Just So Darwin
Why is Lonesome George so lonely? Animation telling the story of Lonesome George, the last Pinta Island tortoise in existence. Grandad Charlie, an elderly tortoise, takes his grandson Sam to visit Lonesome George. Lonesome George tells Sam a story to explain why he is lonely. Once there were many tortoises on the island, but then sailing ships arrived. The sailors and settlers needed food. Some of them caught and ate the tortoises. The ships also brought goats which ate the plants, so there was not enough food left for the tortoises to eat. The ships brought dogs, some of which also ate the tortoises, and the ship's rats fed on tortoise eggs. Before long almost every tortoise had gone and the island was changed forever. Fewer and fewer tortoises had babies, until only George was left. George tells Sam that when he dies, tortoises like him will become extinct.
