence difference between a the amount pair of genomes should indicate how recently those two how genomes shared a common ancestor

Phylogenetic Divergence consists of changes in characters, such as amino acids in a consists changes protein, or nucleotides in DNA the the

longer two populations remain reproductively isolated, more divergence will occur
