Why are so many of my bluebells turning white?
Every year fewer and fewer of them produce blue flowers.
Is it changing soil pH ? Acid rain ? Global warming ? Global dimming ?

A reaction to the state of the Conservative party?

If you have a population that is shifting, you have something that is
scientifically interesting. I can't think of an obvious explanation,
and it might be unrelated to the colour (e.g. an advantageous gene
that happens to be on the same chromosome as a blueness gene).
