If you ever wanted a non-biology based allegory for the process of natural selection, I reckon there are two good candidates. The first would be fairy stories. As I wrote in this blogpost in 2008:
'With the exception of those that were popularised by Joseph Jacobs - and which now survive as pantomimes - most British fairy stories fell out of use through neglect. Instead of being told and retold and adapted and changed, they were preserved and archived by 18th century folklorists who collected and stored them away for posterity. It's good that they were not lost ... but the desire to 'preserve' them has left them as dry and dusty as pinned moths in a display case. To all intents and purposes they are dead, which is why our kids don't know any of them. How sad is it that young Cornish kids all know Andersen's Little Mermaid but don't know about the Mermaid of Zennor? Isn't it tragic that kids know all about Pocahontas but have never heard of The Wise Men of Gotham?'
British fairy stories haven't evolved in the way that European tales have. Little Red Riding Hood has gone through many changes and so it endures. 95% of traditional British stories are pretty much dead.
The other great allegory is the English language itself. I love that it is fluid and plastic and constantly changing. It evolves. Words die and new ones arise; the fittest survive and the dinosaurs become extinct. That doesn't mean we can't love them and be fascinated by them though.
We have a Thesaurus for synonyms and antonyms. Wouldn't it be fun to have something like a Lexicograsaurus to store all the extinct ones?
Here are a few that I love and which, like the stegosaurus and the pteranodon, I wish we still had around.
