All You Need to Know About Dog Vomit Slime Mould 

A correspondent brought THIS ARTICLE to my notice. As she said it is not very geological - slime moulds (actually myxomycetes) have a limited place in the fossil record - but it is a fascinating read. 

If you want to know about a single cell that can grow as large as a bath mat, has no brain, no sense of sight or smell, but can solve mazes, learn patterns, keep time, and pass down the wisdom of generations, read the article!

The slime mould is used by the author to talk about the classification of nature and the creation of hierarchies. All in all a very good read.
