Christopher Lloyd
18 Oct 2009

Author Christopher Lloyd has developed an online game to help promote his new book What on Earth Evolved? 100 Species that Changed the World (Bloomsbury, October).

The five-minute game, said to be loosely based on the board game "Snakes and Ladders", tests your knowledge of the natural world.

Lloyd is set to donate £1 from the future proceeds of the book to environmental charities for each player, to a maximum of £5,000. The game can be played at www.whatonearthevolved.com
