Letters from a Father | Episode 4 | The First Living Things

 

"When we examine the rocks carefully and collect all the old fossil bones that we find we can see that different kinds of animals lived at different periods. They did not all come together from nowhere. At first there are very simple animals with shells—shell fish for instance. The beautiful shells you pick up at the sea side are all the bony coverings of animals who have died. Later we find more complicated animals, snakes, enormous beasts bigger than our elephant, and birds and animals resembling those we have today. Last of all we find remains of man."
