Kenneth Branagh - Narrator : He may not look like you or I, but this odd fish is becoming the blue print for our own bodies.
Kenneth Branagh - Narrator : Land at this time is like an alien planet. It's a barren expanse of roasting rock hotter than the Sahara. The air would be toxic to us: it has much less oxygen, and three hundred times more carbon dioxide than today.
Kenneth Branagh - Narrator : It is the arthropods, and not our ancestors, who have taken the first momentous steps out of the sea onto dry land.
Kenneth Branagh - Narrator : Brain has triumphed over brawn, and soon, they won't be such soft targets. Evolution starts to give them weapons to fight back.
Kenneth Branagh - Narrator : They're the first ever true vertebrate landlubbers. The very first reptiles. But as they move inland, they'll face an ancient enemy, more deadly than ever before: the arthropods are back!
