On today\'s episode we\'re revisiting Mistaken Point, Newfoundland, Canada.\\xa0At this lagerst\\xe4tte\\xa0it is possible to find large bedding planes\\xa0full of\\xa0Precambrian organisms called rangeomorphs. These are an enigmatic group, which still can\'t be placed on the \'tree of life\'.

We are joined by Dr Emily Mitchell of the University of Cambridge, who\'s recent paper in Nature was able to show that you don\'t\\xa0need to be able to\\xa0fully understand the anatomy of an organism to discern some of its most intricate details.
