one would think, if our human prejudices are correct, that the simpler the organism, the easier we can manipulte it. The aids virus has put some craks in that theory, but still, wouldn't viruses bee the place to manipulate for bio-chemical-engineering? Or, how about prions? If yeasts are gonna bee uppity, why not drop lower?
My personal hunch is that the lowliest creatures are reflecting the loftiest intelligence. Our huuman ego prevents us from seeing the obvious: that our liver flukes are smarter than us. After all is said and done, survival is the only I.Q. test we have. So, how ya doin'?
