PZ Myers of
Pharyngula, in discussing evolution, recently claimed that the "Blue Fairies" did it. More specifically,
I could also point to some gap in our knowledge (of evolution), say that difficult and poorly understood transition from the prebiotic world, and say 'the Blue Fairies did it!'.
I think he wasn't being serious, but it can be hard to tell over on his "evolution" blog.
So I did some more research and I found this entry on the "Blue Fairies" at Wikipikipedia:
The Blue Fairies were a race of fairies from the 6th and 7th centuries who were well known in Royal circles in Europe for the blue hue of their skin.
OK, so this appears to suggest that the Blue Fairies were at the height of their powers only 1500 years ago, or so. However, the transition from the prebiotic world happened billions of years ago. Therefore I think PZ Myers is completely wrong to suggest that 'the Blue Fairies did it!'.
