Abstract
Conventional methods of phylogenetic reconstruction from DNA sequences require simplified models of evolutionary dynamics. We present a method based on fractal analysis to reconstruct the evolutionary history of organisms from mitochondrial DNA sequences. We map animal mtDNA into four-dimensional random walks and estimate their long range correlations using multifractal spectra. We see systematic changes in correlations in mtDNA sequences across taxonomic lines, which translate into changes in the scaling of the random walks. We use cluster analysis to group the multifractal spectra and obtain the phylogeny of the organisms. Though our method uses no a priori assumptions and is independent of gene order, it yields phylogenetic relationships broadly consistent with established results. Several recent papers have analyzed DNA using fractal analysis and have found long range correlations. However, no one has succeeded in using them to deduce biologically significant relationships.
