>Bacteria don't desire anything, and they don't seek out anything or plan anything.

When you say this, aren't you are making precisely the same mistake you claim the expert was making?! I am sure Dr Arjun knows very well that evolutionary goals are local and specific to the circumstance a creature finds itself in.

>The intelligence that the hominid lineage has evolved gives human beings advantages that bacteria will never possess.

:-) how anthropomorphic! Intelligence may not be a survival trait as you seem to assume. We simply don't know that. Btw, bacteria has been a lot longer on this planet than primates. We are way out of our depth when it comes to understanding how they work (I am simply paraphrasing a friend's statement, he is doing fundamental research on biochemical pathways)
