Therefore, a careful evaluation and selection of molecular markers for each individual project is required.Īdachi, J., Waddell, P.J., Martin, W. 2004 and Wörheide 2006 on CO1 in population studies) and unequal evolutionary rates among taxa (see e.g. However, some DNA markers suffer from insufficient phylogenetic signal (see e.g. DNA barcoding, see Wörheide & Erpenbeck 2007). DNA sequence markers are frequently employed to overcome morphological shortcomings in phylogeny (e.g. However, the phylogenetic relationships among Porifera are largely unsolved, because the simple poriferan bauplan frequently prevents unambiguous taxonomic species assignment and a clear definition of morphological synapomorphies is difficult (see e.g. It helps the understanding of character evolution among early branching metazoans but also aids in bioprospecting for valuable bioactive sponge compounds. Unravelling the phylogenetic relationships of sponges (Phylum Porifera) is an important as well as challenging task.
