US researchers think they've set medical science on the path to curing the common cold by mapping the 'family tree' of the rhinovirus. Good news you would think, but perhaps not. It seems that viruses could be one of the drivers of evolution, and an explanation for why there have been interesting discoveries like the presence of snake DNA in cattle and gerbils. Stopping viruses infecting us might be stopping evolution dead in its tracks and rendering future generations inviable.
Unintended consequences indeed.
