Phylogenetic Tree of DNA Sequences Constructed by a New Method-H Curve

The paper puts forward a new graphical representation of DNA sequences -- H curve, gives the definition of H curve and the relationship between H curves and represents mitochondrial DNA sequences by H curve for the first time. Through calculating the distance of H curve compressed to get the distance matrix of mitochondrial DNA of eight species, then use Kruskal algorithm to construct the DNA sequence phylogenetic tree.
