Life and the look of landforms

Geomorphologists report surprising similarity in landforms on Mars with landforms on Earth, considering the importance that soil life has on landform processes. They conclude:
"Despite the profound influence of biota on erosion processes and landscape evolution, surprisingly,…there are no landforms that can exist only in the presence of life and, thus, an abiotic Earth probably would present no unfamiliar landscapes," said Dietrich.

It's a thought provoking read, especially for those of us who interpret the land at the more arid end of the spectrum.
