Blondes to die out?

There's a BBC news article (not April fools) published a few years ago that says that blodes may die out. Hmmm. The article states:

The researchers also believe that so-called bottle blondes may be to blame for the demise of their natural rivals. They suggest that dyed-blondes are more attractive to men who choose them as partners over true blondes.

It then has a photo of Ann Widdecombe and says:

Bottle-blondes like Ann Widdecombe may be to blame

Hmmm... Firstly, I can't think of anyone that Ann Widdecombe is more attravtive than. Secondly, never trust news / articles from unreliable sources like the BBC (they still havent corrected it) or The Sunday Times. Luckily I found it was a myth from Wikipedia.
