How did the first creatures make it to land?

Leaving the Sea

Evidence from the fossil record tells us that life on Earth began in the sea. But just how and when did it crawl up onto land and what were the first terrestrial animals like? In this week's Frontiers, Peter Evans tracks down these hardy little beasts, whose footprints have been discovered in the ancient sandstones of Ontario in Canada.

Fossilised tracks in the sand, dating back 500 million years, offer the earliest evidence so far of animals coming onto land for the first time. No one's sure what they would have looked like but imagine a foot-long, armour-plated woodlouse and you won't be too far off the mark. So how did these first terrestrial creatures move about and what sort of environment was waiting for them? And now that we know what came up from the deep and when, the questions remains - why? Did they jump or were they pushed?

Join Peter Evans as he follows the trail of Earth's earliest land inhabitants as they ventured into undiscovered country.
