Pleistocene playground
The oldest human footprints outside of Africa have been discovered by scientists on a Norfolk beach.
The footprints are claimed to be over 800,000 years old, and no others like them have been found anywhere in Europe. This immediately begs the question as to how those ancient humans got from Africa to England without leaving any traces in between. And this is in the days before they could have stowed away in a jet airliner's wheel bay.
The foot prints were revealed when rough seas eroded the sand beach at Happisburgh. But they didn't last for long; they were washed away within two weeks. How do they know that they weren't left more recently? It's not like they were fossilised.
The work was apparently published in the renowned internet comic PlosONE, although the link given in the BBC's article appears to be broken.
Curious.
