Question

Why is morphological difference sometimes is poor indicator of toxonomic classification?

Answer 1

In my opinion molecular taxonomy does not exist without morphological or classical taxonomy . molecular tools help you to differentiate the species where you are not able to do that with external morphological characters. Most of the cases hard parts are able to clear these type of ambiguity too. Any body who is bar coding a species without identification using morphological characters should be care full, one may land up in wrong identification.
