> Hi Ben, not sure how to interprete your critique. I am probably wrong to
assume that you reject evolution in favor of intelligent design. Can you
elaborate in a bit more depth please? With that senetnce I wanted to
emphazise the gradual nature of evolution:

No argument about the gradual nature of Evolution (and no, i'm not a creationist :-D ). What i was objecting to was the concept (which i think is a common misconception) that evolution is about the building up of complexity. Just think of parasitic worms, to take one example. Evolution has simplified them, not complexified them.
The reason i called the statement "Evolution is the gradual accumulation of complexity" a howler, is that it seems to betray a misunderstanding of evolution. It's not _about_ 'building up complexity'. That does happen, but it doesn't have to. Different environments lead to different evolved characteristics. I doubt that you can explain viruses with a conception of evolution that only increases complexity and never reduces it.
