Meet Scotland’s most important stone wall, over 410 million years old. With it’s really stange markings and stains, underneith the dark features – we realize this was something that once was alive.

Meet the earliest pioneering plant –  Aglaophyton major. When they were alive – just a few centimeters tall with bulbous shapes a top naked stems – a time before leaves or roots, these strange life forms tied terrestrial life to the water’s edge. 

Consider today, soil covers 40% of land, these tiny organisms thrived for tens of thousands of years to create topsoil at a rate of 2.5 cm per 1000 years.

So that soil you are standing on – it’s ancient history.
