Nature just is

What better way to start 2013 than with a meaningful quote from Jon Yewdell:

We might think we know how Nature should work, and we certainly gain insight into Nature by using our logical powers (endowed by Nature) to predict how Nature might work, but ultimately, we have to understand the way Nature does work. Nature, in all its glorious complexity, is completely impassive. It cares not a whit what we may or may not believe. Nature just is.

It’s astounding how many scientists don’t really get this.

Jon’s statement includes the subject of this blog – viruses – which have no intentions or desires. Viruses are the product of mutation and selection, the goal of which is simply existence. Evolution does not move viruses along a trajectory aimed at perfection. Change comes about by eliminating those viruses that are not well adapted for the current conditions, not by building something that will fare better tomorrow.┬áViruses just are.
