I didn't know this when i gave the song the name but:
One of the key species that allows us to date an archaeological site to a specific period of time is the water vole. These small rodents evolved changes that can be cross referenced and spatially and temporally compared. Most importantly, the teeth of the very early, pre-Boxgrove water voles have roots. Later in England and Europe, the water voles evolved so that their teeth became unrooted and continuously growing. These changes can be interpreted like divisions on a clock face, allowing us to use the 'vole clock' with confidence for the minimum age of (a given site) at 478,000 years ago. Dr. Wenban-Smith (time team) said "The vole clock is one of the wonders of modern science. It is truly incredible that the tiny remains of these creatures are so well preserved. For many sites it is the most accurate way of dating, and they also provide wonderfully precise information on the climate and local environment."
wow indeed, i thought the words fitted together perfectly. I wonder if the song has anything subliminal in it.
