Please defind "weed" before we continue this discussion. It's not a particularly rigorous term. Dandelions and kudzu are both weeds. Would you expect them to interbreed? Why or why not?

The article describes a hybrid of two different kinds of weeds which is unable to breed with either of the parent plants. Dismissing this discovery with the statement "so what, all three are weeds" betrays a fundamental ignorance of biology.

Theories change to accomodate new evidence. Unless you have evidence that some kind of special creation event took place, this little bugger is a confirmation of the evolutionary process.

Actually, one of many possible processes. I was unaware that a hybrid could be both self fertile and infertile with both parents. Another trick in Ma Nature's bag.

It indicates at least two things: that we don't know everything, and that new bits of learning always seem to diminish the list of impossible and improbable things.
