Compare the morphological phylogeny to molecular phylogeny -highlight the main point of difference Solution Both morphological and molecular phylogeny show evolutionary relationships amongst various biological species based on the similarities and differences amongst the ancestral species. Phylogenetic framework or trees, is based on morphological and developmental data in case of morphological phylogeny, whereas in case of molecular phylogeny it is based on molecular data such as DNA sequences. Whereas, the morphological data based phylogeny has limited information and scope based on phenotypic data, the molecular phylogeny is much advanced and uses sequence baased genotypic approaches with increased the number of characters. In many cases, it has been observed that both the approaches may deliver strongly contrasting hypotheses. Also, many lacuna were existing in morphology based phygenetic data which has not been filled and properly linked with the help of molecular phylogenetic analysis. However, for many ancestral species, even the fossilized DNA/genetic samples may not be available. In such cases, the phylogeny has to be built up based on morphological data only. The phylogenetic tree/ information is most authenticated if it has been built on the basis on both morphological features backed up by molecular characteristics..
