Spatial trends in Ediacaran Bilaterian trails
The Savannah Hypothesis and the Cambrian Information Revolution invoke the development of spatially heterogeneous resource distribution during the Ediacaran-Cambrian transition as a key driver of infaunalization and sensory evolution of mobile bilaterians, respectively. However, difficulties in detecting historical resource distribution hinders the ability to tests these theories. If external conditions crucial to organism fitness (e.g. nutrient distribution, oxygen availability) became increas…
