The common feature of members of the family Ichneumonidea is that they are parasites. Various species can be found across the world, though they generally inhabit the northern hemisphere. With structures and appearance that have remained unchanged for tens of millions of years, ichneumon wasps refute the theory of evolution. There is no life form that evolutionists can propose as these wasps" supposed common ancestor. Neither can they explain through which stages these insects acquired their present features. No trace of any such ancestor can be found in the fossil record, nor any stage through which they might have passed. As with all other living things, stasis is the common feature of all ichneumon wasp fossils.
