Some evolutionists have defended their theory by proposing a falsification test: the discovery of a Precambrian rabbit.  No such fossil has ever been found, partly because any stratum containing a rabbit fossil would never have been labeled Precambrian in the first place.  But evolutionists would be surprised at finding complex non-marine multicellular eukaryotes in Precambrian strata, and this has just been announced in Nature.
A team led by Paul Strother of Boston College with help from Oxford University and University of Sheffield has announced “Earth’s earliest non-marine eukaryotes.”1 “Direct evidence of fossils within rocks of non-marine origin in the Precambrian is exceedingly rare,” they said.  In Arizona, they found not only ambiguous traces, but oodles of clear evidence for freshwater eukaryotes:

Here we report the recovery of large populations of diverse organic-walled microfossils extracted by acid maceration, complemented by studies using thin sections of phosphatic nodules that yield exceptionally detailed three-dimensional preservation.  These assemblages contain multicellular structures, complex-walled cysts, asymmetric organic structures, and dorsiventral, compressed organic thalli, some approaching one millimetre in diameter.  They offer direct evidence of eukaryotes living in freshwater aquatic and subaerially exposed habitats during the Proterozoic era.  The apparentdominance of eukaryotes in non-marine settings by 1?Gyr ago indicates thateukaryotic evolution on land may have commenced far earlier than previously thought.

The date of one billion years is nearly twice as long ago as the Cambrian explosion.  The paper shows over a dozen specimens of different shapes and levels of organization, from spherical clumps of cells to others with differentiated structures.  “The Torridonian assemblages contain some striking examples of microfossils that show complexity that goes considerably beyond that of simple leiospheres” [i.e., nondescript clusters].  Some have vesicles, outer walls and armlike projections (thalli).  They figured these organisms were “approaching a tissue-level grade of organization.”….
