The Curl of the Fern

Here’s another fern themed image, this time showing the plant in its curled up state.

What did this image teach me?

Last time I revealed the life cycle of the fern, this time I learned that ferns first appeared in the fossil record around 360 million years ago – which means that ferns have lived through 4 “mass extinction” events (you know, the sort of events that wipe out almost all life on the planet when they happen)!
